Treatments for bovine mastitis based on antibiotic therapy are not always effective which may lead to faults in recovery of diseased animals, selection of resistant bacteria and the presence of antimicrobial residues in milk. In this context the use of essential oils configures as an alternative to control mastitis pathogens in dairy cows because they have antibacterial action against gram-posi...

Five Indian medicinal plants namely Acorus calamus L, Pelargonium graveolens L, Cymbopogon martini L, Cyambopogon nardus L and Cymbopogon citratus L. were studied for their enzymatic and non enzymatic free radical scavenging properties. Enzymatic ROS scavengers: superoxide dismutase (SOD) and catalase were observed maximum respectively in A. calamus (3.59±0.22 μ mol/min/mg/protein) and P. grave...

The study assessed the growth inhibitory effects of essential oils extracted from ten Ugandan medicinal plants (Bidens pilosa, Helichrysum odoratissimum, Vernonia amygdalina, Hoslundia opposita, Ocimum gratissimum, Cymbopogon citratus, Cymbopogon nardus, Teclea nobilis, Zanthoxylum chalybeum, and Lantana trifolia) used traditionally in the management of oral diseases against oral pathogens. Che...

The efficacy of extracts and essential oils from Allium tuberosum, Coriandrum sativum, Cymbopogon martini, Cymbopogon winterianus, and Santolina chamaecyparissus was evaluated against Candida spp. isolates from the oral cavity of patients with periodontal disease. The most active oil was fractionated and tested against C. albicans biofilm formation. The oils were obtained by water-distillation ...

Generally, the medicinal plants have antifungal substances that can be used for the plant protection against phytopathogens. The objective of this study was to know the efficiency of aqueous extracts from medicinal plants against the major etiological agents of coffee tree. The aqueous extracts used were extracted from bulbs of Allium sativum, leaves of Vernonia polysphaera, Cymbopogon citratus...

Background and objectives: Phlomis olivieri Benth. (Lamiaceae) is a medicinal plant widely distributed in Iran. In the present study, we have investigated the phytochemical constituents, antioxidant activity and general toxicity potential of the aerial parts of this species. Methods: Silica gel (normal and reversed phases) and Sephadex LH-20 colu...

AIMS To compare the bacteriostatic and bactericidal activity of 13 chemotyped essential oils (EO) on 65 bacteria with varying sensitivity to antibiotics. METHODS AND RESULTS Fifty-five bacterial strains were tested with two methods used for evaluation of antimicrobial activity (CLSI recommendations): the agar dilution method and the time-killing curve method. EO containing aldehydes (Cinnamom...

Oils extracted from fifteen medicinal plants were screened for their activity against A. fumigatus and A. niger by disc diffusion method. Minimum inhibitory concentrations (MICs) of oils (%v/v) against Aspergillus fumigatus and Aspergillus niger done by agar dilution method and minimum inhibitory concentration (MIC) and minimum cidal concentration (MCCs) data (%v/v) obtained by the broth micro ...
