Optimized phenolics from oregano and cranberry extracts were evaluated for antimicrobial activity against Listeria monocytogenes in laboratory media and in beef and fish. The antimicrobial activity increased when oregano and cranberry extracts were mixed at a ratio of 75% oregano and 25% cranberry (wt/wt) with 0.1 mg of phenolic per disk or ml, and the efficacy was further enhanced by lactic ac...

The active parts of 11 medicinal plants were analyzed for physico-chemical evaluation, phytochemical determination and antioxidant activity. The physico-chemical evaluation revealed that highest water soluble extractive was from Origanum vulgare (38%), highest chloroform extractive was from Psoralea corylifolia (21%); highest ethanolic extractive was that of Acorus calamus (11%) and the highest...

In the present investigation, we examined the cytotoxic effect of methanolic extract from Origanum vulgare on HCT-116 and MDA-MB-231 cell line in vitro. In order to determine the cytotoxic effects we used an MTT viability assay. The results showed that cell growth is significantly lower in extract treated cells compared to untreated control. The effect of inhibition of cell growth was higher in...

Two types of molecular markers, random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR), were assayed to determine the genetic diversity of 46 barley accessions, including 27 landraces of H. vulgare ssp vulgare (HV), 6 accessions of H. vulgare ssp. spontaneum (HS) and 13 accessions of H. vulgare ssp. agriocrithon (HA), from west China. A high level of polymorphism was fo...

 Background & Objective:  Toxico-pathological effects of herbal plants have always been a major concern, but little information is provided on the toxico-pathological effects of origanum on the fetus. Due to ethical rules and regulations, no drug experiment on the human fetus is permitted; hence, the chick embryo model is used as an ideal opportunity to study the adverse effects of drugs. This ...

Origanum vulgare L. (Lamiaceae) has been currently known for their interesting antimicrobial activity being regarded as alternative antimicrobial for use is food conservation systems. This study aimed to evaluate the effectiveness of O. vulgare essential oil in inhibiting the growth of some food-related Aspergillus species (A. flavus, A. parasiticus, A. terreus, A. ochraceus, A. fumigatus and A...

The aim of this study was to investigate antibacterial effects of oregano and thyme essential oils (EOs) on some food-borne bacteria. GC-MS analysis of EOs was performed in order to determine their composition and phenols were predominant constituents. The investigation of the antibacterial effects of EOs was performed on Salmonella Enteritidis, Salmonella Thyphimurium, Staphylococcus aureus, m...

Twelve essential oils from Mediterranean aromatic plants were tested for their phytotoxic activity, at different doses, against the germination and the initial radicle growth of seeds of Raphanus sativus, Lactuca sativa and Lepidium sativum. The essential oils were obtained from Hyssopus officinalis, Lavandula angustifolia, Majorana hortensis, Melissa officinalis, Ocimum basilicum, Origanum vul...

The present study was carried out to evaluate the antimicrobial potential of Artemisia sieversiana Ehrhart. Ex. Willd. (Asteraceae) and Origanum vulgare L. (Lamiaceae) from their extracts. Solvent ether, petroleum ether, chloroform, acetone, ethanol, benzene and aqueous extracts were tested against the test organisms viz., Bacterial strains (Escherichia coli and Bacillus subtilis) and fungal st...
