To study the bioactive constituents from the flower of Castanea mollissima Blume.
Compounds were isolated and purified by column chromatography on silica gel and polyamide. Structures were determined by various spectroscopic data,including UV, IR, 1H and 13CNMR, EIMS and FABMS, 1H-13C-COSY and HMBC.
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]-alpha-D-mannopyranoside (1) and kaempferol-3-O-[6", 4"-di-(E)-p-coumaroyl]-alpha-D-mannopyranoside (2).
Compounds 1 and 2 are new compounds, named castanoside A and B respectirely.
研究板栗花中的生物活性成分。
通过硅胶柱色谱和聚酰胺柱色谱对化合物进行分离和纯化。利用紫外光谱(UV)、红外光谱(IR)、核磁共振氢谱(1H NMR)、核磁共振碳谱(13C NMR)、电子轰击质谱(EIMS)、快原子轰击质谱(FABMS)、氢-碳化学位移相关谱(1H-13C-COSY)和异核多键相关谱(HMBC)等多种光谱数据确定结构。
从95%乙醇提取物的乙酸乙酯部位分离得到两个化合物,其结构分别鉴定为山柰酚-3-O-[6"-(E)-对香豆酰基]-α-D-甘露吡喃糖苷(1)和山柰酚-3-O-[6",4"-二-(E)-对香豆酰基]-α-D-甘露吡喃糖苷(2)。
化合物1和2为新化合物,分别命名为栗苷A和栗苷B。
