An analytical method for the determination of β-glycerophosphate and L-malate in glycerol phosphate preparations was established by ion chromatography with isocratic elution. α -Glycerol phosphate was completely separated from β-glycerol phosphate in the glycerol phosphate preparations. A Metrosep A Supp7 column (250 mm×4.0 mm, 5 μm) was used for separation with the eluent of 3.6 mmol/L Na₂CO₃ at a flow rate of 0.7 mL/min. The column temperature was 35℃. With this method, good accuracy and precision were obtained. The recoveries of the method ranged from 90.73% to 106.27%. The method is simple, rapid, sensitive, and suitable for the determination of β-glycerophosphate and L-malate in glycerol phosphate preparations.
