Problems solved by technology

[0008] However, although researchers have developed many techniques for extracting schisandrin B, there are more or less problems in the existing extraction or separation techniques, such as large amount of solvent, long extraction time, high extraction cost, and low extraction rate etc. It can be seen that these processes still need to be improved urgently to meet the ultimate goal of industrial production and application, that is, to achieve maximum utilization of materials and high yield of products

Abstract

The invention relates to a combined type method for extracting schisandrin b from fructus schisandrae. The method comprises the steps of pretreatment of raw materials, preparation of compound extractant, extraction and separation and purification; the compound extractant formed by appropriate ionic liquid, assistant and hexadecyl trimethyl ammonium bromide is adopted, solid sodium carbonate is added for auxiliary extraction, and besides, microwaves and expanded solvent are adopted for complementary extraction, therefore, the method for extracting the schisandrin b from the fructus schisandrae with high yield is achieved finally, the material utilization rage is improved, waste discharge and environment pollution, caused by a great amount of organic solvents, are avoided, and wide industrial application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of extracting active ingredients of medicines from natural plants. More specifically, the present invention relates to a compound method for effectively extracting schisandrin B from Schisandra chinensis, which has good prospects for industrial application. Background technique [0002] Schisandra chinensis is the mature fruit of the Magnoliaceae plant Schisandra chinensis, which contains a variety of active ingredients, such as lignans, triterpenes, sesquiterpenes, organic acids, volatile oils, etc. It has extremely high nutritional and medicinal value, and exhibits It has a variety of pharmacological effects on the nervous system, digestive system and cardiovascular system. In recent years, as an important component of Schisandra lignans, Schizandrin B has attracted much attention. It has a high content in lignans and a wide range of biological activities. Alanine aminotransferase, anti-cancer, antibacte...
