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-β-d-glucopyranoside (7), and lobetyolin (8). The structures of the new compounds (1–5) were characterized as 4-hydroxy-3-methoxyphenylacetonitrile 4-O-β-d-glucopyranoside (1), 4-hydroxy-3-methoxyphenylacetonitrile 4-O-β-d-glucopyranosyl-(1→6)-β-d-glucopyranoside (2), 4-hydroxy-3-methoxyphenylacetonitrile 4-O-α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside (3), 4-hydroxyphenylacetonitrile 4-O-β-d-glucopyranosyl-(1→6)-β-d-glucopyranoside (4), and 4-hydroxy-3-methoxybenzyl alcohol 4-O-β-d-glucopyranosyl-(1→6)-β-d-glucopyranoside (5), respectively, by means of spectroscopic and chemical analyses.
从商业化的腺胡椒根中分离出了五种新的酚苷,即腺胡椒苷 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-glucopyranoside (7) 和叶乙醇苷 (8)。新化合物(1-5)的结构表征为 4-羟基-3-甲氧基苯乙腈 4-O-β-d-吡喃葡萄糖苷(1)、4-hydroxy-3-methoxyphenylacetonitrile 4-O-β-d-glucopyranosyl-(1→6)-β-d-glucopyranoside (2)、4-hydroxy-3-methoxyphenylacetonitrile 4-O-α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside (3)、通过光谱和化学分析,分别得出了 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)。
