Hodulcines (or hodulosides) are a group of glycosides of dammarane-type triterpenes which are isolated from the leaves of Hovenia dulcis Thunb. ( Rhamnaceae ), also known as Japanese raisin tree. Several glycoside homologs have been found in this plant, including hoduloside I, which exhibits anti-sweet activity, but is less potent than gymnemic acid 1. [1]
