This study deals with the phytochemical analyses, antioxidant and antimicrobial activities screening of Erodium glaucophyllum root bark. Organic extracts (Chloroformic Acid and Ethyl acetate) were screened for their biochemical composition as well as antioxidant and antibacterial activities. Phytochemical screening of Erodium glaucophyllum root bark showed the presence of flavonoids, coumarins, saponins, tannins, antracenosides, phenolics compounds and mucilage. Biochemical screening of the two organic extracts show a highest total polyphenolic content of the two solvent (78.022 ± 0.28 mg GAE/g DM in Chloroform extract and 95.468 ± 0.078 mg GAE/g methyl acetate extract). These values were recorded in the proportion of 70% MeOH. The antioxidant activity was evaluated using DPPH tests, chelation, and the total antioxidant capacity. The antibacterial activity was evaluated by the diffusion test agar vis-a-vis of six bacterial strains. The results show that the levels of polyphenolic content influenced these activities.
