Abstract： 目的研究黑桑Morus nigra茎的化学成分.方法利用硅胶或ODS柱色谱进行分离纯化,通过波谱技术鉴定化合物的结构.结果分离得到8个化合物,分别鉴定为羟基白藜芦醇(hydroxyresveratrol,Ⅰ)、二氢桑色素(dihydromorin,Ⅱ)、桑色素(morin,Ⅲ)、sanggenol F(Ⅳ)、sanggenol H(Ⅴ)、2,4,2',4'-四羟基-3-(3-甲基-2-丁烯基)-查耳酮(2,4,2',4'-tetrahydroxy-3-(3-methyl-2-butenyl)-chalcone,Ⅵ)、乌索酸(ursolic acid,Ⅶ)和β-谷甾醇(β-sitosterol,Ⅶ).结论化合物Ⅰ～Ⅶ均为首次从该植物中分离得到.利用HMQC和HMBC谱正确归属了化合物Ⅵ的部分核磁共振谱信号.
