Abstract

Introduction: Muscari neglectum has been used as food in some countries. Objective: The antimicrobial and antioxidant activities of M. neglectum were the subject of the study. Methods: In this study, the total phenolic, flavonoid, monomeric anthocyanin contents, antioxidant and antimicrobial activity of M. neglectum flowers ethanol extract were determined by different methods against some food poisoning microorganisms. Results: Total phenolic, flavonoids and anthocyanin contents of the extract were 18.2, 0.94 and 0.11%, respectively. The IC50 for M. neglectum was higher than that of BHT. M. neglectum extract showed no inhibition zone (IZ) against Staphylococcus aureus and had small IZ against Candida albicans and Aspergillus niger. Shigella flexneri and Escherichia coli had the higher IZ than the others. The lower MIC and MLC values were for C. albicans, followed by Sh. flexneri and E. coli. S. aureus had the higher MIC and MLC values than the others. Conclusion: Therefore, the M. neglectum flower extract can be used as a natural preservative and coloring agent in foods as replacement of synthetic ones.
