目的: 研究新疆鼠尾草叶的化学成分。方法: 采用色谱法分离化合物,用波谱和化学方法鉴定结构。结果: 从新疆鼠尾草叶中分离得到4种化合物:β 谷甾醇(Ⅰ)、齐墩果酸(Ⅱ)、熊果酸(Ⅲ)、5 羟基 4′,6,7 三甲氧基黄酮(Ⅳ)。结论: 除β 谷甾醇、齐墩果酸、5 羟基 4′,6,7 三甲氧基黄酮外,其余均为从新疆鼠尾草的地上部分中首次得到。 Objective: To study the chemical constituents of leaves of S. chinensis in Xinjiang. Methods: The compounds were separated by chromatography and the structures were identified by spectroscopic and chemical methods. Results: Four compounds were isolated from the leaves of S. chinensis in Xinjiang: β-sitosterol (I), oleanolic acid (II), ursolic acid (III), 5-hydroxy 4′,6,7 trimethoxyflavone ( IV). Conclusion: Except for β-sitosterol, oleanolic acid, 5-hydroxy 4′,6,7 trimethoxyflavone, all the others were obtained from the aboveground part of S. senegalensis for the first time.
