ABSTRACT
@#To study the chemical constituents of petroleum ether extract from the stems and leaves of Humulus scandens (family of Moraceae), fifteen compounds were isolated from the stems and leaves of H.scandens by silica gel, Sephadex LH-20, ODS, and preparative HPLC chromatography.The structures were identified by physicochemical data and spectroscopic method as tectochrysin (1), chrysin (2), 5-hydroxy-3, 4'', 6, 7-tetramethoxyflavone (3), (2S)-5-hydroxy-7, 8-dimethoxyflavanone (4), imperatorin (5), phellopterin (6), ethyl 4-hydroxy-3-(3''-methyl-2''-butenyl)benzoate (7), p-hydroxy-phenylpropionic acid (8), ethyl p-hydroxycinnamate (9), p-hydroxybenzaldehyde (10), anofinic acid (11), 5,6-dehydrokavain (12), physcion (13), olean-12-ene-3,?11-dione (14) and ergosta-4, 6, 8 (14), 22-tetraen-3-one (15), respectively.All compounds were isolated from this plant for the first time.
