To investigate the chemical constituents in 95% alcohol extract of Solanum lyratum.
The compounds were isolated by column chromatography over silica gel, and purified by Sephadex LH-20 column chromatography and preparative TLC. The structures were elucidated on the basis of physicochemical properties and spectral data.
Eleven compounds were isolated and identified as: formononetin (1), vanillic acid (2), genistein (3), apigenin (4), N-trans-feruloyltyramine (5), N-p-coumaroyltyramine (6), daidzein (7), caffeic aicd (8), protocatechuic acid (9), daidzin (10), and N-trans-feruloyl-3-methyldopamine (11).
For the first time, compound 11 was separated from Solanaceae plant, and compounds 5 and 10 were isolated from Solanum, and compounds 1, 3, 4, 7 and 9 were obtained from this plant for the first time.
研究白英95%乙醇提取物中的化学成分。
采用硅胶柱色谱法分离化合物，经葡聚糖凝胶LH - 20柱色谱和制备薄层色谱法纯化。根据理化性质和光谱数据确定结构。
分离鉴定出11种化合物，分别为：刺芒柄花素（1）、香草酸（2）、染料木素（3）、芹菜素（4）、N - 反式阿魏酰酪胺（5）、N - 对香豆酰酪胺（6）、大豆苷元（7）、咖啡酸（8）、原儿茶酸（9）、大豆苷（10）和N - 反式阿魏酰 - 3 - 甲基多巴胺（11）。
化合物11首次从茄科植物中分离得到，化合物5和10首次从白英中分离得到，化合物1、3、4、7和9首次从该植物中获得。
