Study on the extraction and antibacterial activity of Monascin

Taking monascin as the research object, was extracted from red kojic rice by ethanol extraction and with 60%, 70% 80% respectively. Finally, it concluded that when concentration of 70%, rate highest, reached 75.68%. The bacteriostatic experiments extract fermentation showed had strong inhibitory effect on Staphylococcus aureus Bacillus subtilis , weak ability Escherichia coli Aspergillus niger no obvious growth Saccharomyces cerevisiae .
