Abstract: The antioxidant activity of fresh and dried plant extracts of Paederia foetida and Syzygium aqueum were studied using β-carotene bleaching and the 2,2’-azinobis(3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) radical cation assay. The percentage of antioxidant activity for all extract samples using both assays was between 58 and 80%. The fresh samples of both plants had higher antioxidant activity than the dried samples. The results of the β-carotene bleaching assay were correlated (R2 = 0.9849) with those of the ABTS assay.
