Opis (eng)

ABSTRACT Medicinal and aromatic plants have been traditionally used as an important source of therapeutic constituents. The genus Satureja contains about 200 aromatic and medicinal plant species, which grow in the Middle East and Mediterranean European regions, West Asia, North Africa, and South America. Satureja montana L. commonly contains around 5% of the essenytial oil that shows antioxidant, antimicrobial, diuretic, antidiarrheal, anticholinesterase, carminative, digestive, and cytotoxic activities. The essential oil provides the basis for a wide range of biological and industrial applications due to a high content of biologically active constituents. In the present study, the essential oils from two chemotypes of S. montana, ct. carvacrol (SMc), and ct. thymol (SMt) were isolated using a conventional hydro-distillation method (100 g of plant/1500 mL of dH2O, 3 h). The areal parts of S. montana flowering plants were harvested from the experimental field of the Institute for Medicinal Plants Research "Dr Josif Pančić" in Pančevo, South Banat, Serbia. The chemical composition of the obtained essential oils was determined using GC-MS analysis, while antioxidant capacity was examined using two antioxidant assays (ABTS and DPPH methods). The GC-MS analysis showed that in the SMc essential oil 43 compounds were identified and quantified, while in the SMt essential oil there were 45 compounds. The most dominant compound in SMc essential oil was carvacrol (39.49%), followed by thymol (30.43%), γ-terpinene (9.68%), p-cimene (5.71%), transcaryophyllene (2.42%), β-bisabolene (1.96%), α-terpinene (1.41%) borneol (1.35%), myrcene (1.08%), and 1-octen-3-ol (1.04%), while the remaining constituents were presented in the amounts below 1% of the total content. The most abundant component in SMt essential oil was thymol (70.69%), followed by carvacrol (7.06%), p-cimene (5.71%), γ-terpinene (3.85%), βbisabolene (2.44%), and borneol (1.10%), whereas other oil constituents ranged from 0.03 to 0.89%. For SMc and SMt essential oils, the total content of monoterpene hydrocarbons was 19.61 and 12.99%, of oxygenated monoterpenes, 74.83 and 82.13%, of sesquiterpene hydrocarbons, 4.91 and 3.95%, and of oxygenated sesquiterpenes, 0.36 and 0.51%, respectively. According to the ABTS experiment, SMc and SMt had antioxidant capacities of 96.5 and 98.2%, respectively, whereas their respective capacities to neutralize DPPH radicals were 92.0 and 89.8%. The research presented here provides evidence on the chemical composition as well as the ABTS and DPPH radical scavenging potential of two different chemotypes of S. montana essential oils, as well as a foundation for their potential encapsulation and further application.
