【摘要】 从火炭母(PolygonumchinenseLinn.)中分离获得了12个化合物。通过光谱分析,分别鉴定为丁香酸(1)、芹菜素(2)、3,3’-二甲基鞣花酸(3)、没食子酸(4)、原儿茶酸(5)、异鼠李素(6)、咖啡酸(7)、槲皮素(8)、木犀草素(9)、没食子酸甲酯(10)、广寄生苷(11)和3,4,8,9,10-pentahydroxy-dibenzo[b,d]pyran-6-one(12)。除4和8外,其余化合物均为首次从火炭母中分离得到。更多还原

【Abstract】 Twelve chemical constituents were isolated from Polygonum chinense Linn. On the bases of spectral data, they were identified as syringic acid (1), apigenin (2), 3,3’-di-O-methylellagic acid (3), gallic acid (4), protocatechuic acid (5), isorhamnetin (6), caffeic acid (7), quercetin (8), luteolin (9), gallicin (10), avicularin (quercetin-3-O-α-L-arabinofuranoside)(11) and 3,4,8,9,10-pentahydroxy-dibenzo [b,d]pyran-6-one (12). All these compounds except 4 and 8 were reported from the species for the first time.更多还原
