Objective:To investigate phytochemical screening,antimicrobial activity and qualitative thin layer chromatographic separation of flavonoid components,antioxidant activity and total flavonoid compound of Terminalia ***:For phytochemical screening,some common and available standard tests were *** bioassay was done through agar well diffusion *** of antioxidant activity and flavonoid compounds were done through thin layer *** antioxidant activity was measured by 2,2-diphenyl-1-picrylhydrazyl(DPPH)in colorimetric *** chloride colorimetric method was used for total flavonoid ***:Phytochemical screening showed the active compounds presence in high concentration,such as phytosterol,lactones,flavonoids,phenolic compounds and tannins and *** anlimicrobial activity of extract showed that greater inhibition zone against Gram negative bacteria than Gram positive *** methanolic extract showed a promising antioxidant activity,as absorption of DPPH redicles decreased in DPPH free radical scavenging *** components having antioxidant property present in the methanol extract at a level of199.00 mg quercetin equivalent/g of dried methanol extract in colorimetric ***:The Terminalia arjuna bark extract revealed the presence of bio-active constituents which are known to exhibit medicinal as well as physiological activities.
