Abstract:

The phytochemical screening of the plants extracts revealed some differences in the phytochemical constituents of the plants tested. All the plants except Strophanthus hispidus leaves extract tested positive for flavonoids. Only Cassia alata root extract, Ficus saussureana leaves extract and Moringa oleifera leaves extract tested positive for Phlobatonin. Saponin was found in all the plants extract in Moringa oleifera root and Strophanthus hisidus root extracts. It was found that terpenoids were present in all the plants extracts except Strophanthus hispidus (leaves and root) and Ficus saussur

Abstract Reactive oxygen species causes harm to cell membranes and biomolecules, wherefore chronic diseases develop. Antioxidants scavenge such free radicals combating oxidative stress. This research aimed to determine the antioxidant potential of the aqueous stem bark, root and leaf extracts of Rhaphiolepis bibas against standards. DPPH radical scavenging activity was high from th stem bark extract at 72.33% with root extract at 65.85% and leaf extract at 55.91%, while ascorbic acid scavenged 89.53% of DPPH radicals. The leaf extract had the highest H2O2 scavenging activity of 91.92% with ste
