Abstract
The present study was performed to evaluate the total flavonoids content, total phenolic content, total tannin content and antioxidant activities of the ethanolic extracts from Cnidoscolus aconitifolius fresh and dry leaves. The result showed that crude extract of Cnidoscolus aconitifolius fresh leaves had total flavonoids contents was 1.22 mg/ml, total phenolic content in crude extract of Cnidoscolus aconitifolius fresh leaves was 61.77 mg Gallic /g crude extract, total tannin content in crude extract of Cnidoscolus aconitifolius fresh leaves was 91.36 mg tannic /g crude extract. The highest antioxidant activity using DPPH free radical scavenging method was demonstrated by Cnidoscolus aconitifolius dry leaves at EC50 0.84 mg/mL
