摘要:除了之前报道过的苯基丁酮葡萄糖苷,即 Lindleyin (7),Isolindleyin (8) 和 4-(4'-羟基苯基)-2-丁酮 4'-O-β-D-Glucopyranoside (9),我们还从一种优质大黄(商品名: )中分离出了三种新的相关化合物(1,2 和 3).根据化学和光谱数据,1-3 的结构被确定为 4-(4'-羟基苯基)-2-丁酮 4'-O-β-D-(2",6"-Di-O-Galloyl)-吡喃葡萄糖苷 (1),4-(4'-Hydroxyphenyl)-2-Butanone 4'-O-β-D-(2"-O-Galloyl-6"-O-Cinnamoyl)-Glucopyranoside (2) 和 4-(4'-Hydroxyphenyl)-2-Butanone 4'-O-β-D-(2"-O-Galloyl-6"-O-P-Coumaroyl)Gluocopyranoside (3).此外,还新分离出了 3,4',5-三羟基二苯乙烯 4'-O-β-D-(2"-O-吡咯酰基)-吡喃葡萄糖苷(4),没食子酸 3-O-β-D-吡喃葡萄糖苷(5)和没食子酸 4-O-β-D-吡喃葡萄糖苷(6).
