摘要: 利用超临界提取技术对中药鹅不食草中的小极性成分进行富集,并经过硅胶柱色谱、Sephadex LH-20柱色谱和制备型高效液相色谱等分离技术从鹅不食草中分离得到11个化合物。根据它们的波谱数据和理化性质分别鉴定为:短叶老鹳草素(1)、4,5-β-dihydroxy-2-β-(isobutyryloxy)-10-β-H-guai-11(13)-en-12,8-β-olide(2)、arnicolide C(3)、microhelenin C(4)、arnicolide B(5)、乌苏酸(6)、8-羟基-9,10-双异丁酰氧基百里酚(7)、3-甲氧基槲皮素(8)、3,3′-二甲氧基槲皮素(9)、胡萝卜苷(10)、豆甾醇(11)。其中化合物4和6首次从该植物中分离得到。

Abstract: Eleven compounds were isolated from Centipeda minima and purified by repeated silica gel,Sephadex LH-20 column chromatography,and preparative HPLC.The structures were elucidated on the basis of their spectral characteristics and identified as brevifolin (1),4,5-β-dihydroxy-2-β-(isobutyryloxy)-10-β-H-guai-11(13)-en-12,8-β-olide (2),arnicolide C (3),microhelenin C (4),arnicolide B (5),ursolic acid (6),8-hydroxy-9,10-diisobutyryloxythymol (7),quercetin-3-methyl ether (8),quercetin3,3′-dimethyl ether (9),daucosterol (10),stigmasterol (11).Compounds 4 and 6 were isolated from this plant for the first time.
