This study aims to see if different patterns of chemical composition from wild and cultivated Salvia Officinalis L. chemo types are obtained. Ten representative samples were taken in different locations. They were collected from a large number of plants, representing the population of the sampling stations, during the flowering stage, June. Essential oils were analysed, using GC-FID and GC MS/MS. Both wild and cultivated ecotypes preserve Salvia Officinalis L. species characteristics, relating to chemical composition patterns, but show differences in individual chemical compounds content. Sage originating from imported seed cultivated in north resulted richer in Camphor (32.02%). Sage originating from wild Albanian seeds, cultivated in north-west preserved the north ecotype and, resulted richer in α-thujone (41.34%). a-thujone in wild sage of north and north–west, resulted, from 32.88% to 46.64%, and Camphor, 14.39% to 19.53% (Bardhoc/M4 & Hani I Hotit/M1). Environmental factors seem to have no influence in this case. Cultivated sage plants, originating from plant cutting of wild Albanian ecotype sage, preserve the typical pattern of chemical content and composition for the respective locations, they were cultivated. In north (Koplik/M2), both cultivated and wild resulted rich in a-thujone, 34.62%, and 37.32%. In south (Gjirokaster/M8 & Dragot/M9), cultivated and wild resulted rich in Camphor, varying from 24.31%-29.34% and 39.47%-41.38% respectively, inheriting the same chemo type of wild indigenous populations. Cultivated sage plants, originating from wild Albanian ecotypes, preserve the essential oil composition pattern, even in different geographic positions. Seeds’ genetic background seems to be a factor impacting essential oil composition patterns. This factor could be used for selection and cultivation purposes.
