【摘要】 目的:研究鬼箭羽 Euonymus alatus(Thunb.)Sieb.的化学成分。方法:利用柱色谱分离,经理化常数测定,结合1H-NMR、 13C-NMR、EI-MS 鉴定结构。结果:从鬼箭羽的95%乙醇提取物的石油醚、氯仿、乙酸乙酯萃取层中共分离得到14个化合物,分别鉴定为(+)-松萝酸(1)、香草醛(2)、2-羟基4-甲氧基-3,6-二甲基苯甲酸(3)、2,4-二羟基-3,6-二甲基苯甲酸甲酯(4)、 2,4-二羟基-6-甲基苯甲酸甲酯(5)、4-甲基-7-甲氧基-异苯并呋喃酮(6)、羽扇豆醇(7)、3β-羟基-30-降羽扇豆烷-20-酮(8)、表木栓醇(9)、(2R,3R)-3,5,7,4′-四羟基二氢黄酮(10)、山柰酚(11)、5,7,4′-三羟基二氢黄酮(12)、豆甾-4-烯-3-酮(13)、 6β-羟基-豆甾-4-烯-3-酮(14)。结论:化合物6为新天然产物,化合物1~5,8和12为首次从该属植物中分离得到。
【Abstract】 Objective:To study the chemical constituents in Euonymus alatus (Thunb.) Sieb.Methods:Compounds were isolated and purified repeatedly by silica gel,Sephadex LH-20 column chromatography,and their chemical structures were elucidated by their physicochemical properties and spectral data,such as 1H-NMR,13C-NMR and EI-MS.Besults:Fourteen compounds were obtained and identified as (+)-usnic acid (1),vanillin (2),2-hydroxy-4-methoxy-3,6-dimethyl benzoic acid (3),methyl 2,4-dihydroxy-3, 6-dimethyl benzoate (4),methyl 2,4-dihydroxy-6-methyl benzoate (5),7-methoxy-4-methylphthalide (6),lupeol (7), 3β-hydroxy-30-norlupan-20-one(8),epifriedelinol (9),(2R,3R)-3,5,7,4’-tetrahydroxy flavanone (10),kaempferol (11),5,7,4’ -trihydroxy flavanone(12),stigmast-4-en-3-one(13),6β-hydroxy-stigmast-4-en-3-one (14).Conclusion:Compound 6 is first reported as a natural product,and compounds 1~5,8 and 12 are reported from this genus for the first time.
