Abstract

Five novel phenolic glycosides, adenophorasides A (1), B (2), C (3), D (4), and E (5), were isolated from commercial Adenophora roots, together with vanilloloside (6), 3,4-dimethoxybenzyl alcohol 7-O-beta-D: -glucopyranoside (7), and lobetyolin (8). The structures of the new compounds (1-5) were characterized as 4-hydroxy-3-methoxyphenylacetonitrile 4-O-beta-D: -glucopyranoside (1), 4-hydroxy-3-methoxyphenylacetonitrile 4-O-beta-D: -glucopyranosyl-(1-->6)-beta-D: -glucopyranoside (2), 4-hydroxy-3-methoxyphenylacetonitrile 4-O-alpha-L: -rhamnopyranosyl-(1-->6)-beta-D: -glucopyranoside (3), 4-hydroxyphenylacetonitrile 4-O-beta-D: -glucopyranosyl-(1-->6)-beta-D: -glucopyranoside (4), and 4-hydroxy-3-methoxybenzyl alcohol 4-O-beta-D: -glucopyranosyl-(1-->6)-beta-D: -glucopyranoside (5), respectively, by means of spectroscopic and chemical analyses.

摘要

从市售党参根中分离得到了 5 个新的酚糖苷,分别为腺诺索苷 A(1)、B(2)、C(3)、D(4)和 E(5),以及香草醇苷(6)、3,4-二甲氧基苄醇 7-O-β-D:-吡喃葡萄糖苷(7)和 lobetyolin(8)。新化合物(1-5)的结构分别鉴定为 4-羟基-3-甲氧基苯乙腈 4-O-β-D:-吡喃葡萄糖苷(1)、4-羟基-3-甲氧基苯乙腈 4-O-β-D:-吡喃葡萄糖基-(1'->6)-β-D:-吡喃葡萄糖苷(2)、4-羟基-3-甲氧基苯乙腈 4-O-α-L:-鼠李吡喃糖苷基-(1'->6)-β-D:-吡喃葡萄糖苷(3)、4-羟基苯乙腈 4-O-β-D:-吡喃葡萄糖基-(1'->6)-β-D:-吡喃葡萄糖苷(4)和 4-羟基-3-甲氧基苄醇 4-O-β-D:-吡喃葡萄糖基-(1'->6)-β-D:-吡喃葡萄糖苷(5),通过光谱和化学分析。
