Abstract: Some selected medicinal plants used by Myanmar people were evaluated for potential antioxidant and antimicrobial properties. In this study, the antioxidant activity of 14 types of medicinal plants collected from Kyaukse origin of Mandalay Division in the country Myanmar was estimated using1, 1-diphenyl-2-picryl-hydrazyl (DPPH), ferric reducing antioxidant power (FRAP) assay and total phenol content assay. The highest antioxidant activity was demonstrated by Vitis vinifer Linn. Phyllanthus urinaria and Zingiber officinale in all tested in vitro antioxidant assays. As far as antimicrobial activity is concerned, ethanolic extracts of Vitis vinifer Linn, Sida acuta, Phyllanthus urinaria, Z. officinale Calendula officinalis Caccinia Indica and Curcuma Longa were found to be most potent against clinically important bacteria Bacillus cereus, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans and Enterococcus faecalis. Brine shrimp lethality test was also conducted to examine the toxicity of selected plant extracts. The experimental results suggest that all the tested plant extracts are non-toxic and no potential health risk for human consumption.
