To study the constituents of ethyl acetate fraction form Hypericum hengshanense.
The constituents were isolated and purified by chromatography on silica gel and their structures were elucidated by MS and NMR spectral analysis.
Ten compounds were isolated and identified as: hyperoside (1), hypericin (2), quercetin (3), quercitrin (4), sesamin (5), betulonic acid (6), rutin (7), kaempferol (8), beta-daucosterol (9), beta-sitosterol (10).
All compounds are obtained from this plant for the first time.
研究衡山金丝桃乙酸乙酯部位的化学成分。
采用硅胶柱色谱法进行分离纯化，通过质谱（MS）和核磁共振光谱（NMR）分析确定其结构。
分离鉴定出10个化合物，分别为：金丝桃苷（1）、金丝桃素（2）、槲皮素（3）、槲皮苷（4）、芝麻素（5）、桦木酸（6）、芦丁（7）、山柰酚（8）、β-胡萝卜苷（9）、β-谷甾醇（10）。
所有化合物均为首次从该植物中获得。
