广藿香大极性化学成分的研究

从广藿香(Pogostemon cablin (Blance)Benth.)地上部分乙醇提取物的正丁醇萃取部位分离得到13个化合物.通过光谱和波谱分析,分别鉴定为:芹菜素(1)、3,5,4'-三羟基-7-甲氧基黄酮(2)、3,5-二羟基_4',7-二甲氧基黄酮(3)、Apigenin 7-galacturonide(4)、Apigenin 7-(O-methylghacuronide)(5),Luteolin 7-O-(6-O-methyl-β-D-glucuronopyranoside)(6),4',5-二羟基-3',7-二甲氧基二氢黄酮(7)、Quercetha-7-β-D-ghcoside(8),3,23-Dihydroxy-12-oleanen-28-oic acid(9)、Syringaresinol-β-D-glucoside(10),毛蕊花糖苷(11)、列当苷(12)、紫葳新苷(13),化合物2～13均为首次从该植物中分离得到.

Strong Polarity Components of Pogostemon cablin (Blance) Benth.

Thirteen compounds were isolated from n-butanol extraction of ethanol extract of the aerial parts of Pogostemon cablin (Blance) Benth. On the basis of spectral data,they were identified as apigenin (1),3,5,4'-Trihydroxy-7-methoxyflavone (2),3,5-Dihydroxy-4',7-dimethoxyflavone (3),apigenin 7-galacturonide(4),apigenin 7-(O-methylghcuronide)(5),luteolin 7-O-(6-O-methyl-β-D-glucuronopyranoside)(6),4',5-Dihydroxy-3',7-dimethoxyflavanone (7),quercetin-7-β-D-glucoside (8),3,23-dihydroxy-12-oleanen-28-oic acid (9),syringaresinolβ-D-glucoside(10),verbascoside(11),orobanchoside(12),campneoside Ⅰ(13).Compounds 2～13 were isolated from the plant for the first time.
