An improved method of sample preparation was used in a microplate assay to evaluate the bactericidal activity levels of 96 essential oils and 23 oil compounds against Campylobacter jejuni, Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella enterica obtained from food and clinical sources. Bactericidal activity (BA50) was defined as the percentage of the sample in the assay mixture...

Investigated six plant extracts viz.,, kaner leaf extract (Nerium indicum), khejri leaf extract (Prosopis cineraria), neem leaf extract (Azadirachta indica), safeda leaf extract (Eucalyptus globulus), tomato leaf extract (Lycopersicum esculentum) and mustard seed extract (Brassica compestris) and four plant powders viz.,, black pepper powder (Piper nigrum), garlic clove powder (Allium sativum),...

The inhibitory effects of essential oils including clove, lavender and geranium extracted from Eugenia caryophyllata, Lavandula officinalis and Pelargonium graveolens on multidrug resistant isolates of Pseudomonas aeruginosa were investigated. The main constituents of clove, lavander and geranium oil were eugenol (80-90%), 1,8-cineol (13%) and citronellol (45%) respectively. Clove had the most ...

BACKGROUND The current study investigates the anti-stress effects of clove (Eugenia caryophyllus) extracts (0, 200, 400, and 600 mg/kg) on serum antioxidant biomarkers, immune response, immunological organ growth index, and expression levels of acute phase proteins (APPs); ovotransferrin (OVT), ceruloplasmin (CP), ceruloplasmin (AGP), C-reactive protein (CRP), and serum amyloid-A (SAA) mRNA in ...

OBJECTIVE The beneficial effects of clove on toothache have been well documented. We have also previously shown the analgesic effects of clove essential oil. The present work was done to investigate the analgesic effects of the aqueous extract of clove using hot plate test. The possible role of opioid receptors in the analgesic effects of clove was also investigated using naloxone. MATERIALS ...

The developmental toxicity of two anaesthetics, 2-phenoxyethanol and clove oil, used in aquaculture was evaluated using the Frog Embryo Teratogenesis Assay: Xenopus (FETAX) and the results were compared to outcomes in fish. Xenopus laevis embryos were exposed to 50, 100, 300, 500, 700 and 1000 mg/l of 2-phenoxyethanol or 1, 5, 10, 20, 30 and 40 mg/l of clove oil. Values of 96 h LC50, 96 h EC50 ...

Clove oil inhibited human platelet aggregation induced by arachidonic acid (AA), platelet-activating factor (PAF) or collagen. Clove oil was a more effective inhibitor for aggregation induced by AA and PAF (IC50:4 and 6 microM respectively) than collagen (IC50: 132 microM). The in vivo experiments in rabbits showed that clove oil (50-100 mg/kg) afforded 100% protection against PAF (11 mg/kg, i....

Clove mistletoe (Dendrophthoe pentandra (L.) Miq.) is a semiparasitic plant that belongs to Loranthaceae family. Clove mistletoe was traditionally used for cancer treatment in Indonesia. In the present study, we examined cytotoxicity of clove mistletoe leaves extracts against brine shrimps and conducted their antiproliferative activity on K562 (human chronic myelogenous leukemia) and MCM-B2 (ca...

OBJECTIVE The present study was undertaken to evaluate the anti-stress effect of the hydro-alcoholic extract of clove. METHODOLOGY The anti-stress effect was evaluated on cold restraint induced gastric ulcers, sound stress induced biochemical changes and anoxic stress induced convulsions. Clove extract was administered orally at two different doses of 100 and 200 mg/kg. Zeetress, a known anti...
