Abstract:
Object To establish a method by high performance liquid chromatography/evaporative light scattering detector (HPLC-ELSD) for the determination of contents of D-fructose, D-glucose, and sucrose in Siwu Decoction (SWD). Methods Condensed SWD was analyzed by HPLC-ELSD after dilution, precipitation by ethanol. Results Condensed SWD, 1 mL, contained (33.4?1.5) mg of D-fructose, (24.2?0.9) mg of D-glucose and (112.7?6.1) mg of sucrose. The standard curves were linear within the range of 0.15—3.75 mg/mL for D-fructose and 0.15—5 mg/mL for D-glucose and sucrose. The recovery rates were 128.5% for D-fructose, 114.7% for D-glucose, and 124.7% for sucrose. The relative standard deviations (RSD) within-days were 3.0% for D-fructose, 3.2% for D-glucose, and 4.4% for sucrose. Conclusion SWD contains abundant monosaccharide and disaccharide. HPLC-ELSD can be used to analyse the monosaccharide and disaccharide in SWD.
