Abstract


From the ethyl acetate extract of the leaves of Desmodium gangeticum collected in Me Linh, Ha Noi, we isolated 5 compounds including luteolin (1), luteolin tetramethyl ether (2),  N,N-dimethyl tetradecane-1-amin (3), D-pinitol (4)  and stigmasterol (5). In which, luteolin (1) was isolated from Desmodium gangeticum for the first time, luteolin tetramethyl ether (2) and  N,N-dimethyl tetradecane-1-amin (3) were first isolated from genus Desmodium. Their structures were determined by 1D and 2D NMR spectra.
