    Abstract This paper describes a GC method to measure simultaneously fructose and glucose content in Da Mi Wan. Before GC determination, samples were derivatized with hexamethyldisilazane (HMDS) and trimethylchorosilane (TMCS) (2∶1).The calibration curves were linear between 0.3097 mg and 2.1680 mg for fructose, with r=09997 and the RSD of 1.42%, and between 0.2156 mg and 1.5093 mg for glucose, with r=0.9995 and the RSD of 1.20% respectively.
