ANTIOXIDANT POTENTIAL OF ENDOPHYTIC FUNGUS COLLETOTRICHUM SPECIES ISOLATED FROM POLYGALA ELONGATA
lessThan i greaterThan Colletotrichum lessThan /i greaterThan sp. was isolated as an endophyte of herbaceous plant lessThan i greaterThan Polygala elongata lessThan /i greaterThan collected from Western Ghats, India. In vitro evaluation of antioxidant property of ethyl acetate extract of this fungus was done using ABTS and DPPH radicals. The ethyl acetate extract of lessThan i greaterThan Colletotrichum lessThan /i greaterThan species lessThan i greaterThan lessThan /i greaterThan showed potent antioxidant activity against both ABTS and DPPH radicals with the IC lessThan sub greaterThan 50 lessThan /sub greaterThan value of 9.312μg/ml and 21.22μg/ml, respectively. Total amount of phenol and flavonoid quantified were of 1614mg/g gallic acid equivalents and 160mg/g of quercetin equivalent, respectively. In addition, total antioxidant capacity of the crude extract was evaluated by the phosphomolybdenum method and quantified as 23.695mg/g of Gallic acid equivalent. This study suggests that, the crude extract of lessThan i greaterThan Colletotrichum lessThan /i greaterThan sp lessThan i greaterThan . lessThan /i greaterThan may have potential source of natural antioxidant
