Determination of total phenolic contents and antioxidant activities in fruits of Solanum melongena L. (green) and Solanum melongena L. (purple)

Brinjol is one of most common vegetables consumed all around the world. The objective was to evaluate the total phenolic content and antioxidant activity in fruits of Solanum melongena L,(green)and Solanum melongena L, (purple)colored moderate size fruits. The study evaluated the total phenolic contents and antioxidant activity of extracts from purple colored and green fruit. The amount of total phenols, were analyzed using a colorimetric technique, based on Folin -ciocalteau reagent. Gallic acid was used as standard compound and the total phenols were expressed as mg equivalents. The in vitro antioxidant activity was done by 1,1diphenyl.2picryl hydrazyl (DPPH) free radical scavenging activity. The results demonstrated that green colored medium size fruit demonstrated the highest total phenolic content and antioxidant activity of 320ug/500ul of the sample. The results of this study would provide an understanding of the total phenol content of the two vegetables and its antioxidant activity. The maxi mum phenolic content was found Solanum melongena L. (green).
