Problems solved by technology

Existing studies have shown that the pyripolic acid C isolated from Poria cocos has anti-tumor and immune-enhancing effects. Most of the existing methods for isolating and purifying pyripolic acid C use traditional atmospheric silica gel chromatography, and the general yield is low. Poor purity, weak targeting, unable to meet the needs of mass production

Abstract

The invention discloses a method for preparing polyporenic acid C from Poria cocos. The method comprises the following steps: with Poria cocos as a raw material, carrying out crushing, extraction, filtration, concentration and extraction, subjecting an extract to coarse separation through vacuum liquid chromatography so as to prepare a crude polyporenic acid C product, subjecting the crude polyporenic acid C product to separation and purification through a dynamic axial compression chromatography technology so as to prepare a pure polyporenic acid C product, and carrying out recrystallizationso as to obtain the polyporenic acid C. Compared with a conventional processing method, the method provided by the invention has the advantages of high work efficiency, low cost of a solvent for coarse extraction, high separation precision for a filling material, reusability, low cost of a solvent for chromatography, relatively-low pollution to the environment, high purity of the polyporenic acidC, etc., and is applicable to industrial preparation.

Description

technical field [0001] The invention belongs to the field of modernization of traditional Chinese medicines, and in particular relates to a method for preparing pigolic acid C from poria cocos. Background technique [0002] Poria cocos, also known as Yuling, Fuling, Wanlinggui, and Poria cocos, is the sclerotia of the fungus Poriacocos (Schw.) Wolf of the family Polybacteriaceae. It is used for edema, oliguria, dizziness and palpitation due to phlegm and retention, deficiency of the spleen, lack of food, loose stool and diarrhea, restlessness, palpitation and insomnia. [0003] Modern pharmacological studies have shown that Poria cocos has the functions of enhancing immunity, delaying aging, anti-tumor, anti-virus, and anti-inflammation. At present, a variety of chemical components have been isolated from Poria cocos, mainly including polysaccharides and terpenoids, in addition to steroids, fatty acids, proteins, adenine, amino acids and various inorganic elements. Existin...
