Structure of triterpene saponins from the roots ofGlycyrrhiza echinata
On the basis of a physicochemical study of the saponins ofGlycyrrhiza echinata L., their molecular weights have been determined. It has been found that the two saponins are biosides of macedonic acid (saponin A) and echinatic acid (saponin B), the carbohydrate moieties of which contain L-rhamnose and D-glucuronic acid.
In both saponins, the L-rhamnose is bound directly to the aglycones.
