[Studies on chemical constituents of Salacia prinoides].

OBJECTIVE

To study the chemical constituents of Salacia prinoides.

METHODS

The chemical constituents were isolated and purified with various column chrmoatography and the structures were elucidated by chemical evidence and spectral analysis.

RESULTS

Sixteen compounds,including seven triterpenes : lupeol (1), Lup-20(29)-en-3beta,30-diol (2), 30-Hydorxylup-20 (29) -en-3-one (3), 3, 22-dioxo-29-normoretane (4), Ursolid acid (5), beta-Sitosterol (6), beta-Daucosterol (7); Four flavanoids: Quercetin (8), Quercet-in-3', 4'-dimethylether (9), Isorhamnetin (10), Kaempferol-4'-methylether (11); Three Phenolic acids:Gallic acid (12), Ethyl gallate (13), Egallic acid (14); Two Fatty series: Hentriacontanol (15), Hentriacontan-12-ol (16) were obtained from the titled plant.

CONCLUSIONS

-4, 8 - 13 are isolated from the genus for the first time, 5, 14 -16 are isolated from the plant for the first time.
