“…The major component of obtained from Origanum onites was carvacrol (58.65%), followed by other components: Thymol (30.97%), Linalool (4.17%), p-Cymene (1.94%), γterpinene (0.95%) (Table 2). The most abundant carvacrol component was found to be the first most abundant compound in previous studies: 88.71% [47], 83.30% [91], 81.01% [92], 78.40% [50], 72.12% [93], 59.87% [94], 57.63% [49], 57.01% [79] 47.99% [95], 26.91% [96].…”

The use of chemical pesticides to protect agricultural products is a global concern because of their adverse effects on the environment and public health. To avoid the dangers of synthetic herbicides, research has turned to natural alternatives. This study was conducted to evaluate the allelopathic effect of essential oil (EO) extracted from Origanum syriacum, Origanum onites, and Origanum majorana. In addition, the chemical composition of the essential oil was elucidated by gas chromatography and mass spectrometry (GC–MS) analysis. A total of 11 different components of O.syriacum were identified, and the main components were carvacrol (88.49), p-Cymene (5.71), γ-Terpinene (1.63), β-Caryoplhyllene (1.48), and Terpinen-4-ol (0.65), respectively. For O. onites, 10 different compounds were identified, and the main components were carvacrol (58.65), Thymol (30.97), Linalool (4.17), p-Cymene (1.94), and β-Caryoplhyllene (0.98), respectively. Finally, for O. majorana, 14 different compounds were identified, and the main components were carvacrol (40.57), α-Terpineol (29.28), p-Cymene (9.02), γ-Terpinene (5.80), and carvacrol methyl ether (3.46). Finally, 14 compounds from the Origanum majorana species were identified, with carvacrol (40.57), -Terpineol (29.28), p-Cymene (9.02), and -Terpinene (5.80) as the parent compound (3.46). Oxygenated monoterpenes were the highest in all species’ EO content. EOs and plant extracts were tested at 5, 10, and 20 L/Petri concentrations against seed germination and seedling growth in four weed species (Thlaspi arvense, Amaranthus retroflexus, Rumex cripus, and Lactuca serriola). The concentrations of essential oil were set as 5, 10, and 20 µL/Petri dishes for seed germination. In the greenhouse experiment, the final concentration of solutions was set as 20 µL and the solutions were directly sprayed on the surface of the weeds, and the mortality rates were noted after 24 and 48 h of application. It was observed that increasing the application decreased seed germination. The phytotoxic effects on the seedling germination in the greenhouse were observed, resulting in 48.76–94% mortality rates. Consequently, the essential oil from Origanum species could be considered as an alternative bio-herbicide to tested weeds.

“…Hem besin hem de halk ilacı olarak kullanılan Lamieceae familyasına ait olan farklı cinslerdeki birçok tür kekik adıyla anılmaktadır (Tuzlacı, 2011). Bu türlerin neredeyse tamamında timol bulunmaktadır (Sarıkaya, 2019). Yapılan araştırmalarda özellikle oksidatif stresle ilişkili olan birçok hastalıktan korunmak için fenolik bileşikler açısından zengin besin öğelerinin diyete dahil edilmesi önerilmektedir (Roleira ve ark., 2015;Yılmaz ve ark., 2019).…”

Thyme is one of the spices that is widely consumed in the regions where it grows and is used in many dishes, especially soups, and gives a regional identity to the dish where it is used. In this study, the amount of phytochemicals and antioxidant capacity of the plant Satureja hortensis L. (süpürge kekiği, çibriska) which grows spontaneously and is used as a spice in meals in the Karakoçlar settlement area of Olur district of Erzurum province was investigated. The total amounts of phenolic and flavonoid substances were determined to be 40.85±0.85 mg GAE/g and 26.52±0.46 mg QE/g, respectively. In addition, the DPPH radical scavenging activity of the plant extract was calculated as 45.24 ±3.47 μg TE/mL and the IC50 value was calculated as 177.11±0.99 μg/mL. It was determined that the Cu2+ reducing antioxidant capacity of the S. hortensis plant extract was 2162.09±113.61 μg TE/mL and the Fe3+ reducing antioxidant capacity was 24.36±4.59 μg TE/mL. As a result, it was concluded that the S. hortensis plant, which is known with different names in different regions, has antioxidant potential and can be used as a natural antioxidant source in addition to its common use.
