Abstract: Using the lemongrass (Cymbopogon citratus) which grown in Zhangzhou area, the essential oil is extracted to quantitatively inhibit Candida albicans in different forms, in order to screen the optimum form and the minimum concentration of this essential oil against C.albicans. In the study, the optimum form of inhibition were carried out by three forms of solid, gas and liquid, and the minimum concentration of the essential oil was tested. The qualitative experiment result showed that the essential oil of lemongrass had the best antimicrobial ability for C. albicans in solid state, and liquid state had the worst activity but was still significantly better than 5% fluconazole positive control (P<0.01). In the quantitative experiment, the minimum inhibitory concentration (MIC) of Candida albicans was 0. 15μL/mL in solid state. This experiment proved that the essential oil of lemongrass had the antimicrobial ability for Candida albicans in all three forms.
