摘要:
目的 研究云南独蒜兰化学成分,发现其活性成分。 方法 云南独蒜兰乙酸乙酯提取、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 从该药用植物乙酸乙酯萃取部分分离并鉴定了5个化合物，分别为：gigantol（1），batatasin III（2），2-methoxy-4,7-dihydroxy-9,10-dihydrophenanthrene（3），2,7-dihydroxy-4-methoxy-9,10-dihydrophenanthrene（4），2,7-dihydroxy-4-methoxyphenanthrene（5）。 结论 化合物5为首次从本植物中分离得到。 Abstract:Objective Study the chemical compounds from the plants of P. yunnanensis and find its bioactive constituents. Methods The compounds were extracted by ethyl acetate and isolated by column chromatography on silica gel and Sephadex LH-20. 1H NMR, 13CNMR and EI-MS were used to elucidate their structure. Results Five compounds including gigantol （1）, batatasin III （2）, 2-methoxy-4,7-dihydroxy-9,10-dihydrophenanthrene （3）, 2,7-dihydroxy-4-methoxy-9,10-dihydro-phenanthrene （4）, 2,7-dihydroxy-4-methoxyphenanthrene （5） were obtained. Conclusion Compound 5 was isolated from the plant for the first time. -
