“…To the best of our knowledge, no previous studies have assessed the antioxidant potency of the organic extracts of O ehrenbergii . A recent study, conducted by Özer et al, 16 showed that the IC 50 of the MeOH extract of O boissieri was 91.99 μg/mL. Therefore, its antioxidant potency was less important than that of the MeOH extract of O ehrenbergii (IC 50 : 37.5 μg/mL).…”

“…Özer et al 16 tested the anti‐AchE activity of six Origanum species: O boissieri , O solymicum , O sipyleum , O saccatum , O ayliniae, and O hypericifolium . They found that the optimal inhibition of the AchE was registered with the MeOH extract of O hypericifolium (54.9%) at 200 μg/mL, which was four times more concentrated than the MeOH extract of O ehrenbergii used in the current study 16 . The latter tested at 50 μg/mL gave an inhibition percentage of 56.9% showing that its anti‐AchE activity was much more important.…”

Origanum ehrenbergii Boiss, endemic to Lebanon, is widely used in culinary preparations. The aim of this study is to assess the chemical composition and biological activities of four extracts obtained by consecutive extractions with four different solvents presenting an increasing polarity (cyclohexane, dichloromethane, ethyl acetate, and methanol). HPLC‐DAD analysis revealed nine compounds with 8 phenolics, while GC‐MS analysis allowed to detect 96 volatile compounds. Among the latter, some compounds were identified for the first time in plant extracts such as 2‐allyl‐phenyl tiglate (26); 2‐furylmethyl octanoate (28); 1H‐cycloprop[e]azulen‐7‐ol,decahydro‐1,1,7‐trimethyl‐4‐methylene‐,[1ar‐(1aα,4aα,7β,7aβ,7bα)] (30); 2‐(Z)‐propenylphenyl tiglate (32); 6‐hydroxy‐4,4,7a‐trimethyl‐5,6,7,7a‐tetrahydrobenzofuran‐2(4H)‐one (33); ent‐beyerane (37); and (E)‐2‐tridecenyl angelate (40). The methanol extract had the highest antioxidant activity with an IC50 of 37.5 μg/mL. It also had the highest phenolic content with 207.2 mg of gallic acid equivalents (GAE)/g of dry weight. The inhibition percentage of the acetylcholinesterase by the methanol extract (56.9%), the ethyl acetate extract (58.6%), and the cyclohexane extract (60.0%) was almost the same at 50 µg/mL. Furthermore, the dichloromethane extract inhibited both the growth of the MCF‐7 cell line by 67.0% and HCT‐116 cell line by 35.7% at 50 μg/mL. The MIC of the dichloromethane extract against Listeria monocytogenes ATCC 19 115 and Listeria monocytogenes isolated from “fish filet” was 4 and 15 μg/mL, respectively, and that of the cyclohexane extract against Staphylococcus aureus was 19.5 μg/mL.

“…Por ejemplo, la actividad broncodilatadora, tranquilizante, hipotensiva y antiinflamatoria atribuida a su aceite esencial [1,3,4]. Además, es amplia la evidencia respecto a su actividad antioxidante [4][5][6], considerando la creciente demanda actual por este tipo de alimentos que contribuyan a la prevención de enfermedades relacionadas con el estrés oxidativo [7], gracias a su contenido de compuestos flavonoides como quercetagetina y sus derivados glucosídicos y galactosídicos, patuletina, patuletina-7-glucósido, isoramnetina, entre otros [8,9].…”

The aim of the study was to evaluate the effect of three kinds of drying: tunnel drying (at 50, 60 and 70 °C), freezedrying (secondary drying at 40, 55 and 70 °C) and spray-drying (at 150, 160 and 170 °C) on the antioxidant capacity and phenolic compounds on huacatay (Tagetes minuta) leaves. Besides, for spraydrying, leave extracts were prepared (5 % soluble solids), and then, dried by a spray system by using two encapsulants: maltodextrin (10 dextrose equivalents, DE) and modified starch, at concentrations of 0.0, 0.5 and 1.5%. The antioxidant activity and phenolic content were measured by DPPH and Folin-Ciocalteu methods. In the samples subjected to tunnel drying (50, 60 and 70 °C) retention rates of antioxidant capacity of 40.

“…genera of the Lamiaceae family, such as the genus Origanum, have species with high antioxidant and antimicrobial activity(Alvarez, Ortega-Ramirez, Silva-Espinoza, Gonzalez-Aguilar, & Ayala-Zavala, 2019;Mahmoudi & Nosratpour, 2013;Özer et al, 2020;Sarikurkcu et al, 2015).Because of these activities (antioxidant and antimicrobial), in recent years, researchers have mostly gone through the researching the mechanisms of essential oils to prevent food spoilage by basing on these properties of the plants (Ehsani & Mahmoudi, 2013; Mahmoudi et al, 2019; Mahmoudi, Zare, Hassanzadeh, & Nosratpour, 2014; Mohammadzadeh, Mahmoudi, & Ghajarbeygi, 2018). Both enzymatic and microbiological food spoilages are of great importance in terms of their adverse effects on human health and economic losses in the food industry.…”

Origanum L. is one of the high-value medicinal and aromatic plants generally used for various purposes in the field of food and health. This study evaluated the effect of aqueous extract, hydrosol and essential oil forms of seven Origanum taxa including three endemic species in fresh-cut mushroom samples in order to prevent polyphenol oxidase (PPO) activity. Food samples were treated with these natural preservatives (aqueous extract, hydrosol, and essantial oil) and stored at 4°C temperature for a maximum of 5 days. It was found that the extract form of Origanum vulgare L. subsp. hirtum (Link) Ietsw. provided maximum PPO inhibition with 64.50% of reduction on 3rd day. Similarly, 3-fold reduction in hydrosol application was observed with Origanum bilgeri P. H. Davis which is the endemic plant. These results were conducted with the extract forms containing water are more effective than essential oil form to inhibit PPO activity. Practical applications In this study, we have investigated alternative usage of some Origanum plants as natural anti-browning food additives in mushroom samples. The samples separately treated with aqueous extract, hydrosol, and essential oil forms of different Origanum plants were stored until 5 days. PPO activities of samples on 1st, 3rd, and 5th days were used to determinate the shelf life of mushrooms associating with their browness.
