ANTIOXIDANT ACTIVITY OF LEAF AND FRUIT EXTRACTS OF RAUWOLFIA TETRAPHYLLA LINN.
AbstractFour crude extracts viz, methanol extract of fruit and n-hexane, dichloromethane, methanol extracts of the leaf of R. tetraphylla were investigated for in vitro antioxidant activity at different concentrations (5, 50 and 100 μg). Antioxidant ability is expressed as equivalents of ascorbic acid and was calculated using standard graph. The results indicated that the leaf n-hexane and methanol extracts was found to be significantly active at 5μg when compared with BHA, and at 50 μg concentration the methanol leaf extract found be very high. The fruit methanol extract was found to be active and the activity increased with increase in dose, but not as that of BHA. The experimental results show that the activity exhibited by the solvent extracts is dose dependent
