Study on Antimicrobial Activities of Persimmon Leaves and Isolation and Elucidation of the Activity Compounds

Abstract

Abstract: Antimicrobial activities of persim mon leaves against seven food spoila ge and food -borne pathogens have been tested for the first time.T he results showed that the MIC(minimun inhibition concentrations)and the MBC(minimum bactericidal concentratio ns)of persimmon leaves were determined as 0.313and0.625g /ml against tested food spoilage and food -borne pathogens respectively,and that their antimicrobia l rate was more than 90%.The activity c ompounds in persimmon leaves have been isolated and elucidated as volatile oil,total flavonoid,coum arins,and organic acid.

Key words: persimmon leaves, antimicrobial activity, isolation and elucidation, food spoilage and food -borne pathogens
