| 520 | _aThe longan sample was extracted with 95% ethanol by ultrasonic-assisited method. The total optimum phenolic contents of longan peel with the help of ultrasonic method were 48.48mg/g at extraction temperature of 600C which was kept for 60minutes while the least values was observed at extraction temperature of 400C for 40minutes which is 24.48mg/g of the extract being expressed as gallic acid equivalent. The sample was measured at 760nm by using Folin-Ciocalteu method. The kinetic properties of antioxidants were investigated by reacting specific quantity of extract with 2.2-diphenyl-1-picrylhydrazyl (DPPH) radical and the reducing power was determined by mixing the longan extract with a number of different chemical species. The highest scavenging activity was shown by the sample extracted on 600C, 60minutes. The extraction temperature of 60C and 60minutes extraction time were found tobe the optimum for antioxidants extraction The antibacterial activity of longan extract was tested against E.Coliand strong activity was observed with distinct inhibition zones around the wells | ||
