Preparation method for determining effective part of plum-leaf crab by taking biological activity as guidance

Номер: CN116036160A
Принадлежит:

The invention relates to a preparation method for determining effective parts of malus spectabilis fruits by taking biological activity as guidance. According to the method, crabapple is taken as a raw material, pretreatment, soaking, purification and concentration are carried out, a high performance liquid chromatography technology is combined, a reversed-phase high performance liquid chromatography technology is used for segmentation, antioxidant biological activity (DPPH free radical scavenging) and anti-inflammatory activity (COX-2 enzyme inhibitor) are taken as guidance, biological activity research is carried out on the crabapple, and rapid, efficient and high-purity crabapple is realized. The effective part of the plum-leaf crab is efficiently prepared. The method has the advantages that the operation is convenient, the conditions are controllable, the effective main components in the plum-leaf crab are convenient to quickly distinguish and confirm, and the problems that the segmentation ...

Method for extracting and purifying artemisia rupestris medicinal material

Номер: CN116392517A
Принадлежит:

The invention discloses a method for extracting and purifying an artemisia rupestris medicinal material. The method comprises the following steps: by taking an artemisia rupestris medicinal material as a raw material, crushing the whole artemisia rupestris herb, heating, refluxing and extracting by using an ethanol solution, concentrating, and purifying by using HPD300 macroporous resin to obtain the purified part of the artemisia rupestris medicinal material. In the extraction and purification process, 11 chemical components such as rupestonic acid are used as evaluation indexes, weights are given to the indexes by using an entropy weight method, and comprehensive scores are calculated to screen and optimize process parameters. According to the method, the extraction and purification process is optimized by taking clear active ingredients as targets, the content of the active ingredients is effectively increased, and the method is simple in process, easy to operate, low in equipment requirement ...
