Abstract Four tovarol, two epoxytovarol (= shiromodiol) and one diepoxytovarol esters were the new germacrane esters isolated from the roots of Thapsia villosa var. minor . The structures of these substances were assigned on the basis of spectral data and chemical correlations with shiromodiol. The acid catalysed rearrangement of tavarol yielded 1(10),4-bulgaradiene-8-ol.
