Tripterygium glycosides extract and its extraction process

Abstract

The process of extracting tripterygium glycosides includes the following steps: 1. extracting coarse tripterygium glycosides product through water extracting tripterygium powder, extracting with alcohol or alcohol aqua, merging the extracted solution, concentrating to volume content of alcohol not more than 20 %, organic solvent extracting and concentrating to obtain dry coarse tripterygium glycosides product; and 2. refining through dissolving the coarse product in organic solvent, adsorbing with adsorbent, filtering, eluting the filter cake, concentrating the eluted liquid, column chromatographic separation, eluting with organic solvent, and concentrating the eluted liquid to obtain dry product. The process has simple operation, low cost, short production period, less environmental pollution, and easy application in industrial production, and the product has high effective component content and high pharmaceutical effect.
