【摘要】 目的 :从金银花LonicerajaponicaThunb .中分离出活性成分环烯醚萜苷类化合物。方法 :金银花 70 %乙醇提取物依次用石油醚、乙酸乙酯和正丁醇提取 ,乙酸乙酯部位采用反复硅胶柱层析进行分离、纯化。通过波谱方法鉴定结构。结果 :分离得到一个新的裂环环烯醚萜苷 ,命名为dehydromorroniside。结论 :该化合物为忍冬属中发现的第 3个morro niside型裂环环烯醚萜苷更多还原

【Abstract】 AIM: Iridoid glucosides were expected to be isolated from the flower buds of Lonicera japonica Thunb.. METHOD:The 70% EtOH extract of L. japonica was successively partitioned with petroleum ether, ethyl acetate and n-BuOH. The ethyl acetate fraction was subjected to silica gel column to afford the compound (1). RESULT: On the basis of the spectral analysis, the structure was confirmed as dehydromorroniside. CONCLUSION: This compound was the third morroniside type secoiridoid glucoside reported in the genus Lonicera.更多还原
