摘要 目的:研究一点红地上部分乙醇提取物的化学成分。方法:采用多种色谱技术进行分离纯化,通过理化性质和波谱技术分析鉴定化合物的结构。结果:从一点红90%乙醇提取物的乙酸乙酯部分分离得到15个化合物,主要为黄酮和有机酸类,分别为鼠李素(1),异鼠李素(2),槲皮素(3),木犀草素(4),小麦黄素-7-O-β-D-吡喃葡萄糖苷(5),8-(2″-吡咯烷酮基)-槲皮素(6),5,2',6'-三羟基-7,8-二甲氧基-黄酮-2'-O-β-D-吡喃葡萄糖苷(7),丁二酸(8),反式丁烯二酸(9),对羟基苯甲酸(10),4-羟基-间苯二甲酸(11),咖啡酸(12),七叶内酯(13),异去甲蟛蜞菊内酯(14)及尿嘧啶(15)。结论:除化合物3外,其余均为首次从该属植物中分离得到。 Objective: To study the chemical constituents contained in ethanol extracts from aerial parts of Emilia sonchifolia. Method: The compounds were separated and purified with various chromatographic techniques, and their structures were identified on the basis of physicoehemical properties and spectral data. Result: Fifteen compounds were separated from ethyl acetate fraction of 90% ethanolic extract and identified as rhamnetin ( 1 ) , isorhamnetin ( 2 ) , quercetin ( 3 ) , luteolin ( 4 ) , tricin-7-O-/3-D-glucopyranoside ( 5 ) , 8-(2"-pyrrolidinonc-5"-yl)-quercetin(6) ,5,-2',6'-trihydroxy-7,8-dimethoxyflavone-2'-O-fl-D-glucopyranoside(7),succinic acid(8) , fumaric acid ( 9 ) , p-hydroxybenzoic acid ( 10 ) , 4-hydroxy isophthalic acid ( 11 ) , 3,4-dihydroxycinnamic acid ( 12 ) , esculetiu ( 13 ) , isowedelolaetone ( 14 ) and uracil ( 15 ) , respectively. Conclusion: All compounds except compound 3 were separated from this genus for the first time.
