To study the aqueous constituents of Houttuynia cordata.
Various columns including Diaion HP-20, Sephadex LH-20, ODS and silica gel were employed for the isolation and purification of compounds from H. cordata. The structures of the compounds were identified by physiochemical properties and spectral analysis.
Five compounds were isolated, and their structures were identified as chlorogenic methyl ester (1), (E)-4-Hydroxy-4-[3'-(beta-D-glucopyranosyloxy) butylidene]-3, 5, 5-trimethyl-2-cyclohexen-1-one (2), 2-(3, 4-dihydroxyphenyl) ethyl-beta-D-glucopyranoside (3), p-hydroxyphenethyl-beta-D-glucoside (4), 4-(beta-D-glucopyranosyloxy)-3-hydroxy-Benzoic acid (5).
All compounds were isolated from this plant for the first time.
研究鱼腥草的水相成分。
采用多种色谱柱，包括Diaion HP - 20、Sephadex LH - 20、ODS和硅胶，从鱼腥草中分离纯化化合物。通过理化性质和光谱分析鉴定化合物的结构。
分离得到5个化合物，其结构分别鉴定为绿原酸甲酯（1）、（E）-4 - 羟基 - 4 - [3' - （β - D - 吡喃葡萄糖氧基）亚丁基] - 3,5,5 - 三甲基 - 2 - 环己烯 - 1 - 酮（2）、2 - （3,4 - 二羟基苯基）乙基 - β - D - 吡喃葡萄糖苷（3）、对羟基苯乙基 - β - D - 葡萄糖苷（4）、4 - （β - D - 吡喃葡萄糖氧基） - 3 - 羟基苯甲酸（5）。
所有化合物均首次从该植物中分离得到。
