The disclosure of each prior application is incorporated by reference herein in its entirety.

The present invention relates to novel synergistic dietary supplement compositions comprising at least two ingredients selected from the extracts and fractions derived from Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Garcinia mangostana, Citrullus lanatus, Ocimum sanctum and Cinnamomum tamala as natural energy enhancer for enhancing physical performance, muscle strength and energy levels in a mammal.

The present invention further relates to food ingredient formulations such as beverages, dietary ingredient formulation, snacks and energy drinks containing the said herbal ingredient or its compositions for onset and steady maintenance of energy, muscle strength and mental alertness and for enhancing muscle power, physical activity, physical fitness, mental alertness, energy levels, stamina levels, circulatory health, blood vessel health or for better physical and mental health.

The basic force and condition behind all activities of human life is the presence of energy. Energy is the vital principle needed to sustain life and it is required for every aspect of existence—every act uses energy—thinking, feeling, walking, eating, drinking, dreaming, breathing etc. Energy is felt and experienced upon its expenditure. The energy we experience immediately after eating (such as sweets), or the hype we get following the consumption of coffee is from the expenditure of energy from body's energy reserves, not through its accumulation. Age, fatigue and stress make people feel deficient in energy. This drag in energy very often compromises body's mental alertness. The efficiency at work place and in personal management can be enhanced by addressing body's energy demands properly.

Dietary supplements are used by physically active people or weak people to increase their physical performance, physical fitness, improve their health, or reduce the potentially negative consequences of physical activity such as injury and chronic fatigue, or suppressed immune function.

Many energy beverages, supplements and food ingredient formulations are presently available in the market, but they are fully loaded with disaccharides, carbohydrate complexes, proteins, amino acids and vitamins along with numerous other agents. Many of these formulations act too quickly to give instant energy and not sustain the levels over period of time. Besides, these formulations tend to increase the blood glucose levels sharply and this is followed by their rapid depletion. This might sometimes lead to complications. Natural supplements, which improve the feeling of being energetic, general agility, endurance and mental alertness are thus in great demand. Many research groups across the globe are working on developing a superior product to address the above requirements.

Therefore, the present invention addresses the existing need in the art by providing an extracts, fractions or compositions that provides energy and/or mental alertness. Thus, the present invention provides ingredient(s) and/or composition(s) capable of increasing energy levels for an extended period of time in a mammal to enhance energy levels, muscle power and mental alertness and thus solves these needs.

The present invention provides novel synergistic dietary supplement compositions comprising at least two ingredients/components selected from the extracts or fractions derived from Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Garcinia mangostana, Citrullus lanatus, Ocimum sanctum and Cinnamomum tamala, which are capable of increasing energy levels for an extended period of time, improve muscle power and mental alertness.

In an important aspect, the invention provides novel synergistic dietary supplement compositions comprising at least two ingredients/components selected from the extracts or fractions derived from Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Garcinia mangostana, Citrullus lanatus, Ocimum sanctum and Cinnamomum tamala for the onset and steady maintenance of energy, muscle strength and mental alertness and for enhancing muscle power, muscle mass, physical activity, physical fitness, mental alertness, energy levels, stamina levels, circulatory health, blood vessel health or for better physical and mental health in a mammal.

In yet another aspect, the invention provides a method of increasing energy to provide an onset and steady maintenance of energy, muscle strength and mental alertness in a mammal, wherein the method comprises supplementing or treating the said mammal with the compositions comprising at least two ingredients selected from the extracts and fractions, derived from Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Garcinia mangostana, Citrullus lanatus, Ocimum sanctum and Cinnamomum tamala.

The invention will now be described in detail in connection with certain preferred and optional embodiments, so that various aspects thereof may be more fully understood and appreciated. However, any skilled person will appreciate the extent to which such embodiments could be extrapolated in practice.

The plants used in the present invention viz., Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Cinnamomum tamala, Citrullus lanatus and Ocimum sanctum were collected from the plants originated in India and Garcinia mangostana was of South East Asian origin, mostly from Indonesia. It is presently being cultivated in South India.

The basic force and condition behind all activities of human life is the presence of energy. It is thus essential that during exercise we require more nutrients and oxygen through enhanced blood circulation in working muscles. Nitric oxide produced by vascular endothelial cells is known as a potent vasodilator, which makes blood vessels to expand thus providing more supply of oxygen and nutrients to the muscle cells during workouts. Thus it helps in prolonging the endurance during exercise and physical activities.

Adenosine Triphosphate or ATP supplies the chemical energy that fuels muscular activities. For the first 5 or 6 seconds of muscle power, muscular activity is dependent on the pool of ATP that is already present in the muscle cells. Beyond this time, new amounts of ATP must be formed to enable the activation of muscular contractions that are needed to support longer and more vigorous physical activities. Therefore, it is essential to increase the intracellular energy source or ATP content during endurance exercise or for longer and intense period of physical activities.

Protein is an important component of every cell in the body. Proteins are synthesized in the cells through translation process of mRNA utilizing amino acids. It is the primary building block of muscles, bones and cartilage; and is essential for muscle growth and repair. Therefore, stimulation of muscle protein synthesis is a very important and crucial factor for increasing muscle mass.

Based on the above, we hypothesized that the herbal extracts, fractions or their compositions/formulations which can enhance nitric oxide synthesis in endothelial cells; increase ATP content and trigger protein synthesis in skeletal muscle cells would be ideally promising for increasing energy and endurance level, and muscle mass in physical performers such as body builders, athletes etc. Therefore, we intended to screen the herbal extracts and their compositions to assess their ability to increase the synthesis of nitric oxide in endothelial cells, intracellular ATP and protein in skeletal muscle cells.

In the present invention, a large number of extracts derived from plant materials were screened using cell based assays for the modulation of nitric oxide, ATP and protein synthesis. During the study it was found surprisingly that the extracts or fractions derived from Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Garcinia mangostana, Cinnamomum tamala, Citrullus lanatus and Ocimum sanctum potently modulates nitric oxide (Table 1), ATP (Table 6) and protein synthesis (Table 7). To further obtain a product with improved activity, the extracts or fractions of above plants were combined at different ratios and the compositions so obtained were tested for the modulation of nitric oxide, ATP and protein synthesis. It was found surprisingly that the compositions comprising at least two extracts derived from Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Garcinia mangostana or Cinnamomum tamala shows synergistic enhancement of nitric oxide, ATP and protein synthesis. Sphaeranthus indicus extract (LI12500) and its composition (LI12522F2) in combination with Coleus aromaticus extract (LI34103); Cissus quadrangularis extract (LI05704), and its composition (LI89032F3) in combination with Curcuma longa extract (LI09703) and Garcinia mangostana extract (LI80013) and its composition (LI80020F3) in combination with Cinnamomum tamala extract (LI33603) were assessed for their efficacy as energy booster and muscle building dietary supplements in a protein assay using L6 rat skeletal muscle cells, as nitric oxide enhancer using nitrate assay in ECV304 human endothelial cells and as ATP enhancer using ATP assay in L6 rat skeletal muscle cells. The compositions LI12522F2, LI89032F3 and LI80020F3 were found surprisingly to be synergistic as they exhibited better efficacy when compared to their respective individual ingredients.

The efficacy of the compositions LI12522F2, LI89032F3 and LI80020F3 for enhancing energy and endurance was further evaluated in an animal study. Swiss albino mice were orally treated with vehicle or 150 mg/kg of LI89032F3 or LI12522F2 or LI80020F3 or 150 mg/kg of L-Carnitine or 10 mg/kg Caffeine for 21 days. On day 21, one hour after the treatment the mice were forced to swim with a constant load (10% of its body weight attached to its tail) in an acrylic cylinder filled with water. This test was monitored for 10 minutes using the SMART video tracking system (Panlab S.L.U). Various swimming parameters were recorded and analyzed by smart software. The animals treated with the compositions showed reduced resting time and enhanced slow moving time, fast moving time, total moving time, path length of swimming and average velocity compared to the controlled treated animals as summarized in table 8.

Similarly, after 21 days of treatment, the grip strength of mice was measured by using Grip strength meter (UgoBasile, Italy). Animals were trained and habituated to the experimental environment and conditions for 5 days. Each mice was allowed to grasp the grasping bar and it was pulled back gently in a horizontal plane by tail with gradually increasing force till the pulling force overcomes the grip strength of the animal. The force applied at the moment when the mice leaves its grasp on the grasping bar was recorded as grip strength in grams. The animals supplemented with the compositions LI89032F3 or LI12522F2 or LI80020F3 showed improved grip strength compared to the animals treated with control or positive controls (L-Carnitine or Caffeine) as summarized in Table 9.

Hence, it is evident that supplementation of extracts or fractions derived from Sphaeranthus indicus, Coleus aromaticus, Cissus quadrangularis, Curcuma longa, Garcinia mangostana and Cinnamomum tamala and their compositions (LI12522F2, LI89032F3 and LI80020F3) can increase the energy levels and endurance potential.

The nitrite concentration in human endothelial culture supernatants from the cells treated with the test substances was measured in comparison with the control treated cell culture supernatants. Briefly, equal number of ECV304 human endothelial cells (1.5×10⁵) was plated in 35 mm culture dish. After attachment of the cells, the culture dishes were washed twice with Hank's Buffered Salt Solution (HESS) and the cells were treated with different concentrations of extracts and compositions in 1 ml □-MEM supplemented with 1% FBS for 4 h. The vehicle control cultures received 0.2% DMSO. The cell free culture supernatants were collected and nitrite content was estimated using Griess assay. Fifty micro liters of culture supernatants were mixed with equal volume of Griess reagent (a mixture containing 1:1 ratio of 0.2% naphthylenediaminedihydrochloride and 2% sulphanilamide in 5% phosphoric acid) in each well of a micro-titer plate and incubated further for 10 min in room temperature. The color development was measured at 550 nm in a microplate reader Spectra MaxM5 (Molecular devices, Sunnyvale, Calif.). Standard curves were constructed with known concentrations of sodium nitrite and the data is summarized in table 1.

The above nitrite concentration values (Table 1), clearly shows the synergistic efficacy of the compositions in enhancing nitrite concentration. For example, at 10 μg/ml concentration, the S. indicus extract (LI12500) and C. aromaticus extract (LI34103) exhibited 10.64% and −1.8% nitrite concentrations respectively. Whereas the composition 1 (LI12522F2), which contains 2:1 ratio of S. indicus extract (LI12500) and C. aromaticus extract (LI34103) exhibited 20.8% nitrite concentration. This nitrite concentration level in the cells treated with the compositions is higher than that in the cells treated with the individual components.

The Nitrate assay was conducted using composition-4 (LI12532F1) and individual extracts of S. indicus (LI12500), C. aromaticus (LI34103) and G. mangostana (LI80013). The composition-4 (LI12532F1) clearly shows the synergistic activity at both tested concentrations of 10 and 25 μg/ml. The results of this study showed that composition-4 (LI12532F1) exhibited greater enhancing nitrate concentration activity than the individual extracts. For example at 25 μg/ml concentration in the Table 2, S. indicus extract (LI12500), C. aromaticus extract (LI34103) and G. mangostana extract (LI80013) exhibited 5.08%, 21.55% and 109.32% nitrate concentration. Whereas the composition-4 (LI12532F1) exhibited 193.99% nitrate concentration at 25 μg/ml. The nitrate concentration enhancing activity with the composition-4 (LI12532F1) is higher than that the individual extracts.

The above nitrite concentration values (Table 3), clearly shows the synergistic efficacy of the composition-7 (LI89034F1) in enhancing nitrite concentration. For example, at 1 μg/ml concentration, C. quadrangularis (LI05704), C. longa (LI09703) and T. ammi (LI12304) exhibited −13.11%, 36.25% and 20.52% nitrite concentrations respectively. Whereas the composition-7 (LI89034F1), which contains 1:2:1 ratio of C. quadrangularis (LI05704), C. longa (LI09703) and T. ammi (LI12304) exhibited 79.10% nitrite concentration. This nitrite concentration level in the cells treated with the composition-7 (LI89034F1) is higher than that in the cells treated with the individual components. So the nitrate enhancing activity of composition-7 (LI89034F1) is higher than the individual extracts.

Cellular ATP content was measured in rat skeletal muscle cells using ATPlite assay kit (Perkin Elmer). Briefly, L6 rat skeletal muscle cells were grown in a 96 well plate in RPMI, supplemented with 10% FBS and 500 g/ml of penicillin-streptomycin at 37° C. with 5% CO2. After 16 h, media was replaced with fresh media containing independently Sphaeranthus indicus extract (LI12500) and its compositions (LI12522F2 and LI12532F1); Cissus quadrangularis extract (LI05704), and its compositions (LI89032F3 and LI89034F1; Garcinia mangostana extract (LI80013) and its composition (LI80020F3) in combination with Cinnamomum tamala extract (LI33603); Citrullus lanatus extract (LI/PD/151/01R1) and Ocimum sanctum extract (LI/PD/014/03R1) and incubated for 4 hours. The vehicle control cultures received only 0.2% DMSO. Thereafter, 50 μl cell lysis buffer was added to each well and incubated for 5 min under controlled shaking condition. The evaluation of ATP concentrations of different cell lysates so obtained were conducted following the method provided by the vendor (Perkin Elmer Life Sciences, Boston, Mass.). The standard wells contain various concentrations of ATP ranging from 10 μM to 0.15 μM. Fifty micro liters of substrate solution was added to each well and allowed to mix on a shaker for 15 min under dark condition. Finally, the luminescence intensity was measured in a microplate reader Spectra MaxM5 (Molecular devices, Sunnyvale, Calif.). ATP content in the cell lysates obtained from the cells treated with individual extracts or compositions was measured by plotting the luminescence intensities into the standard curve constructed from the known ATP concentrations. The cellular ATP index in the treated cultures was calculated by comparing the ATP content in the treated samples with the ATP content in the vehicle control cultures. The ATP content in the vehicle control cultures was considered as 100 percent. All treatment concentrations for each sample were treated in quadruplicate wells.

The ATPlite assay kit and the ATP concentration (%) data is summarized in Table 4. The data reveled that all the compositions showed an increase in the ATP content with a significant synergistic effect. The results of this study showed that composition of the extracts showed greater ATP concentration than the individual extracts. For example, at 10 pg/ml concentrations, the C. quadrangularis extract (LI05704) and C. longa extract (LI09703) exhibited 129.04% and 85.21% ATP concentration respectively. Whereas the composition 2 (LI89032F3), which contains 1:2 ratio of C. quadrangularis extract (LI05704) and C. longa extract (LI09703) exhibited 157.1% ATP concentration.

Cellular ATP content was measured in rat skeletal muscle cells using the extracts of S. indicus (LI12500), C. aromaticus (LI34103) and G. mangostana (LI80013). Table 5 shows the values of ATP content at 10 pg/ml concentration. The composition-4 (LI12532F1) containing S. indicus (LI12500), C. aromaticus (LI34103) and G. mangostana (LI80013) exhibited good synergistic activity with an increased ATP content of 153.01% at 10 pg/ml concentration. Whereas, the individual extracts showed lower activity than the composition with an ATP content of 86.93% for S. indicus (LI12500), 95.65% for C. aromaticus (LI34103) and 124.24% for G. mangostana (LI80013) at 10 pg/ml. This unexpected result clearly shows the synergistic activity of the composition-4 with an increased ATP concentration.

The results from ATP assay (Table 6), clearly shows the synergistic efficacy of the composition-7 (LI89034F1) in enhancing ATP concentration. For example, at 1000 pg/ml concentration, C. quadrangularis (LI05704), C. longa (LI09703) and T. ammi (LI12304) exhibited 105.25%, 119.46% and 144.94% ATP concentrations respectively. Whereas the composition-7 (LI89034F1), which contains 1:2:1 ratio of C. quadrangularis (LI05704), C. longa (LI09703) and T. ammi (LI12304) exhibited 158.57% ATP concentration. This ATP levels in the cells treated with the composition-5 is higher than that in the cells treated with the individual components. So the ATP increasing activity of composition-7 (LI89034F1) is higher than the individual extracts.

Protein synthesis enhancing efficiency of Sphaeranthus indicus extract (LI12500) and its compositions (LI12522F2 and LI12532F1) in combination with Coleus aromaticus extract (LI34103) as well as with Garcinia mangostana extract (LI80013); Cissus quadrangularis extract (LI05704), and its compositions (LI89032F3 and LI89034F1) in combination with Curcuma longa extract (LI09703) as well as with Trachyspermum ammi extract (LI12304); Garcinia mangostana extract (LI80013) and its composition (LI80020F3) in combination with Cinnamomum tamala extract (LI33603); Citrullus lanatus extract (LI/PD/151/01R1) and Ocimum sanctum extract (LI/PD/014/03R1) was assessed in L6 rat skeletal muscle cells. Equal number of L6 cells was grown in each well of 96 well cell culture plates. Next day, the cells were treated with various concentrations of the Sphaeranthus indicus extract, Coleus aromaticus extract, Cissus quadrangularis extract, Garcinia mangostana extract, Curcuma longa extract and Cinnamomum tamala extract; and their compositions LI89032F3, LI89034F1, LI12522F2, LI12532F1 and LI80020F3 and the treatment phase was continued till 72 h. The vehicle control culture well received only 0.2% DMSO. After the treatment period, cells were washed twice with phosphate buffered saline (PBS). Thereafter, the cells were lysed in 1% SDS. The protein content in the cell lysates was measured using BCA Protein Assay kit (Thermo Scientific). Bovine serum albumin at different concentrations ranging from 25 μg/ml to 0.78 ug/ml was used as the standard. The absorbance of the color reaction was read at 562 nm in a microplate reader Spectra MaxM5 (Molecular devices, Sunnyvale, Calif.). The protein content in the cell lysates was quantitatively measured by plotting the absorbance values into the standard curve constructed from the known protein concentrations in standard wells.

The dietary supplement compositions are screened for their protein synthesis efficiency in L6 rat skeletal muscle cells. All the tested compositions exhibited synergistic effect and more effective in increasing the content of protein in the skeletal muscle cell as summarized in Table 7. For example, at 1 ng/ml concentration, the G. mangostana extract (LI80013) and C. tamala extract (LI33603) exhibited 104.23% and 90.14% protein concentration respectively. Whereas the composition 3 (LI80020F3), which contains 1:2 ratio of G. mangostana extract (LI80013) and C. tamala extract (LI33603) exhibited 115.69% protein concentration.

Swiss albino mice were acclimatized for 5 days before initiation of the study. Healthy Swiss albino mice were selected and randomly divided (n=6) into different treatment groups. The animals were orally treated with vehicle or 150 mg/kg of LI89032F3 or LI12522F2 or LI80020F3 or 150 mg/kg of L-Carnitine or 10 mg/kg Caffeine for 21 days.

On day 21, one hour after the treatment the mice were forced to swim with a constant load (10% of its body weight attached to its tail) in an acrylic cylinder filled with water. This test was monitored for 10 minutes using the SMART video tracking system (Panlab S.L.U). Various swimming parameters were recorded and analyzed by smart software. Measured Swimming parameters include, resting time, slow moving time, fast moving time, total moving time, path length of swimming and average velocity. The results were expressed as mean±SEM and compared with control group to measure efficacy and were summarized in Table 8.

Swiss albino mice were administered with LI12522F2, LI89032F3, LI80020F3, Caffeine and L-Carnitine orally at the dose of 150 mg/kg of LI89032F3 or LI12522F2 or LI80020F3 or L-Carnitine or 10 mg/kg of Caffeine respectively, to evaluate the energy endurance and muscle strength potential of these compounds. The animal groups supplemented with the test items LI12522F2, LI89032F3, LI80020F3, L-Carnitine and standard drug caffeine showed a reduction in resting time (sec) and increase in distance traveled (mm), slow swimming time (sec), fast swimming time (sec) on day 21 of the study. The above observations indicate that the animals treated with LI12522F2, LI89032F3, LI80020F3, Caffeine and L-Carnitine were more active and energetic during 10 minutes of forced swimming period and could tend to swim either slow or fast most of the time rather than resting as compared to control group. The increase in percent fast swimming and swimming velocity in group on day 21 reveals that the treated animals tends to swim fast and covered longer distances in the shortest period of time after oral administration of LI12522F2, LI80020F3, LI89032F3 as compared to control group. Hence, the animals treated with these compositions LI12522F2, LI80020F3, LI8903 are more energetic. In addition, an improved energy the increase in distance traveled and reduced resting time indicate that the compositions LI12522F2, LI80020F3, LI89032F3 have higher endurance over the control.

Swiss albino mice were acclimatized for 5 days before initiation of the study. Healthy Swiss albino mice were selected and randomly divided (n=6) into different treatment groups. The animals were orally treated with vehicle or 150 mg/kg of LI89032F3 or LI12522F2 or LI80020F3 or 150 mg/kg of L-Carnitine or 10 mg/kg Caffeine for 21 days.

After 21 days of treatment Grip strength of mice was measured by using Grip strength meter (UgoBasile, Italy). Animals were trained and habituated to the experimental environment and conditions for 5 days. Each mice was allowed to grasp the grasping bar and it was pulled back gently in a horizontal plane by tail with gradually increasing force till the pulling force overcomes the grip strength of the animal. The force applied at the moment when the mice leaves its grasp on the grasping bar was recorded as grip strength in grams. Three trials were conducted on each animal and average grip strength was calculated. The results were expressed as mean±SEM and compared with control group and were summarized in Table 9.

Based on the data, it is obvious that animal group treated with compositions LI12522F2, LI80020F3 and LI89032F2 for 21 days exhibited relatively better grip strength when compared control.
