火炭母化学成分的研究

Identification of Chemical Constituents from Polygonum chinense Linn.

摘要:

从火炭母中分离获得了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-6H-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。

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 -6H-dibenzo [b,d]pyran-6-one (12). All these compounds except 4 and 8 were reported from the species for the first time.
