Assessment of Antioxidant, Antibacterial, and Preliminary Cytotoxic Properties of Brownlowia Tersa
ABSTRACT Antioxidant, antibacterial, and brine shrimp lethality bioassay of Brownlowia tersa leaf and bark extracts were performed. The half maximal inhibitory concentration (IC50) values in DPPH free radical scavenging assay for the bark and leaf extracts of petroleum ether, chloroform, and methanol were 102.09 ± 0.53, 236.28 ± 0.85, 27.90 ± 0.56, and 183.74 ± 0.75, 45.78 ± 0.27, and 35.12 ± 0.55 µg mL−1, respectively. Total phenolic content was the higher in methanolic bark and leaf extracts than in other solvents. Total flavonoid content was the highest in the methanolic leaf extracts and the lowest in chloroform bark extract. Petroleum ether and methanolic extracts of bark and leaf demonstrated antibacterial activity against Escherichia coli ATCC 28739 and Pseudomonas aeruginosa ATCC 27833.
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.
