OBJECTIVE
To study the chemical constituents of Penthorum chinense.
METHOD
Silica gel and macroporous resin were used as adsorbent for isolation and purification. The chemical structures were elucidated by spectral analysis and chemical methods.
RESULT
Three compounds were isolated from the water-extract of P. chinense. The structures were identified as 5-hydroxy-flavanone-7-O-beta-D-glucoside (I), 2,4,6-trihydroxybenzoic acid (II) and quercetin(III), respectively.
CONCLUSION
Compounds I and II were isolated from this plant for the first time.
目的
研究扯根菜的化学成分。
方法
采用硅胶和大孔树脂作为吸附剂进行分离纯化。通过光谱分析和化学方法阐明化学结构。
结果
从扯根菜水提取物中分离出3种化合物。其结构分别鉴定为5-羟基黄酮-7-O-β-D-葡萄糖苷（I）、2,4,6-三羟基苯甲酸（II）和槲皮素（III）。
结论
化合物I和II首次从该植物中分离得到。
