摘要
目的 研究鬼针草Bidens bipinnata的化学成分。方法 应用硅胶、Sephadex LH-20、制备液相等多种色谱技术进行分离纯化,并通过多种波谱分析方法鉴定化合物。结果 从鬼针草95%乙醇提取物中分离得到18个化合物,分别鉴定为槲皮素-5-O-β-D吡喃葡萄糖苷(1)、奥卡宁-4′-O-β-D-(2″, 4″, 6″-三乙酰基)-吡喃葡萄糖苷(2)、奥卡宁-4′-O-β-D-(3″,4″-二乙酰基-6″-反式-对-香豆酰基)-吡喃葡萄糖苷(3)、木犀草素-7-O-β-D-吡喃葡萄糖苷(4)、山柰酚-7-O-β-D-吡喃葡萄糖苷(5)、山柰酚-3-O-β-D-芸香糖苷(6)、槲皮素-3-O-β-D-吡喃葡萄糖苷(7)、槲皮素-7-O-β-D-吡喃葡萄糖苷(8)、金丝桃苷(9)、芦丁(10)、柚皮素(11)、芹菜素(12)、槲皮素(13)、5, 7-二羟基色原酮-7-O-β-D-葡萄糖苷(14)、咖啡酸(15)、没食子酸(16)、β-谷甾醇(17)、胡萝卜苷(18)。结论 化合物1和11为首次从鬼针草属植物中分离得到,化合物3~7、14、15、18为首次从鬼针草中分离得到。
Objective To study the chemical constituents from the herbs of Bidens bipinnata. Methods The compounds were isolated and purified by various column chromatographies. Their structures were elucidated by means of physicochemical properties and spectral analyses (MS, 1H-NMR, and 13C-NMR). Results Eighteen compounds were isolated from 95% ethanol extract of B. bipinnata and identified as quercetin-5-O-β-D-glucopyranoside (1), okanin-4′-O-β-D-(2″, 4″, 6″-triacetyl)-glucopyranoside (2), okanin-4′-O-β-D-(3″, 4″-diacetyl-6″-trans-p-coumaroyl)-glucopyranoside (3), luteolin-7-O-β-D-glucopyranoside (4), kaempferol- 7-O-β-D-glucopyranoside (5), kaempferol-3-O-β-D-rutinoside (6), quercetin-3-O-β-D-glucopyranoside (7), quercetin-7-O-β-D- glucopyranoside (8), hyperoside (9), rutin (10), naringenin (11), apigenin (12), quercetin (13), 5, 7-dihydroxy chromone-7-O-β-D-glucoside (14), caffeic acid (15), gallic acid (16), β-sitosterol (17), and sitosterol-3-O-glucopyranoside (18). Conclusion Compounds 1 and 11 are obtained from the plants in Bidens L. for the first time, and compounds 3—7, 14, 15, and 18 are firstly obtained from this plant.
