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.
