Abstract: Objective To establish a high performance liquid chromatography-mass spectrum(HPLC-MS) method to determine trehalose in the biofilm of Candida albicans. Methods Shisheido CAPCELL NH2(150 mm×4.6 mm,5 μm) was used in this method and the mobile phase is 75% acetonitrile and 25% pure water.MS detector with an ESI ion source in negative mode was used. Results It has a good separation of trehalose and internal standard,and there is no interference of endogenous impurity.Linear was from 0.05~50 μg/ml(r=0.999 3),recovery was in the range of 81.50% to 96.29% and the RSD of precision is less than 2.1 %. Conclusion This method is a simple method for quantification of trehalose in fungus.
