Chromatographic purification of ethyl acetate soluble fraction of the methanolic extract of the flowers of Aerva javanica yielded three new acylated flavone glycosides: kaempferol-3-O-β-d-[4‴-E-p-coumaroyl-α-l-rhamnosyl(1 → 6)]-galactoside (1), kaempferol-3-O-β-d-[4‴-E-p-coumaroyl-α-l-rhamnosyl(1 → 6)]-(3″-E-p-coumaroyl)galactoside (2), and kaempferol-3-O-β-d-[4‴-E-p-coumaroyl-α-l-rhamnosyl(1 → 6)
的花的甲醇提取物的乙酸乙酯可溶级分的色谱纯化Aerva鸦胆子产生三个新的酰化黄酮苷:山奈黄素-3- ö -β- d - [4''' - ë - p -coumaroyl-α-升-rhamnosyl( 1→6)] -半乳糖苷(1),山柰酚-3- ö -β- d - [4''' - ë -对-香豆酰基α-升-rhamnosyl(1→6)] - (3“ - ë - p -coumaroyl)半乳糖苷(2),山奈酚-3- ö -β- d - [4''' - ë -p -coumaroyl-α-升-rhamnosyl(1→6)] - (4“ - ë - p -coumaroyl)半乳糖苷(3),具有沿对-香豆酸(4),咖啡酸(5),没食子酸(6),二十烷基-反-对-香豆酸酯(7),阿魏酸十六烷基酯(8)和阿魏酸十六烷基酯(9)。化合物1 - 9使用1D(进行了表征1 H,13C)和2D NMR(HM
