Abstract :

The present study was aimed to compare chemical constituents and antioxidant activity in shade dried and sun dried methanolic peel extract of Punica granatum. The chemical constituents and % scavenging activity of shade dried and sun dried extracts was determined by standard qualitative tests and DPPH method, respectively. Shade dried and sun dried extract of P. granatum, standard exhibited highest free radical scavenging activity, i.e., 99.26%, 97.85 %, and 93.65% respectively at a concentration of 1000�g/ml. The findings showed that saponin was present only in shade dried peel extract of P. granatum. Rest of the chemical constituents was found to be present in both the extracts of P. granatum. However, determination of antioxidant activity of peel as well as other parts of P. granatum by other sensitive methods is warranted in order to explore full therapeutic potential of P. granatum peel.
