Taxus L. is accepted in the literature as natural resources of biologically active compounds and volatile oils, with applications in medicine, pharmaceuticals, food, cosmetics, and with ecological impact on the natural living environment. In this context, the present work aims to analyze by GS/MS techniques the chemical composition of volatile oil obtained by hydrodistillation of leaves harvested from spontaneous and cultivated female individuals of Taxus (dried and fresh plant material) and to spectrophotometrically evaluate the hydrosols resulting from their hydrodistillation. The compounds with the highest concentrations in the volatile oil obtained from the spontaneous taxon Taxus baccata L. were hexahydrofarnesyl acetone (33.03% fresh leaves; 20.09% dried leaves); ar-abietatriene (14.98% dried leaves; 3.03% fresh leaves); phthalic acid, hex-3-yl isobutyl ester (10.51% dried leaves); salicylic acid, benzyl ester (8.11% dried leaves). In the cultivated taxon Taxus baccata the compounds identified with the highest concentrations were 1-octen-3-ol (25.61% fresh leaves); phytol (12.50% dry leaves); geranyl acetone (11.90% dry leaves); manoyl oxide (11.85% dry leaves; 10.86% fresh leaves); 1,9-decadence (7.92% fresh leaves). The compounds with the highest concentrations in the oil extracted from the leaves of Taxus baccata ‘Robusta’ were hexahydrofarnesyl acetone (17.81% fresh leaves); pentacosane (11.28% dry leaves); heptacosane (11.27% fresh leaves); tetracosane (11.13% dry leaves); tricosane (8.45% fresh leaves). The chemical composition of volatile oils from yew is influenced by many exogenous factors such as soil, light, and endogenous factors such as age, DNA.
