Preliminary investigation on antioxidant interactions between bioactive components of Solanum anguivi and Capsicum annuum.

Evaluation of antioxidative interaction between two fruits of contra-similar characteristics belonging to same botanical family Solanacea namely S. anguivi and Capsicum annuum was accomplished in this study. The relative reducing power (RRP) and radical scavenging activity (RSA) of the mixture (11:0, 10:1, 5:1, 2:1, 1:1, 1:2, 1:5,1:10, 0:11) with antioxidant interaction range of 0.6958-2.4244 and 0.724-1.648 was obtained for RRP and RSA respectively for acetone-hexane derived extract. Similarly antioxidant interaction range from 1.045-1.486 to 1.0969-1.3166 was obtained for RRP and RSA respectively for ethanolic extract samples.This study demonstrated enhanced activity of S. anguivi and C. annuum when used as a mixture in comparison to when used alone. These results suggested that application of S. anguivi and C. annuum as mixture decreased intensity of undesirable sensory properties of high intensity bitterness and hot pungency associated with S. anguivi and C. annuum respectively without the use of taste masking agents.
