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...

Gri küf hastalığına neden olan Botrytis cinerea aralarında turunçgil meyvelerininde bulunduğu oldukça geniş konukçu dizisine sahip fungal bir hastalık etmenidir. Bu çalışmada farklı kekik türleri (Origanum onites L., Origanum syriacum Holm., Thymbra spicata L.) ve rezene (Foeniculum vulgare Mill.) bitkilerinden elde edilen uçucu yağların cinerea’nın misel gelişimi, spor çimlenmesi hiflerinin mo...

Essential oils from oregano (Origanum vulgare L.), mint (Mentha piperita L.), fennel (Foeniculum vulgare Mill.), and pine (Abies alba Mill.) needles and cones, and their active substances thymol, carvacrol, menthol, and anisaldehyde were tested for antifungal activity against Penicillium verrucosum. The lowest minimal inhibitory concentrations (MICs) were achieved for essential oil of oregano, ...

Background: Hydatidosis is a common disease of both humans and animals, resulting from infection with the larvae of Echinococcus granulosus tapeworm. The aim of this study was to investigate the antiparasitic (protoscolicidal) activities of three essential oils in vitro. Methods: This study was designed to evaluate the biochemical composition and in vitro antiparasitic effects of Zataria multi...

The insecticidal activity of essential oils isolated from two species of Origanum (Origanum onites L. and Origanum minutiflorum (O. Schwarz and P.H. Davis) (Labiate)) was investigated against 3rd and 4th instar larvae of the mosquito, Culex pipiens L. (Diptera: Culicidae). The LC50 and LC90 values were 24.8 and 61.3 ppm, and 73.8 and 118.9 ppm, respectively. This activity was attributed to the ...

the objective of the present investigation was to assess the possible involvement ofgabaergic mechanism in analgesic effect of aqueous extract of origanum vulgare (org)in a rat model of acute pain test. sixty-three anaesthetized male wistar rats (200-250 g) werecannulated into the left ventricle. five to seven days after the recovery from surgery, org extractwas intraventricularly injected at d...
