To investigate the chemical constituents from roots of Boehmeria nivea.
The constituents were isolated by repeated column chromatography and preparative liquid chromatography; and their structures were elucidated by chemical properties and spectroscopic analyses.
Seven compounds were isolated and their structures were identified as tormentic acid (1), hederagenin (2), maslinic acid (3), 2alpha-hydroxyursolic acid (4), trans-p-hydroxycinamic acid (5), 2,4,4'-trihydroxychalcone (6), rutin (7).
Compounds 1-6 were obtained from this genus for the first time.
研究苎麻根的化学成分。
通过反复柱色谱和制备液相色谱分离化合物；并通过化学性质和光谱分析阐明其结构。
分离得到7个化合物，其结构分别鉴定为 tormentic 酸（1）、常春藤皂苷元（2）、山楂酸（3）、2α - 羟基熊果酸（4）、反式对羟基肉桂酸（5）、2,4,4'- 三羟基查耳酮（6）、芦丁（7）。
化合物1 - 6首次从该属植物中获得。
