Parkia biglobosa plant seed husks and stem bark obtained in keffi, Nasarawa state, Nigeria, were screened for its phytochemicals, antimicrobial, toxicity and antioxidant characteristics. Carbohydrates, saponins, flavonoid, phtobatannin   were found present. The crude extract of seed husks has no inhibitory activity at minimum inhibitory concentration (MIC) of 2.0mg/cm3 on any of the micro-organisms but the bark has inhibitory activity on Candida albicans, Escherichia  coli, Bascillus Subtilis, and plasmodium species. The LC50 of 4.613 and 3.732 were found for the seed husk and bark respectively. The antioxidant characteristics measured as % Ascorbic acid were determined to be 80.54 and 90.70 for the seed husk and bark respectively. This does not compare favourably with a standard antioxidant, ascorbic acid (93.7%).

Key words: Phytochemical, antimicrobial, toxicity, antioxidant.
