“…The leaves and dried herbs of oregano have been used for medical purposes for centuries (Chun et al, 2005). Recent research has shown that oregano extracts, among all aromatic herbs, have the most effective antioxidant activity and antimicrobial properties (Milos et al, 2000;Kouri et al, 2007) and that oregano is used as an antidiabetic, carminative, tonic, stimulant, diuretic and to treat asthma (nakiboglu et al, 2007). Recently, there is an increasing interest in finding natural antimicrobials from different extracts obtained from plant materials.…”

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...

Introduction: Mentha pulegium L. and Matricaria chamomilla L. are used in the Algerian folk medicine. This study was carried out to determine the antioxidant activity of these plants and their polyphenols contents. Methods:The antioxidant capacity of the plant extracts was determined by the scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and β-carotene/linoleic acid model system. Total phenolic content in these extracts were determined using Folin-Ciocalteu's reagent. Results: The methanolic extract (MeE) of Mentha pulegium L. showed the highest yield of extraction (14.4%). Whereas, the aqueous extract (AqE) of Matricaria chamomilla L. had the highest yield (18.56%) from total extracted plant material. Moreover, the ethyl acetate extract of Mentha pulegium L. contains high amount of total polyphenols; tannins and flavonoids (191.99 µg gallic acid equivalent/g dry extract; 265.33 µg tannic acid equivalent/g dry extract; 110.37 µg quercetin equivalent/g dry extract; 151.11 µg rutin equivalent/g dry extract) respectively. This extract possessed high antioxidant activity (IC 50 =0.017 mg/ml) in the DPPH assay whilst the chloroformic extract (ChE) is more efficient in the β carotene/linoleic acid assay with (61.07%). The ChE of M. chamomilla contains the higher value of flavonoids (197.43 µg quercetin equivalent/g) and total polyphenols were abundant in MeE. The ethyl acetate extract of this plant had the highest antioxidant activity (IC 50 = 0.0111 mg/ml) in the DPPH assay, while chloroformic extract shows appreciable inhibition value (37.15%) in the β carotene/linoleic acid assay. Conclusion: These results provide useful information about the utilization of these plants as natural antioxidants in food and in folk medicine.

In this study, the biological activity of selected Greek medicinal and aromatic plants on the phytopathogenic fungus Alternaria alternata was investigated. Biological activity was screened on crude aqueous extracts and their aqueous phase (ap-pt) after further extraction with petroleum ether. All the Lamiaceae species examined were found to enhance significantly the mycelium growth. Melissa officinalis extracts caused the highest stimulation in mycelium growth, (+109.1%) the ap-pt, and (+51.6%) its crude extract. All ap-pt extracts stimulated conidia production, but Melissa officinalis caused the highest effect (+349.3%). Crude extracts of Salvia officinalis stimulated highly conidial production (+65%) whereas Hyssopus. officinalis and Origanum vulgare inhibited conidia production at 33.3% and 50.0% respectively. The differences in biological activity between crude and ap-pt extracts for each plant species were attributed through the calculation of correspondent synergism ratios (SR) to the interaction between volatile and water -soluble. Rosmarinic acid, detected as the most abundant phenolic compound in all extracts analyzed and found to correlate strongly (R= 0.84) with the stimulation effect on spore production of A. alternata.
