Bioactive Compounds, Antioxidant Activity, Minerals Composition and Antimicrobial Activity of Acacia nilotica Fruit Flesh and Seeds

Rayan A. Mohmmed and Elfadil E. Babiker

Abstract:
Background and Objective: Plant extracts can be used as alternatives for controlling food poisoning and preserving foods. Many studies have been carried out on Acacia nilotica fruit flesh, but the seeds have not been investigated. Therefore, a comparative study on bioactive compounds, antioxidant activity, minerals composition, fatty acid profile and antimicrobial activity of fruit flesh and seeds, was conducted. Materials and Methods: In the present study, bioactive compounds, antioxidant activity, minerals composition, fatty acid profile and antimicrobial activity were determined using standard methods and analyzed by using Student’s t-test. Results: The A. nilotica fruit flesh methanolic extract (ANFF) was rich in phenolic compounds compared to that of the seed (ANS). Phenolic compounds in ANFF significantly (p<0.01) higher than ANS. However, the antioxidant activity of ANS (92.63%) was significantly (p<0.05) higher than that of ANFF (89.88%). The fruit seed had significantly higher amounts of macro-minerals (p<0.05) and micro-minerals (p<0.01) than those in the fruit flesh. Linoleic acid in the seed and was significantly (p<0.01) higher than that of the flesh, but the flesh had significantly higher (p<0.05) oleic acid than that in the seeds. The ratio of unsaturated to saturated fatty acids exhibited considerable variation among the samples. SME significantly (p<0.05) inhibited the growth of Gram-negative (E. coli) and Gram-positive bacteria comparable to that of penicillin than do ANFF. Conclusion: The findings suggested that the flesh and seeds of A. nilotica are excellent sources of bioactive compounds, with the seeds having superior results.
