dc.description.abstract Anise (Pimpinella anisum, Apiaceae) is an annual herbaceous plant used traditionally in folk medicine in Sudan. The objectives of this work were to identify the composition of oil extract of anise seed, and study its antimicrobial and antioxidant activity. Anise seeds were collected randomly from El-Obeid local market. Using gas chromatography/mass spectrometry 29 compounds including Anesole, Enisole P.allyl, Limonone, Mionene and Palmicinic acid were identified in the extracted oil. The diffusion method was used for assessing the antimicrobial activity using five different concentrations of the oil (10%, 5%, 2.5%, 1.25%, 0.63% ) against four bacteria species (Staphylococcus aurous, Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli) and two fungi species (Candida albican and Aspergillus niger). The results showed that 10% concentration exhibited the highest activity against P. aeruginos with inhibition zone diameter of 20.22 mm. The 5%, 2.5%, 1.25% concentrations showed a comparable activity against E. coli and B. subtilis with inhibition zone diameter in the range of 17 to 18mm. The concentration 0.63 % showed weak activity against all the tested microorganisms except against P. aeruginosa that showed an inhibition zone of 17 mm diameter. The inhibition zone of C. albican was higher than that of A. niger. The antioxidant activity of the extracted oil was evaluated using the standard 2,2 diphenyl - 1 - picrylhydrazyl (DPPH) 0.5 ml. The antioxidant activity of the extracted oil was 22.84±1.0. en_US
