Hodulcine

Hodulcine (or hoduloside) are glycosides (dammarane-type triterpenes) which are isolated from the leaves of "Hovenia dulcis Thunb." ("Rhamnaceae") also known as Japanese Raisin Tree.
Several glycosides homologue have been found in this plant and although hoduloside 1 exhibits the highest anti-sweet activity, it is less potent than gymnemic acid 1.
