    Studies on Chemical Constituents from Chrysanthemum Indicum L.

    • 摘要: 目的 研究野菊花的化学成分。方法 用80%乙醇提取野菊花化学成分,通过硅胶反复柱层析、纯化,用各种波谱数据分析鉴定化合物的结构。结果 从野菊花头状花序中的乙酸乙酯提取物、氯仿提取物及正丁醇提取物中分离得到11个化合物,分别鉴定为香叶木素(Ⅰ),木犀草素(Ⅱ),木犀草素-7-O-β-D-葡萄糖苷(Ⅲ),芹菜素(Ⅳ),β-谷甾醇(Ⅴ),山奈酚(Ⅵ),大黄酚(Ⅶ),蒙花苷(Ⅷ),金合欢素(Ⅸ),金合欢素-7-O-(6″-O-乙酰基)-β-D-葡萄糖苷(Ⅹ)和金合欢素-7-O-β-D-芦丁糖苷(Ⅺ)。结论 其中化合物Ⅹ~Ⅺ为首次从野菊花中分离得到。

       

      Abstract: OBJECTIVE To study the chemical constituents in Chrysanthemum indicum L. METHODS Extract chemical continents from Chrysanthemum indicum L. by using 80% alcohol and silica gel column chromatography methods. The structure of the isolated compounds were identified by physicochemical identification and spectral analysis methods, such as UV, FTIR, EI-MS, ESI-MS, 1H-NMR, 13C-NMR, and so on. RESULTS Eleven compounds were isolated from the ethyl acetate extracts, chloroform extracts and the n-butanol extracts of Chrysanthemum indicum L. They were chrysoeriol(Ⅰ) , luteolin(Ⅱ) , luteolin-7-O-β-D-glucopyranoside (Ⅲ), apigenin(Ⅳ), β-sitosterol(Ⅴ), kaempferol(Ⅵ), chrysophanol(Ⅶ), linarin(Ⅷ), acacetin(Ⅸ), acacetin 7-O-(6″-O-acetyl)-β-D-glucopyranoside(Ⅹ) and acacetin-7-O-β-D-rutinoside(Ⅺ), respectively. CONCLUSION Among them, compounds Ⅹ and Ⅺ were isolated from Chrysanthemum indicum L. for the first time.
