中药磨盘草的化学成分

目的研究中药磨盘草的化学成分。方法运用硅胶柱色谱及Sephadex LH-20柱色谱等方法分离磨盘草的化学成分,通过理化常数和1D-NMR等波谱数据鉴定化合物的结构。结果从磨盘草中分离了7个化合物,鉴定了6个化合物,分别鉴定为:β-谷甾醇(β-sitosterol,1)、齐墩果酸(oleanicacid,2)、24R-5α豆甾烷-3,6-二酮((24R)-5α-stigmastane-3,6-dione,3)、胡萝卜苷(daucosterol,4)、2,6-二甲氧基对苯醌(2,6-dimethoxy-1,4-benzoquinone,5)、香草酸(vanillic acid,6),还有一个脂肪酸类成分。结论化合物2-5均为首次从磨盘草中分得。

Investigation the chemical constituents of Abutilon indicum (L.) Sweet

Objective To investigate the chemical constituents of Abutilon indicum (L.) Sweet. Methods The compounds were separated by the combined use of column chromatography with silica gel and Sephadex LH-20. The structures of the compounds obtained were elucidated by physicochemical constants and spectroscopic methods. Results 7 compounds were isolated, and 6 of them were identified as β-sitosterol(1), oleanic acid（2）,(24R)-5α-stigmastane-3,6-dione(3), daucosterol(4), 2,6-dimethoxy-1,4-benzoquinone(5), vanillic acid (6). Conclusion Compounds 2-5 were obtained from Abutilon indicum (L.) Sweet for the first time.
