Abstract Lemon verbena (Lippia citriodora H.B.K., Verbenaceae family) is indigenous to South America and cultivated as an aromatic plant in various parts of world. Lemon thyme (Thymus citriodorus L.), Lamiaceae family, is a perennial medicinal plant native to southern Europe and is cultivated in the Mediterranean region. These species are cultivated mainly for the lemon-like aroma emitted from their leaves due to the presence of dimethyl-2,6- octadienal, also known as lemonal or citral, which is used in food and perfumery for its citrus effect. The aim of this study was to determine the mineral content and essential oil components of L. citriodora and T. citriodorus plants grown under semi-arid climatic conditions in Turkey. The aerial parts of lemon thyme and lemon verbena plants were extracted using hydrodistillation. The essential oil composition was analyzed by gas chromatography-mass spectrometry (GC-MS) and the microelement contents of the herbs were examined via inductively coupled plasmaoptical emission spectrometry (ICP-OES). The microelement contents were 0.249, 1.630, 16.41, 0.106, and 13.1-36.2 mg kg-1 for cadmium (Cd), copper (Cu), iron (Fe), and manganese (Mn), respectively, in lemon thyme, and 0.275, 4.584, 248.1, 15.71, and 1.803 mg kg-1 for Cd, Cu, Fe, Mn, and zinc (Zn), respectively, in lemon verbena. Fifty compounds were identified in lemon verbena essential oil, including limonene (30.33%), trans-citral (17%), cis-citral (12.77%), caryophyllene oxide (5.71%), and geraniol acetate (4.02%) that together constituted 99.86% of the oil composition. We also identified 22 compounds constituting approximately 85.11% of lemon thyme essential oil, including transgeraniol (30.07%), trans-citral (15.06%), cis-citral (11.71%), cis-geraniol (7.65%), and 3-octanol (6.18%).

This investigation was carried out to study the Bay leaves (Laurus nobilis) and extracted three types of Aqueous, Ethanolic alcohol, Essential oil extracts of leaf plant powder study. The performance of extracts as anti-oxidant agent were evaluated by estimate the value of Thiobarbituric acid (TBA) of sunflower oil to these extracts in concentrate% 0.04 and %0.02 compared with commercial antioxidant BHA (Butylated hydroxyl anisole) and BHT (Butylated hydroxyl toluene) in concentrate % 0.02 , in addition to the control sample (of crude sunflower oil without any additives) during 16 days storage at 60 C. The results showed an increase in the TBA values in sunflower oil, crude and stored in during storage at 16 days in 60 C. Some extracts laurels showed high anti-oxidant activity and more than commercial antioxidants (BHT) and (BHA). The results of the TBA transactions for crude extracts of plant concentration% 0.04 most efficient overall transactions in concentration % 0.02, aqueous extract of bay leaves in the concentration of % 0.04 showed high activity asan antioxidant with 2.88 mg Malonaldehyde / kg oil TBA value in the 16th and the last day of storage time in 60 C, while the TBA values of the rest of the coefficients of crude sunflower oil translate with plant extract :essential oil ethanolic alcohol and water extract in the concentration of 0.02% were 4.04, 3.39, 3.12 mg Malonaldehyde / kg oil, and in the concentration of 0.04% for essential oil ethanolic alcohol treatment were 4.01 and 2.29 mg Malonaldehyde / kg oil , respectively in the last day of storage, either control and commercial antioxidants BHA and BHT reached TBA values of crude oil 6.88, 3.16 and 3.50 mg Malonaldehyde/kg oil, respectively, in the same day of storage. Was estimated as the content of plant nutrients and mineral major and minor, were detected. Chemical quality of the active chemical compounds of plant leaves, which included tannin, Alclaicosadat, Alsabonyat, resins, phenols, flavonoids and alkaloids were evaluate to.
