Gymnemic acids are glycosides isolated from the leaves of ''Gymnema sylvestre'' (Asclepiadaceae). Gymnemic acids like ziziphin and hodulcine are anti-sweet compounds, or sweetness inhibitors. After chewing the leaves, solutions sweetened with sucrose taste like water. More than 20 homologues of gymnemic acid are found in the leaves.〔AD kinghorn and CM Compadre. Less common high-potency sweeteners. In Alternative Sweeteners: Second Edition, Revised and Expanded, L O'Brien Nabors,Ed., New York, 1991. ISBN 0-8247-8475-8〕 Gymnemic acid 1 has the highest anti-sweet properties. It suppresses the sweetness of most of the sweeteners including intense artificial sweeteners such as aspartame and natural sweeteners such as thaumatin, a sweet protein. The anti-sweet activity is reversible, but sweetness recovery on the tongue can take more than 10 minutes.〔(Kurihara, Y. 1992.
