FRAP and phosphomolybdenum (PAP) antioxidant activities of the different plant extracts. Values are expressed as mean ± SD of three replicates. Values are expressed as mean ± SD of three replicates. In the same concentration the values affected with different letters (a–f) are significantly different at p < 0.05. FTE: P. guineense (stem) ethanolic extract; FTH: P. guineense (stem) hydroethanolic extract; FFE: P. guineense (leaves) ethanolic extract; FFH: P. guineense (leaves) hydroethanolic extract; BHT: butylated hydroxyl toluene.
