摘要: 从水朝阳旋覆花( Inula helianthus-aquatica) 的95% 乙醇提取物中分离得到4 个麝香草酚类化合物, 其中化合物1 为新化合物。它们的化学结构通过波谱方法鉴定为: 8-hydroxy-9 , 10-dioxyisopropylidene-thymol (1) , 10-hydroxy-8 , 9-dioxyisopropylidene- thymol (2) , 8-hydroxy-9 , 10-diisobutyryloxy- thymol ( 3) 和8 , 10-dihydroxy-
9-isobutyryloxy- thymol (4)。肿瘤细胞毒试验结果表明它们在6 种肿瘤细胞株上(K562 , HT-29 , SGC-7901, DU145 , MDA-MB-231 , U251 ) 显示一定的细胞毒活性, 其中化合物2 活性最强, 它的IC50 值为4 . 20~33 . 12 μmol/L。具有细胞毒活性的麝香草酚类化合物是首次在该种植物中发现。

Abstract: A new thymol derivative, 8-hydroxy-9 , 10-dioxyisopropylidene- thymol (1 ) , together with three known thymol derivatives 10-hydroxy-8, 9-dioxyisopropylidene-thymol (2 ) , 8-hydroxy-9 , 10-diisobutyryloxy- thymol ( 3 ) and 8 , 10-dihydroxy-9-isobutyryloxy- thymol (4) , was isolated from 95% EtOH extract of the flowers of Inula helianthus-aquatica. Their structures were elucidated on the basis of detailed spectroscopic analysis . These compounds showed cytotoxicities on six cancer cell lines (K562 , HT-29 , SGC-7901, DU145, MDA-MB-231 , U251) , and compound 2 is the strongest one with IC50s of 4 .20 - 33. 12μmol􊄯L . This is the first time that the cytotoxic thymol derivatives were isolated from this titled plant .
