OBJECTIVE
To investigate the chemical constituents of the bulbs of Bolbostemma panicultum.
METHODS
The compounds were isolated by column chromatography on silica gel, C18, Sephadex LH-20 separately and their structures were elucidated by chemical and spectroscopic technologies.
RESULTS
Eight compounds were isolated and identified as maltol(I), emodin(II), cucurbitacin B(III), cucurbitacin E(IV), stigmasta-7, 22, 25-triene-3-ol(V), stigmasta-7, 22, 25-triene-3-nonadecanoic acid ester(VI), stigmasta-7, 22, 25-triene-3-O-beta-D-glucopyranoside(VII), stigmasta-7, 22, 25-triene-3-O-beta-D-(6'-palmitoyl) glucopyranoside(VIII).
CONCLUSIONS
I-VIII were obtained from this plant for the first time; VI and VIII are new compounds.
