This study was conducted to analyses the antioxidant activity by using 2,2- Diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH) assay. There were five treatments that use in this study which are 0.1, 0.2, 0.4, 0.8 and 1.6 mg/ml extraction in each sample respectively. Significant differences (P ≤ 0.05) were observed in % inhibition of scavenging activity and IC₅₀. Methanol was used as an extracting solvent and ascorbic acid as a standard antioxidant. In this recent study, Daun Kesum (Persicaria odorata) was the highest sample that contribute to the highest antioxidant activities with IC50 and SD value is 64.28 and ± 0.058 respectively followed by Halia (85.47, ± 0.103), Samak Pedas (96.9, ± 0), Samak (113.64, ± 0.114), Bunga Kantan (121.65, ± 0.091), Jobeh (123.16, ± 0.011), Telang (478.54, ± 0.477) and Pitang (501.51, ± 0.800).
