+ | Main component of the hydrodistilled (with cohobation, continuous re-injection of the hydrosol into the still) essential oil of freshly mazerated stems and leaves of G.procumbens (collected in the Canadian boreal forest) was methyl salicylate (98.7%). A minor component was ethyl salicylate (0.5%). \\ | ||
