In Vitro Antioxidant Activity and Antibacterial Activity of Ethyl Acetate Extract of Medicinal Tree Species, Anacardium occidentale L. and Mangifera indica L.

This study was undertaken to evaluate the antioxidant property and antibacterial activity of ethyl acetate extract of mature leaves and flower of the medicinal tree species, Anacardium occidentale and Mangifera indica. 2, 2-diphenyl-1-picryl-hydrazyl radical (DPPH) free radical scavenging method and agar well diffusion method was used to detect antioxidant activity and antibacterial activity respectively. Various plant extracts of both the tree species studied were found to have potent antioxidant activity against DPPH and antibacterial activity against five human pathogens such as Pseudomonas aeruginosa; Salmonella typhi; Bacillus subtilis; Escherichia coli and Staphylococcus aureus. Therefore ethyl acetate extracts of mature leaf and flower extract of both A.occidentale and M.indica can be considered as a new potential source of natural antioxidants and antibacterial agent for pharmaceutical industries.
