Antioxidant and antimicrobial activity in the seeds of <i>Origanum vulgare</i> L. subsp. <i>gracile</i> (C. Koch) Ietswaart and <i>Origanum acutidens</i> (Hand.-Mazz.) Ietswaart from Turkey

Abstract

RESUMENEn el presente estudio se han determinado algunos compuestos biológicos (ácidos grasos, vitaminas, esteroles y flavonoides), la capacidad de secuestrar radicales libres y la actividad antimicrobiana de dos especies de orégano, Origanum vulgare L. subsp. gracile (C. Koch) Ietswaart y Origanum acutidens (Hand.-Mazz.) Ietswaart. El ácido linolénico (C 18:3 ) mostró ser el principal ácido graso en ambas especies, seguido por los ácidos palmítico (C 16:0 ), esteárico (C 18:0 ), oleico (C 18:1 n9), linoleico (C 18:2 n6) y estearidónico (C 18:4 ). Además, las dos especies de orégano mostraron contener altos niveles de estigmasterol. También se constató que Origanum vulgare L. subsp. gracile (C. Koch) Ietswaart tenía un elevado contenido de β-sitosterol (152,8  2,6 mg / g), gran cantidad de vitaminas D3 (33,1  0,8 mg / g), K1 (29,4  0,8 mg / g), K2 (26,0  0,8 g / g), y bajos contenidos de α-tocoferol (7,8  0,2 mg / g) y vitamina D2 (1,8  0,1 mg / g), mientras que Origanum acutidens (Hand.-Mazz) Ietswaart contenía altas concentraciones de vitamina D2 (42,9.  1,5 mg / g), y bajas concentraciones de D3 (2,9  0,1 mg / g), α-tocoferol (3,1  0,1 mg / g), γ-tocoferol (3,5  0,2 mg / g), K2 (1.3  0,1 mg / g), acetato de retinol (1,3  0,2 mg / g) y retinol (1,2  0,1 mg / g). El presente estudio también mostró que Origanum vulgare L. subsp. gracile (C. Koch) Ietswaart y Origanum acutidens (mano.-Mazz.) Ietswaart contenían pequeñas concentraciones de flavonoides. Por otra parte, los extractos de metanol mostraron ser el agente más eficaz contra radicales DPPH en ambas especies de orégano examinados. Los resultados experimentales mostraron que las vitaminas, flavonoides y áci-dos grasos de los extractos de ambas especies de orégano fueron eficaces -a diferentes niveles-en la inhibición del crecimiento de los microorganismos ensayados. The present study determined some biological compounds (fatty acids, vitamins, sterols and flavonoids), radical scavenging capacity and antimicrobial activity of two Origanum L. species of Origanum vulgare L. subsp. gracile (C. Koch) Ietswaart and Origanum acutidens (Hand.-Mazz.). Ietswaart. Linolenic acid was found to be the main fatty acid in both species, which was followed by palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1 n9), linoleic acid (C18:2 n6) and stearidonic acid (C18:4). In addition, the two Origanum species were recorded as containing high levels of stigmasterol. It was also found that Origanum vulgare L. subsp. gracile (C. Koch) Ietswaart had a high β-sitosterol content (152.82.6 µg/g); high amounts of D3 (33.10.8 µg/g), K1 (29.40.8 µg/g), K2 (26.00.8 µg/g) vitamins; and low amounts of α-tocopherol (7.80.2 µg/g) and D2 (1.80.1 µg/g), while Origanum acutidens (Hand.-Mazz.) Ietswaart contained high amounts of D2 (42.91.5 µg/g) vitamin; and low amounts of D3 (2.90.1 µg/g), α-tocopherol (3.10.1 µg/g), r-tocopherol (3.50.2 µg/g), K2 (1.30.1 µg/g), retinol (1.30.2 µg/g) and retinol acetate (1.20.1 µg/g) vitamins. The present study showed that O...

“…After 30 minutes of darkness and room temperature, samples were read at 517 nm in a spectrophotometer. DPPH• Radical Sweep Percentage % = [(A0 -A1)/A0] x 100 A0: Control absorbance, A1: Sample absorbance (Kürşat et al, 2011).…”

“…It was discovered that it was 220 nm for retinol acetate. The Class Vp 6.1 program was used, and the findings were expressed in terms of g/g (Bahşi, 2008;Kürşat et al, 2011).…”

Effects of essential oils obtained from wild and cultured forms of thyme (Origanum acutidens) on lung cancer cells membrane

“…The essential oils from wild and cultured form of Salvia pisidica showed cytotoxicity on H1299 cells24. In other studies, it has been reported that O. acutidens essential oil showed antimicrobial activity against different bacterial species(20,21).By culturing endemic species in different physical conditions, we can make them show similarities with the wild form. It has been reported in many studies that essential oils and their components obtained from plants had anticancer effects by creating cytotoxic effects on cancer cells.…”

Origanum heracleoticum Essential Oils: Chemical Composition, Phytotoxic and Alpha-Amylase Inhibitory Activities

“…Among traditional medical uses of the Origanum species, the treatment of abdominal pain, toothache, headache, diabetes, infections of the urinary tract, gastrointestinal and pulmonary diseases was reported [ 12 , 13 , 14 ]. Previous studies have shown antibacterial, antifungal, anticancer, antidiabetic, antinociceptive, insecticidal and phytotoxic activities for some Origanum species [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Interestingly, their essential oils (EOs) also showed ferric reducing and antioxidant properties [ 22 ].…”
