A Comparison of Antibacterial Effects of Catharanthus roseus and Camellia sinensis (Black Tea) and Their Synergistic Effect along with Antibiotic against Multiple Antibiotic Resistant Strains of Staphylococcus aureus
ABSTRACT Community associated strains of Staphylococcus aureus were isolated and treated with extracts of Catharanthus roseus and Camellia sinensis (black tea) to examine their antibacterial potential, either alone or in combination with an antibiotic, ampicillin. Results of MIC values (Minimum Inhibitory Concentration), growth inhibitory patterns, SEM images of the clinical and standard strains in the presence of their ethanolic extracts indicated that C. roseus root had greater antibacterial potential than black tea. The FIC (Fractional Inhibitory Concentration) values suggested that the combination of C. roseus root extract and ampicillin had a greater antibacterial activity due to a synergistic effect, than that of the combination of black tea and ampicillin, which exerted an additive effect.
期刊介绍：
The Journal of Herbs, Spices & Medicinal Plants is an essential reference filled with recent research and other valuable information associated with herbs, spices, and medicinal plants. The Journal serves as a focus point through which investigators and others may publish material of importance to the production, marketing, and utilization of these plants and associated extracts. The journal covers the following topics: growth, development, horticulture, ecology, physiology, genetics, chemistry, and economics. Original articles, review articles, and book reviews provide information of interest to an international audience of researchers, teachers, technicians, and managers involved with production and/or marketing of herbs, spices, and medicinal plants. Managers of food companies, food processing facilities, medical research laboratories, government agencies, and others interested in new chemicals, food additives, international trade, patents, and other items can easily review new findings. The Journal of Herbs, Spices & Medicinal Plants is a forum in which recent research and other information associated with herbs, spices, and medicinal plants is shared. The Journal represents a centralized database accessible by investigators within the international community that work with or have an interest in herbs, spices, and medicinal plants.
