摘要:

建立了离子色谱等度洗脱检测甘油磷酸制剂中的 β-甘油磷酸根和L-苹果酸根的分析方法。实验采用Metrosep A Supp7离子色谱柱(250 mm×4.0 mm,5 μm)分离,3.6 mmol/L碳酸钠(Na2CO3)溶液等度洗脱,流速为0.7 mL/min,柱温为35℃,电导检测器测定,外标法定量。该方法可将甘油磷酸制剂中的 α -甘油磷酸根与 β-甘油磷酸根完全分离。β-甘油磷酸根和L-苹果酸根的加标回收率为90.73%~106.27%。该方法简单、快速、灵敏,适用于甘油磷酸制剂中 β-甘油磷酸根和L-苹果酸根的检测。

Abstract:

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.

Key words: β-glycerophosphate, glycerol phosphate preparations, ion chromatography (IC), L-malate
