Four thymol derivatives, 2,5-dimethoxythymol (1), 2-methoxythymol isobutyrate (2), 10-isobutyloxy-8,9-epoxythymolisobutyrate (3) and 10-(2-methylbutyloxy)-8,9-eposythymolisobutyrate (4) were isolated from the aerial parts of Carpesium divaricatum. the structures were elucidated by high field 1D and 2D NMR techniques.
