光叶桑中的Diels-Alder型加合物

Diels-Alder type adducts of Morus macroura Miq.

目的：对光叶桑（Morus macroura）中的Diels-Alder型加合物进行研究。方法：硅胶、Sephadex LH-20、Rp C-18、Rp C-8色谱柱分离纯化，理化性质、光谱数据鉴定结构。结果：鉴定8个Diels-Alder型加合物，分别为albafuranC（1）、kuwanon P（2）、kuwanon Y（3）、kuwanon X（4）、mulberrofuran j（5）、mulberrofuran C（6）、kuwanon J（7）和sorocein A（8）。结论：化合物1～8为首次从该植物中分离得到，其中化合物8为首次从桑属植物中发现。

Aim： To conduct detailed investigation of the Diels-Alder type adducts of Morus macroura Miq.. Methods：The compounds were isolated and purified by Sephadex LH-20, Rp C-18, Rp C-8 and silica gel column chromatography. Their chemical structures were elucidated on the basis of physico-chemical properties and spectral data. Results：Eight compounds were isolated and identified as： albafuran C （1）, kuwanon P （2）, kuwanon Y （3）, kuwanon X （4）, mulberrofuran J （5）, mulberrofuran C （6）, kuwanon J （7） and sorocein A （8）. Conclusion： Compounds 1 ～8 were obtained from this plant and compound 8 was isolated from Morus both for the first time.
