摘　　要：为寻找结构多样的具有细胞毒活性的真菌代谢物,采用多种色谱分离技术对粉红单端孢霉(Trichothecium roseum)固体发酵代谢产物成分进行分离纯化,得到5个化合物,利用HR-ESI-MS、1H NMR和13 C NMR等谱学技术对其结构进行鉴定,分别确定为melanocane F(1)、rosenonolactone(2)、desoxyrosenonolactone(3)、rosonolactone(4)与2α-hydroxyisocupressic acid(5),均为二萜类化合物,其中化合物1为新化合物。对所有化合物进行乳腺癌MCF-7细胞毒活性研究,结果表明化合物1和5抑制MCF-7生长活性较好。In order to search for fungal metabolites with various structures and cytotoxic activities,the metabolites of Trichothecium roseum solid fermentation were isolated and purified by various chromatographic techniques.Five diterpenoids were obtained from the fermentation broth of Trichothecium roseum,their structures were identified as one new diterpene compound,melanocane F(1)and four known compounds,rosenonolactone(2),desoxyrosenonolactone(3),rosonolactone(4)and 2α-hydroxyisocupressic acid(5)by the analysis of spectroscopic data including HR-ESI-MS,1H NMR and 13 C NMR.All compounds were evaluated for their cytotoxic activity on MCF-7 cells.As a result,compounds 1 and 5 showed the most significant inhibitory activity on MCF-7 cells.
