A New Triterpenoid from Gymnema sylvestre and its Allelopathic Activity

A new triterpenoid (1) and four known compounds (2 –5) were isolated fromGymnema sylvestre. The structure of compound1 was elucidated as (3β,16β,22α)-22-benzoyloxy-16,23,28,29-tetrahydroxyolean-12-en-3-yl-O-β-D-glucopyranosiduronic acid by spectroscopic data (1H,13C NMR, HMBC, HSQC, COSY, and NOESY). Additionally, compound1 presented allelopathic activity on the growth of lettuce at 100 μM.
