Preparation method of high-purity capsorubin diester and capsorubin

Номер: CN103724247A
Автор: GAO WEI, GU YANCHAO, QIAN JIANRUI, WANG LEI, XU MENG
Принадлежит:

The invention discloses a preparation method of high-purity capsorubin diester and capsorubin. The preparation method comprises the process steps of (1) preparing capsorubin into a mixed solution by using an organic solvent; (2) sampling the mixed solution to a silica gel chromatographic column, and collecting a capsorubin-diester-containing eluent through gradient elution by using a mixed solvent system of normal hexane and ethyl acetate as a mobile phase; (3) evaporating and concentrating at vacuum and removing a solvent in the eluent, and recrystallizing to obtain capsorubin diester; (4) saponifying the eluent in step (2) or the capsorubin diester in step (3) by using an alkaline alcoholic solution, and removing a solvent from saponification liquid to obtain a capsorubin monomer; and (5) recrystallizing the capsorubin monomer to obtain a capsorubin crystal. The method is high in product purity, stable in technology and good in repeatability, and can be used for separately preparing the ...

Homogeneous composite solvent and method for preparing dephenolized cotton seed protein by one-step process

Номер: CN104177471A
Автор: LU QINGGUO, LIAN YUNHE, SONG WEIGUANG, QIAN JIANRUI, WANG YING, YUAN XINYING
Принадлежит:

The invention discloses a homogeneous composite solvent and method for preparing dephenolized cotton seed protein by a one-step process. The homogeneous composite solvent is mainly composed of low-molecular ether or low-molecular ester and low-molecular alcohol in a volume ratio of (2-147):3, and all the components are mutually soluble. The composite solvent adopts the homogeneous mutually-soluble system composed of the low-molecular ether or low-molecular ester, low-molecular alcohol and water to perform one-step extraction on the cotton seed; and under the interactions among the solvents, the grease, gossypol and aflatoxin are effectively extracted, thereby lowering the protein denaturation in the extraction process and enhancing the protein quality. The solvent can be volatilized from the linter pulp more and recovered more easily, thereby greatly lowering the solvent consumption. Therefore, the composite solvent can effectively enhance the product extraction rate of the one-step extraction ...
