Abstract

The invention relates to a method for extracting triterpenoids in dracocephalum moldavica. The extract of total triterpenes in dracocephalum moldavica is immediately obtained through concentration, hot water washing, alkali dissolving, acid precipitation, decolorization and purification by adsorption column chromatography of extracting solution of ethanol in dracocephalum moldavica. The content of total triterpenes in dracocephalum moldavica extract is not lower than 50% and the total content of oleanolic acid and ursolic acid is not lower than 80% of the content of total triterpenes. The extract of total triterpenes in dracocephalum moldavica has the effect of protecting livers and can be used for preparing drugs for liver diseases.

Description

technical field [0001] The invention relates to a total triterpene extract of Cymbidium orchid and its preparation method and application, belonging to the field of natural medicines.
