Two new thymol derivatives from Eupatorium fortunei .

Two new thymol derivatives ( 1-2 ) were isolated from the aerial parts of Eupatorium fortunei . Their structures were elucidated on the basis of comprehensive spectroscopic data analysis as 8,9-dehydrothymol-3- O - β -glucoside ( 1 ), and 9-(acetyloxy)thymol-3-yl (3-methylbut-2-enoate) ( 2 ). All isolates were evaluated for cytotoxic activities with IC50 values greater than 50 μM in vitro against MCF-7, HeLa, A549, and Hep G-2 cancer cells.
