【Abstract】 Aim To study the bioactive constituents from the flower of Castanea mollissima Blume. Methods Compounds were isolated and purified by column chromatography on silica gel and polyamide.Structures were determined by various spectroscopic data,including UV, IR, 1 H and 13 CNMR, EIMS and FABMS, 1 H 13 C COSY and HMBC. Results Two compounds were isolated from the ethyl acetate fraction of 95% ethanol extract and the structures were elucidated as kaempferol 3 O [6″ ( E ) p coumaroyl] α D mannopyranoside (1) and kaempferol 3 O [6″,4″ di ( E ) p coumaroyl] α D mannopyranoside (2). Conclusion Compounds 1 and 2 are new compounds,named castanoside A and B respectirely.更多还原
