    In this study, investigation on the essential oils and ethanol extracts of naturally grown and cultivatedSatureja macrantha samples were reported. The essential oil, flavour and terpenoid-steroid-flavonoid contents of S.macrantha samples were determined by GC-MS and their phenolic contents by LC-MS/MS. Besides, the biologicalactivities of the samples were investigated for their antioxidant, anti-Alzheimer, antimicrobial, cytotoxic,antityrosinase, antiurease, antielastase and anticollagenase properties. The phenolic content and antioxidant capacityof the cultivated sample were higher than those of the naturally grown sample. According to the GC-MS results,terpinene-4-ol (30.9%) and p-cymene (56.7%) were determined as the major components in the essential oils of thenaturally grown and cultivated S. macrantha, respectively. The flavour analysis results showed that cis-sabinenehydrate (20.7%) and carvacrol (42.2%) were found to be the major components in the naturally grown and cultivatedsamples, respectively. While the naturally grown sample was rich in abietane diterpenoids (ferruginol (17.5 mganalyte/g extract) and sugiol (4.2 mg analyte/g extract)), these components were not detected in the cultivatedsample. The rosmarinic acid content (0.20 and 24.87 mg analyte/g extract, respectively) of the cultivated samplewas found to be significantly higher than that of the natural sample. The biological activities of the samples weredetermined to be changed in parallel with their chemical contents that are due to factors such as climatic conditions,and soil structure.
