摘要
通过对金毛狗脊[Cibotium barometz(L.) J.Sm.]根茎乙醇提取物的乙酸乙酯萃取部分进行分离纯化,得到8个化合物。经物理方法和谱学分析,分别鉴定为(24R)-豆甾-4-烯-3-酮(1),24-亚甲基环木菠萝烷醇(2),β-谷甾醇(3),(3R)-去-O-甲基毛狄泼老素(4),原儿茶醛(5),金粉蕨亭(6),交链孢霉酚(7)和胡萝卜苷(8)。化合物1、2、4和7为首次从该属植物中分离得到。
Eight compounds were isolated from EtOAc-soluble fraction of 70% ethanolic extract from the rhizome of Cibotiurn barometz ( L. ) J. Sm.. On the basis of spectroscopic analysis, they were identified as (24R) -stigmst-4-ene-3-one ( 1 ) ,24-methylenecycloartanol ( 2 ),β-sitosterol ( 3 ) , (3R) -des-O-methyl laslodiplodin ( 4 ), protocatechuic aldehyde (S) ,onitin (6) ,alternariol (7) ,and daucosterol (8). Compounds 1,2,4,and 7 were isolated from the genus Cibotiurn Kaulf. for the first time.
