ABSTRACT

The current study investigated the phytochemical and antimicrobial characteristics of unsprouted mung bean seed obtained at Igasi Akoko, in Akoko North West Local Government Area of Ondo State, Nigeria. The seed (Vigna radiata L.) was grounded into powder and divided into two equal parts (A and B). Sample A was used as a positive control for bioactive components present in the seed. The crude extract of sample (B) was obtained by soaking in ethanol to extract the bioactive components. Qualitative and quantitative phytochemical analyses of samples (A) and extract of sample B were assessed. The phytochemical assay revealed that alkaloid, saponin, terpenoid, steroid, and cardiac glycosides were present, ranging from 12.47 to 47.25 mg/g and 8.05 to 27.73 mg/g respectively. The antimicrobial activity of the extract was tested against referenced microbial cultures using appropriate microbiological techniques. The antimicrobial activities of the extract vary with different zones of inhibition ranging from 2.85 to 3.10 mm against Salmonella typhi, ATCC6539 (3.05 mm) Pseudomonas aeruginosa ATCC9027 (3.10 mm) and Citrobacter freundi ATCC8090 (2.85mm) but Klebsiella pneumoniae, and Enterobacter aerogenes were resistant. The extract did not exhibit any antifungal effect against Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus. In light of this finding, mung bean seed could be considered as a potential source of natural antimicrobial agent.
