Phenylpropanoid Glycosides from Brandisia hancei

从云南民间药用植物来江藤 (BrandisiahanceiHook .f.)的全草中分离到 1 0个化合物 ,分别鉴定为 3,4 二羟基苯乙醇基 O α L 鼠李吡喃糖基 (1→ 3) β D (4 O 咖啡酰基 ) 半乳吡喃糖苷 (1 ) ,3,4 二羟基苯乙醇基 O α L 鼠李吡喃糖基 (1→ 3) β D (2 O 乙酰基 4 O 咖啡酰基 ) 半乳吡喃糖苷 (2 ) ,acteoside (3) ,2′ acetylacteoside (4 ) ,poliumoside (5 ) ,2′ acetylpoliumoside(6 ) ,mussaenoside (7) ,luteolin 7 O β D glucoside (8) ,luteolin (9)和mannitol (1 0 )。化合物 1- 6为苯丙素配糖体成分 ,其中化合物 2为新化合物 ,化合物 1为首次从该属植物中获得。

A new phenylpropanoid glycoside,3,4-dihydroxyphenethoxy-O-α-L-rhamnopyranosyl-(1→3)-β-D-(2-O-acetyl-4-O-caffeoyl)-galactopyranoside(2),together with five other phenylpropanoid glycosides (1,3,4,5,6) was isolated from the whole plants of Brandisia hancei .Their structures were determined by spectral and chemical methods.
