目的:研究白英Solanum lyratum Thunb.全草的化学成分。方法:采用正相、反相硅胶柱色谱及Sephadex LH-20凝胶柱色谱和制备薄层等手段进行分离纯化, 通过波谱解析和理化鉴别进行结构鉴定。结果:分离鉴定出 11个化合物, 分别为薯蓣皂苷元(1)、剑麻皂苷元(2)、丁香醛(3)、丁香酸(4)、对羟基苯甲醛(5)、莨菪亭(6)、N-顺式阿魏酰基酪胺(7)、β-谷甾醇(8)、胡萝卜苷(9)、赤藓糖醇(10)、甘露醇(11)。结论:化合物 7 为首次从茄科植物中分离得到, 化合物10、11为首次从茄属植物中分离得到, 化合物 3-5 为首次从该植物中分离得到。
Objective: To study the chemical constituents of Solanum lyratum Thunb. Methods: The constituents were isolated and purified by normal phase and reversed phase silica gel column chromatography, Sephadex LH-20 column chromatography and preparative TLC. The structures were identified by spectral analysis and physical and chemical identification. RESULTS: Eleven compounds were isolated and identified as diosgenin (1), tigogenin (2), syringaldehyde (3), syringic acid (4), p-hydroxybenzaldehyde ), N-cis-feruloyl tyramine (7), β-sitosterol (8), daucosterol (9), erythritol (10) and mannitol (11). Conclusion: Compound 7 was isolated from solanaceous plants for the first time. Compounds 10 and 11 were isolated from solanum for the first time. Compounds 3-5 were isolated from this plant for the first time.
