Antioxidant activities of the crude ethanolic and essential oils extracts of baobab plant, Adansonia digitata was determined using standard methods. Extracts of the fresh leaves were obtained using modified steam distillation. The antioxidant activities of the essential oils was screened using DPPH method in comparison to ascorbic acid as standard and the IC50 values for the plant's crude ethanolic extracts was found to be 0.5590 in Adansonia digitata, and 0.4281 for ascorbic acid; while the IC50 values obtained for essential oil was 0.4280 for ascorbic acid and absent in Adansonia digitata. Adansonia digitata was analysed by GC-MS, and 5 compounds from it were obtained and identified. They were 1,5-diamino-2-ethyl-1,2-dihydro-3H-pyrole-3,3,4-tricarbonitrile (37.14%), Phenylaniline (54.95%), Isopropenyl-4,5-dimethyloctahydroindene-4-carboxylic acid (3.26%), Octadecanoic acid (2.91%) and Phenyl-4-(1H-tetrazol-4,5-ylcarbamoyl)-butyric acid (1.75%). The results, thus support the traditional use of the plants to treat chronic diarrhoea, fever, diabetes, kidney stone, asthma, general fatigue, digestive disorder, respiratory infection and insect bites. Hence, suggesting its usage in the formulation of new antioxidant and antibacterial drugs and its credence as food.
