云南傣药竹叶兰化学成分的研究

目的 研究云南傣药竹叶兰化学成分,发现其活性成分.方法 竹叶兰全草经溶剂提取、硅胶柱层析和Sephadex LH-20柱层析进行分离纯化,波谱分析(核磁共振氢谱、碳谱、和质谱)确定结构.结果 从该药用植物分离并鉴定了8个化合物,分别为:(1)7-hydroxy-2,4-dimethoxy-9,10-dihydrophenanthrene;(2)coelonin;(3)4,7-dihydro-xy-2-methoxy-9,10-dihydrophenanthrene;(4)ephemeranthoquinone;(5)densiflorol B;(6)4-(3-hydroxyphenyl)-2-butanone;(7)stigmasterol;(8)β-sitosterol.结论 化合物6为首次从竹叶兰中得到.

Study on the Chemical Constituents of Arundina graminifolia

Objective To study the chemical constituents from the flowers of Arundina graminifolia and to find its bioactive compounds. Methods The compounds were extracted by 95% alcohol and isolated by column chromatography on silica gel and Sephadex LH-20. The structures were identified by spectroscopic analysis(1H NMR,13 CNMR and EIMS). Results Eight compounds were obtained and identified as(1) 7-hydroxy-2,4-dimethoxy-9,10-dihydrophenanthrene;(2)coelonin;(3)4,7-dihydroxy-2-methoxy-9,10-dihydro-phenanthrene;(4)ephemeranthoquinone;(5)densiflorol B;(6)4-(3-hydroxyphenyl)-2-butanone;(7)stigmasterol,(8)β-sitosterol.Conclusion Among them, compound 6 is discovered for the first time from the plant.
