Aktivitas Antioksidan Ekstrak Etanol Daun Sungkai (Peronema canescens Jack)

Abstract

Sungkai plants (Peronema canescens Jack) are found in the Central Bengkulu region. Sungkai leaves contain alkaloids, flavonoids, phenolics, and saponins that act as natural antioxidants. The antioxidant activity of old and young sungkai leaves was analyzed using the DPPH method. Sungkai leaves are known to contain antioxidant activity, which is indicated by the change in DPPH color from purple to clear yellow. The results showed strong antioxidant activity with IC50 values (inhibitor concentration 50) of 50.838ppm for young sungkai leaves and 52.835ppm for old sungkai leaves.
