INTRODUCTION The role of Origanum ehrenberjii against bacteria that cause enteric diseases is well known. Salmonella and Enterococcus cause high rates of enteric infections around the world. The aim of this study was to extract essential oils from cultivated and naturally growing O. ehrenberjii, compare the chemical profiles of the extracts and estimate their antimicrobial efficacy against ente...

Plants have been used for medical purposes since the beginning of human history and are the basis of modern medicine. Most chemotherapeutic drugs for cancer treatment are molecules identified and isolated from plants or their synthetic derivatives. Our hypothesis was that whole plant extracts selected according to ethnobotanical sources of historical use might contain multiple molecules with an...

The antifungal effect of twenty powdered spice plants and their extracts at concentrations of 2, 4, 8 and 1, 3, 6%, respectively was evaluated in relation to the radial mycelial growth of various soilborne fungi causing damping-off disease. The spice powder or extract were added to the culture medium PDA to obtain the proposed concentrations. Concentration of 8% of powdered spices and 6% of the...

background: in current study, chemical composition and antibacterial activity of leaves and flowers essential oils of origanum vulgare ssp. gracile against four food-borne pathogens including  escherichia coli, listeria monocytogenes, salmonella thyphimurium and staphylococcus aureus were examined. methods: the different organs (leaves and flowers) of o. vulgare ssp. gracile were harvested at f...

background: herbal essential oils (eos) are natural, volatile, and complex compounds that are defined by a strong odor. this study was conducted to investigate and compare antioxidant and antifungal properties of eo extracted from flowers and leaves of origanum vulgare ssp. gracile from iran. methods: eos of leaves and flowers of o. vulgare ssp. gracile were extracted using a modified clevenger...

The present study was conducted to test the effect of Origanum Majoranum Extract (OME) of leaves on alterations induced in a model of type 2 diabetic rats. Adult male Wistar rats were fed high fat diet for 3 weeks and injected a single dose of streptozotocin (35 mg/kg) intraperitoneally to induce type 2 diabetic rats. Diabetic rats were given aqueous extract of OME in a dose of 20 mg/kg orally ...

Background and Objectives: Essential oils are very complex mixture of components and their composition may vary in different species or varieties or even within the same variety. Origanum vulgare L. subsp. vulgare is one of the most distributed subspecies within the genus Origanum and has been found to be a poor-oil, categorized in cymyl, bornane or sabinyl chemotypes with higher proportion of ...

Food Sci., 28: 317–325. The antioxidant capacity of some herbs used in dietology practice was determined by the DPPH free radical method, which was calibrated with ascorbic acid. Partially hydrophilic phenolic comp...

background: wound infection has become a major medical problem in recent years. this is usually caused by gram-positive bacteria, especially staphylococcus aureus. since antimicrobial resistance to current drugs has critically been developed in these causative microorganisms, substitution medicine has become one of the main interests within  researchers. objectives: the aim of this study was to...

The essential oils obtained from the aerial parts of Origanum scabrum and Origaum microphyllum, both endemic species in Greece, were analyzed by means of GC and GC-MS. Forty-eight constituents were identified, representing 98.59 and 98.66% of the oils, respectively. Carvacrol, terpinen-4-ol, linalool, sabinene, alpha-terpinene, and gamma-terpinene were found as the major components. Furthermore...
