چکیده
Accepted: 08/06/2014 Abstract Six variety of betel leaf from different domain of India were extracted using five solvents in order to determine the effect of solvent and changing variety on total phenol content and antioxidant activity. Antioxidant activity was determined using DPPH, ABTS, FRAP, PCL (Photochemluminiscence) assay. However 80% methanol for TPC, 80% ethanol followed by 80% methanol for DPPH and 80% ethyl acetate for all other antioxidant assays proved to be the convenient extraction medium. Variety wise TPC of Desi bagla, DPPH of Sofia, ABTS and FRAP values of Banarasi safeda and PCL value of Calcutta were found to be more efficient. Weak to strong relationship were observed in different extracts of each solvent with highest r value of 0.95 (p<0.001) between TPC and ABTS. Wide range of correlation coefficient was derived within four different antioxidant assays of each betel leaf extracts with consistently high relationship observed between TPC and FRAP values.
