Abstract A novel bioside, β-(3′,4′-dihydroxyphenyl)ethyl- O -α- L -rhamnopyranosyl(1 → 3)-D-glucopyranoside, was obtained from the secondary roots of Harpagophytum procumbens . It is accompanied by the known iridoid glucosides harpagoside, procumbide, and its 6′- O -p-coumaroyl ester, and phenolic glycosides, acteoside and isoacteoside, the latter pair being obtained from H. procumbens for the first
摘要 从Harpagophytum procumbens 的次生根中获得了一种新型生物苷β-(3',4'-二羟基苯基)乙基-O-α-L-吡喃鼠李糖基(1→3)-D-吡喃葡萄糖苷。它伴随着已知的环烯醚萜苷 harpagoside、procumbide 及其 6'-O-p-香豆酰酯,以及酚糖苷、acteoside 和 isoacteoside,后者对首次从 H. procumbens 中获得。这些代谢物的结构通过高分辨率 NMR 研究进行了区分,而生物苷的结构也得到了合成的支持。
