Free radical scavenging activity of the leaves crude extracts of J. excels were tested using DPPH method and the results are presented in Figure 1. The antioxidant is depends on their interaction with oxidative free radicals.The assumption of DPPH method is that the antioxidants react with the stable free radical and gradually discolouration. The degree of discolouration indicates the scavenging potentials of the samples.In this study, the four organic extracts from J. excels were capable to decolourise DPPH.
