To investigate the chemical constituents in the roots of Polygonum amplexicaule var. sinense.
The compounds were isolated by column chromatography on silica gel and Sephadex LH-20. The structures were identified by means of IR, 1H-NMR, 13C-NMR and MS analyses.
Eight compounds were isolated and identified as friedelin (1), beta-sitosterol (2), simiarenone (3), angelicin (4), psoralen (5), palmitic acid (6), (-)-epicatechin (7), and quercetin (8), respectively.
All compounds were isolated from this species for the first time and compounds 1, 3-6 were obtained from this genus for the first time.
研究中华抱茎蓼根中的化学成分。
采用硅胶柱色谱和葡聚糖凝胶LH - 20柱色谱分离化合物，通过红外光谱（IR）、核磁共振氢谱（1H - NMR）、核磁共振碳谱（13C - NMR）和质谱（MS）分析鉴定结构。
分离鉴定出8种化合物，分别为蛇麻脂醇（1）、β - 谷甾醇（2）、西米杜鹃醇（3）、白芷内酯（4）、补骨脂素（5）、棕榈酸（6）、（ - ） - 表儿茶素（7）和槲皮素（8）。
所有化合物均为首次从该物种中分离得到，化合物1、3 - 6为首次从该属中获得。
