OBJECTIVE: To investigate the chemical constituents of the bulbs of Bolbostemma panicultum. METHOD: 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. RESULT: 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). CONCLUSION: I-VIII were obtained from this plant for the first time; VI and VIII are new compounds. |
