Method for extracting fucosterol from alga

Abstract

The invention discloses a method for extracting fucasterol from seaweed. Said invention adopts the techniques of chromatography and crystallization, etc to quickly extract fucosterol from natural material seacoeed, and has the advantages of rapid separation speed, low separation cost and rich and easily-available raw material and characterized by high product purity (purity is greater than 90%), regular crystal (white needle crystal) and small melting point range of 113-114 deg.C, etc. Said invention can be suitably used as fucosterol slandard prduct and raw material for making medicine. In the technological process related to said invention the single silica-gel column chromatographic separation method is adopted, the product can be crystallized by adopting one-ste process and monobasic solvent (ethyl alcohol), said product has no any toxic harms.

Description

technical field

[0001] The invention relates to the field of biochemistry or biochemical technology, in particular to a method for extracting fucosterol from seaweed. Background technique

[0002] Fucosterol is a kind of phytosterol, which has very important physiological functions, such as maintaining the stability of biological internal environment, controlling the metabolism of glycogen and minerals, and regulating stress response. In medicine, fucosterol can inhibit carcinogenesis induced by chemical carcinogens, and has the function of preventing and treating cancer. It can also be used as an important source of steroid drugs, and can be used as a raw material for the synthesis of male hormones, female hormones, and adrenal cortex hormones. In addition, fucosterol itself also has estrogen-like effects, and feeding chicks with fucosterol can significantly reduce blood cholesterol. Moreover, fucosterol can promote the absorption of calcium by the small intestine and ren...
