1,1-Dipehnyl-2-picrylhydrazyl (DPPH) radical scavenging activities were found in the extract of dried leaves of oregano (Origanum vulgare). The water-soluble active ingredients were isolated, and their structures were determined to be 4'-O-beta-D-glucopyranosyl-3',4'-dihydroxybenzyl protocatechuate and 4'-O-beta-D-glucopyranosyl-3',4'-dihydroxybenzyl 4-O-methylprotocatechuate by (1)H-, (13)C-NM...

BACKGROUND Elicitation, which is a way of inducing plant secondary metabolism, may be an effective method for improving the quality of plant food. The aim of this study was to determine how the application of jasmonic acid (as an abiotic elicitor) and yeast extract (as a biotic elicitor) influences the production of some bioactive compounds in marjoram and the antioxidant activity of this herb....

The aim of this study was to evaluate the dietary effect of feeding pigs with diets enriched with sweet chestnut wood (Castanea sativa Mill.) or oregano (Origanum vulgaris L.) extract on the microbiological and chemical characteristics of cooked pork ham. Three groups of 10 pigs were fed with a control diet (CTRL), with the CTRL diet enriched with 0.2% of oregano extract (OR) and with the CTRL ...

Type 1 diabetes (T1D), an autoimmune inflammatory disorder, develops as a consequence of pancreatic β-cell destruction and results in hyperglycaemia. Since current T1D therapy mainly involves insulin replacement, the aim of the present study was to evaluate the therapeutic potential of Origanum vulgare L. ssp. hirtum (Greek oregano) leaf extract rich in biophenols for the treatment of T1D. The ...

Of 17 spices and herbs tested at 1% (wt/vol) in Mueller-Hinton (MH) agar, only cloves, thyme, oregano, allspice, basil, rosemary, and marjoram showed antimicrobial effects on Shigella. The MICs of thyme, oregano, basil, and rosemary (as determined by the agar dilution method) ranged from 0.5 to 1% (wt/vol) depending on the Shigella strain used. With the use of various combinations of temperatur...

The potential of plant essential oils (EOs) in anticancer treatment has recently received many research efforts to overcome the development of multidrug resistance and their negative side effects. The aims of the current research are to study (i) the cytotoxic effect of the crude EO extracted from Origanum vulgare subsp hirtum and its main constituents (carvacrol, thymol, citral and limonene) o...

Background: Many plants possess therapeutic properties against infectious and non-infectious diseases, including cancer inflammatory diseases. Plants may have immunomodulatory properties, too. In this study, we evaluated the effects toxic of ethanolic extract from Lamiaceae family on macrophage, lymphocyte, B Cell Leukemia (BCL-1) in vitro. Materials Methods: Plant samples were purchased, their...

In vitro antimicrobial and antibiofilm forming activities of Origanum munzurense extract were investigated against some gram-positive bacteria yeast strains. Liquid microdilution method microplate used for activities, respectively. Minimal inhibitory concentration values found to be 2 mg/ml Enterococcus faecalis ATCC 29212, 64 Listeria monocytogenes RSKK 02028, L. 472, Bacillus cereus NRRL 569 ...

Tuberculosis (TB) is a communicative disease caused by Mycobacterium tuberculosis bacteria that may cause death if it is left untreated. WHO (2010) recommended standard drugs as first line anti-tuberculosis (anti-TB) therapy involved (HRZE): isoniazid (H), rifampicin (R), pyrazinamide (Z) and ethambutol (E) received as a fixed dose combination suspension according to the body weight.
