Method for manufacturing an aqueous solution containing triterpene acid, an aqueous solution containing triterpene acid and its application

摘要

Preparation of aqueous triterpenic acid solution comprises (a) providing a basic aqueous triterpenic acid containing solution; and (b) neutralizing the pH value of the basic triterpenic acid containing solution through addition of acid aqueous solution in the presence of stabilizing additive. An independent claim is included for an aqueous solution of a plant extract, exhibits at least a triterpenic acid and/or its derivatives, where the solution shows a pH of 5-9 in the presence of aqueous-physiological solution of triterpenic acid stabilized additive, which shows triterpenic acid content of more than 1 mu g/ml, where the stabilized additive is polysaccharide. ACTIVITY : Cytostatic. MECHANISM OF ACTION : None given.
