摘要
目的:研究桑白皮Morus alba的化学成分。方法:应用硅胶、Sephadex LH-20和Rp-C18柱色谱进行分离纯化,根据化合物的理化常数和波谱数据鉴定其结构。结果:从桑白皮根皮中分离得到10个化合物,分别鉴定为桑根醇P(1),环桑辛素(2),桑辛素(3),桑呋喃G(4),桑根醇A(5),桑根醇L(6),桑根醇N(7),环桑素(8),cyclocommunol(9)和熊果酸(10)。结论:化合物1为新化合物,化合物5,6,7和9为首次从该植物中分离得到。
Sanggenol P(1),a new isoprenylated flavonoid,together with nine known ones,cyclomorusin(2),morusin(3),mulberrofuran G(4),sanggenol A(5),sanggenol L(6),sanggenol N(7),cyclomulberrin(8),cyclocommunol(9) and ursolic acid(10) was isolated from Morus alba L.Sanggenol P(1) was characterized based on extensive IR,UV,1D and 2D NMR spectroscopic analysis.Compounds 5,6,7 and 9 were obtained from this plant for the first time.
