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。 Rubus amabilis (Rubus amabilis Focke) Rosaceae Rubus, commonly used Tibetan medicine, has more than 1300 years of history. In this experiment, eight compounds were isolated from their stems and identified as 4-acetoxy-3-methoxybenzoic acid (1), 2-O-β-D-glucopyranose Hydroxybenzoic acid (2), vanillic acid (3), resveratrol (4), 2,6-dimethoxy-4-hydroxyphenyl-1-O-β-D-pyran Glucoside (5), trans-4-hydroxycinnamic acid (6), caffeic acid (7) and gallic acid (8). Among them, 1 was a new natural product, and compounds 2 ~ 7 were isolated from this plant for the first time.
