A furostanol saponin mixture and a known phytoecdysteroid were isolated from the roots of Helleborus orientalis Lam. Their structures were established as 26-[(β-D-glucopyranosyl)oxy]-22α-hidroxyfurosta-5,25(27)-dien-1β,3β,11α-triol (1a), 26-[(β-D-glucopyranosyl)oxy]-22α-methoxyfurosta-5,25(27)-dien-1β,3β,11α-triol (1b), and 20-hydroxy-β-ecdyson-3-O-β-D-glycoside (2). Acid hydrolysis of 1a,b gave (1β,3β,11α,22α)-22,26-dimethoxyfurosta-5,25(27)-dien-1,3,11-triol (aglycone 1) and of 2 gave 20-hydroxy-β-ecdyson (aglycone 2). Their structures were elucidated by spectral analysis.
一种呋喃甾醇皂苷混合物和一种已知的植物蜕皮甾醇从东方楠木根中分离出来。它们的结构被确定为 26-[(β-D-吡喃葡萄糖基)氧基]-22α-hidroxyfurosta-5,25(27)-dien-1β,3β,11α-triol(1a)、26-[(β-D-glucopyranosyl)oxy]-22α-methoxyfurosta-5,25(27)-dien-1β,3β,11α-triol (1b), and 20-hydroxy-β-ecdyson-3-O-β-D-glycoside (2).酸水解 1a,b 可得到 (1β,3β,11α,22α)-22,26-二甲氧基呋喃甾-5,25(27)-二烯-1,3,11-三醇(缩酮 1),水解 2 可得到 20-羟基-β-ecdyson(缩酮 2)。通过光谱分析阐明了它们的结构。
