Four new eudesmane-type sesquiterpenoids have been isolated from the ether extract of Lepidozia vitrea. Their structures were elucidated by spectral means and were shown to be eudesm-3-ene-6 alpha-acetoxy-7 alpha-ol, eudesm-3-ene-7 alpha-ol, eudesm-4(15)ene-6 beta,7 alpha-diol and eudesm-4(15)-ene-7 alpha-ol. These compounds were isolated together with the previously known sesquiterpenes (-)-isobicyclogermacrenal,(-)-lepidozenal, maalian-5-ol and (+)eudesm-3-ene-6 beta,7 alpha-diol.
