Phytochemical screening, antioxidant activity and phenolic content of different plant parts of brucea javanica (L.) / Hidayatul Atiqah Abd Karim, Hamidah Jaafar Sidek and Zurina Mahmud
In this study, phytochemical screening, antioxidant activity as well as phenolic content in the leaves, twigs and barks of Brucea javanica (L.) were determined using standard phytochemical screening method, DPPH radical scavenging assay and Folin-Ciocalteu reagent method, respectively. Methanolic ex...
