Effect of ethanolic extract of Omithogalum caudatum Ait on apoptosis of Candida albicans / 中国生化药物杂志

Objective To investigate the effect of Omithogalum caudatum Ait(OCA)on apoptosis of Candida albicans,illustrated the antifungal mechanism of OCA.Methods Annexin Ⅴ-FITC/PI double stainingwas used to detect the effect of OCA on the apoptosis of C.albicans;JC-1 and DCFH-DA staining were used to detectthe effect of OCA on mitochondrial membrane potential(MTP)and reactive oxygen species(ROS)of C.albicans.Results OCA had a good antifungal activity,the minimum inhibitory concentration(MIC)and the minimum fungicidal concentration(MFC)were 8mg/mL and 32mg/mL respectively.OCA could induceapoptosis of C.albicans,promote the reduction of MTP and increase of ROS.Conclusion OCA induced cell apoptosismainly through disrupting mitochondrial function.
