Evaluation of natural pigments as antioxidant and antibacterial agents from tagetes erecta flowers extracts

Abstract

The present work is designed to evaluate the antioxidant, antibacterial activity and (TPC) total phenolic content of Tagetes erecta flowers extracts. Antioxidant potential of flowers extracts was examined by applying three different methods. Antibacterial test was determined against gram positive and gram negative bacterium. The ethyl acetate extract had the greater phenolic concentration of 48.2 mg/g GAE followed by methanol extract which was 42.5 mg/g GAE and hexane extract 36.4 mg/g GAE. The ethyl acetate extract was found to be most effective in all the antioxidant methods in correlation with the TPC value. Moreover, all the flowers extracts are significantly effective in both Gram negative and Gram positive bacterium. Tagetes erecta flowers are hopefully considered as a promising source of natural pigments with a scope towards the alternative therapy for treatment of various health problems.
