[Studies on the constituents in rhizome of Homalomena occuta].

OBJECTIVE

Bio-active constituents were expected to abstain from Homalomena occuta.

METHODS

Extracts from the plant with 95% alcohol were distributed by several solvents and isolated via column chromatography on silica and Saphadex 20-LH gel.

RESULTS

Thirteen compounds were isolated from this plant. Among them seven natural products were identified via spectral methods as beta-stigmastol(H1) beta-D-Glucopyranoside(3)- stigmast-5-en-3-yl(H2); oplodiol(1); oplopanone(2); homalomenol(3); bullatantriol(4); 1 beta, 4 beta, 7 alpha-trihydroxyeudesmane(5).

CONCLUSION

All these compounds were isolated from this plant for the first time.
