摘要
目的:研究白益母草乙酸乙酯部位的化学成分。方法:采用硅胶柱色谱法对白益母草乙酸乙酯部位进行分离,利用波谱数据解析化合物结构。结果:从白益母草乙酸乙酯部位中分离鉴定了9个化合物,分别为:7-甲氧基香豆素(1)、异鼠李素(2)、咖啡酸(3)、5-羟基-7,3',4'-三甲氧基黄酮(4)、5-羟基-7,4'-二甲氧基黄酮(5)、山柰酚(6)、异鼠李素-3-O-β-D-葡萄糖苷(7)、山柰酚-3-O-β-D-葡萄糖苷(8)、异鼠李素-3-O-β-D-葡萄糖基-(1→6)-O-α-L-鼠李糖苷(9)。结论:其中,化合物1~4、6、7和9为首次从该植物中分离得到。
Objective : To study the chemical constituents of the ethyl acetate extract from Panzeria alaschanica. Methods : The chemical constituents of ethyl acetate extract from Panzeria alaschanica were isolated and purified by silica gel. Their structures were i- dentified by means of spectra. Results : Nine compounds were obtained and identified as 7-Methoxy coumarin ( 1 ), Isorhamnetin (2), Caf- feic acid ( 3 ), 5-Hydroxy-7,3', 4'-trimethoxyflavone ( 4 ), 5- Hydroxy-7,4'-dimethoxyflavone ( 5 ), Kaempferol ( 6 ), Isorhamnetin-3-O-α-D- glucoside ( 7 ), Kaempferol-3-O-β-D-glucoside ( 8 ), and Isorhamnetin-7-O-β-D-glucuronyl- ( 1 --→6 ) -O-α-L-rhamnoside ( 9 ). Conclusion : Compounds 1 -4,6,7 and 9 are isolated from this plant for the first time.
