摘要: 秀丽莓(Rubus amabilis Focke)为蔷薇科悬钩子属植物,系常用藏药,已有1300多年历史。本实验从其茎中分离了8个化合物,通过波谱法和理化性质分别鉴定为:4-乙酰氧基-3-甲氧基苯甲酸(1)、2-O-β-D-吡喃葡萄糖基-6-羟基苯甲酸(2)、香草酸(3)、 白藜芦醇(4)、2,6-二甲氧基-4-羟苯基-1-O-β-D-吡喃葡萄糖苷(5)、反式-4-羟基桂皮酸(6)、咖啡酸(7)及没食子酸(8)。其中1为新天然产物,化合物2~7均为首次从该植物中分离得到。

Abstract: The constituents of Rubus amabilis were isolated and purified by silica gel column chromatography,Sephadex LH-20,macroporous adsorption resin and TLC.The structures of the purified compounds were elucidated on the basis of spectral data and physiochemical properties.Eight compounds were isolated and their structures were identified as:4-acetoxy-3-methoxybenzoic acid (1), 2-(β-D-glucopyranosyloxy)-6-hydroxybenzoic acid (2), vanillic acid (3), resveratrol (4), 2,6-dimethoxy-4-hydroxyphenol-1-O-β-D-glucopyranoside (5),trans-4-hydroxy cinnamic acid (6),caffeic acid (7) and gallic acid (8).Compound 1 was a new natural product.Compounds 2-7 were isolated from Rubus amabilis for the first time.

Key words: Rubus amabilis Focke, Rosaceae;phenolic compounds;structural elucidation
