Abstract

Antioxidant properties of five Aristolochiaceae species namely Aristolochia brasiliensis Mart. and Zucc., Aristolochia bracteolata Retz., Aristolochia indica Linn., Apama siliquosa Lamk. and Aristolochia
tagala Cham. were investigated. Antioxidant and 2,2-diphenyl picrylhydrazyl (DPPH) radical scavenging activities, reducing powers, and the amount of total phenolic compounds of the extracts were studied.
The highest antioxidant activity was shown by A. tagala and the lowest one was A. brasiliensis. The highest DPPH radical scavenging activity was shown by A. tagala and the least one was shown by A. brasiliensis. The highest reducing power and amount of total phenolic compounds was shown by A. tagala and lowest one was A. brasiliensis.
