Abstract

The extracting conditions and anti-microbial activity of essential oil in Fenugreek were studied.The results showed that the optimum extraction conditions were soaking time for 20min,ratio to solvent 1∶4(g∶mL),extracting time for 20min and ultrasonic power 50 W.Under this extracting conditions,the yield of essential oil is to 2.61%.Essential oil in Fenugreek had strong anti-microbial activity,and the Minimum Inhibitory Concentration(MIC)of the essential oil was 0.4g/L against Bacillus subtilis,1.0 g/L against Aspegillus niger,0.6 g/L against Actinomucor sp.,and 0.5 g/L against E.coli.,S.aureus,Penicillium sp.

Key words： Fenugreek; essential oil; ultrasound wave; extraction conditions; anti-microbial activity
