Unravelling the Chemotaxonomic Identity of “White” and “Black” Oregano (Origanum vulgare) in Northern Greece
Planta Med DOI: 10.1055/a-1949-8895The two types of oregano used by the inhabitants of the villages of Μount Belles (GR1260001), the “white” oregano with white flowers and “black” oregano with purple flowers, were studied.
The two oregano types were collected from five localities along an altitudinal gradient from 217 m up to 1299 m. “White” oregano, was found in the three lowland regions (up to 752 m) where
the Pannonian-Balkanic turkey oak-sessile oak forest habitat (code 91M0) dominates. The “black” oregano was collected from the two higher altitudes, at 1177 m and 1299 m, where the

Essential oils of four wild plants inhibit the blood seeking behaviour of female Aedes aegytpi
Exp Parasitol. 2022 Nov 11:108424. doi: 10.1016/j.exppara.2022.108424. Online ahead of print.ABSTRACTAedes aegypti (Diptera: Culicidae) mosquito is an important vector of many disease-causing pathogens. An effective way to escape from these mosquito-borne diseases is to prevent mosquito bites. In the current study, essential oils of Lepidium pinnatifidum, Mentha longifolia, Origanum vulgare, and Agrimonia eupatoria were evaluated for their repellent potential against Ae. aegypti females. Essential oils were extracted using steam distillation from freshly collected aerial parts of the plants and tested against 4-5 day old f...

Investigation of antimicrobial activities and molecular characterization of the species belong to Origanum, Thymus and Thymbra genera by ISSR
CONCLUSION: Staphylococcus aureus was the most sensitive and Pseudomonas aeruginosa was the least sensitive strain. The ethanol and chloroform extracts were the most effective solvents. ISSR markers were successful for determining high levels of genetic diversity and clustering the species belonging to the genera Origanum, Thymus, and Thymbra. Conducting molecular marker analyses facilitated in distinguishing the species correctly for molecular breeding studies. The studies identified the antimicrobial activities of the plants against the bacteria used in the study and suggested their potential role in the pharmaceutical i...

Origanum vulgare ethanolic extracts as a promising source of compounds with antimicrobial, anti-biofilm, and anti-virulence activity against dental plaque bacteria
Dental caries and periodontal diseases remain a challenge for oral health, especially given the lack of effective and safe treatment options that are currently available. Against the backdrop of an ongoing antimicrobial resistance crisis, a renewed interest in traditional medicinal plants as a potential source of new bioactive compounds has surfaced. In this context, we systematically screened the antimicrobial and anti-biofilm activities of both ethanolic and aqueous extracts of nine Algerian medicinal plants (Artemisia herba alba, Centaurium erythraea, Juglans regia, Laurus nobilis, Matricaria recutita, Mentha pulegium, ...

Molecules, Vol. 27, Pages 7335: Chemical Profiling and Biological Activity of Extracts from Nine Norwegian Medicinal and Aromatic Plants
s Rosnes
There is an increased interest in identifying beneficial compounds of plant origin that can be added to animal diets to improve animal performance and have a health-promoting effect. In the present study, nine herb species of the Norwegian wild flora or which can be cultivated in Norway were selected for phytogenic evaluation (hops, maral root, mint, oregano, purslane, rosemary, roseroot, sweet wormwood, yarrow). Dried herbs were sequentially extracted with dichloromethane (DCM), ethanol (EtOH) and finally water (H2O) by ultrasound-assisted extraction (UAE). The UAE protocol was found to be more rational than ...

Genes, Vol. 13, Pages 1844: Evaluation of the Maturity and Gene Expression of Sheep Oocytes and Embryos Cultured in Media Supplemented with Marjoram (Origanum vulgare) Extract
This study aimed to evaluate the effects of marjoram extract on oocyte maturation and gene expression in sheep oocytes and embryos. The first experiment studied the effect of the extract as an antioxidant to improve the in vitro maturation media used for sheep oocytes; the oocytes were matured in a TCM199 medium supplemented with 1 or 10 µg/mL of marjoram extract or the control, 0 µg, for 24 hr. Then, the maturation was estimated, and the gene expression was measured by using qPCR. The second experiment studied the effect of the extract on the development of sheep embryos produced in vitro; the ...

Molecules, Vol. 27, Pages 6702: Comparison of Origanum Essential Oil Chemical Compounds and Their Antibacterial Activity against Cronobacter sakazakii
Li
Lei Shi
Origanum vulgare L. (oregano) is an aromatic plant with wide applications in the food and pharmaceutical industries. Cronobacter sakazakii, which has a high detection rate in powdered infant formula, adversely impacts susceptible individuals. Oregano essential oil (OEO) is a natural antibacterial agent that can be used to fight bacterial contamination. Here, OEO chemical compounds from eight oregano varieties were analyzed by gas chromatography–mass spectrometry and their antibacterial properties were assessed. The eight OEOs were clustered into two groups and were more diverse in group 2 th...
