摘要: 建立用示差折光高效液相色谱法测定复方胃蛋白酶颗粒中葡萄糖、蔗糖、麦芽糖含量的方法。选用色谱柱为Sugar-D,流动相为乙腈-水(78:22,V/V),流速为1.0mL/min,在室温条件下进样分析。结果表明:在该条件下,葡萄糖、蔗糖、麦芽糖能够较好分离,在 0.50~10.00mg/mL范围内线性关系良好;葡萄糖回收率为94.3%~103.7%,蔗糖回收率为101.4%~105.1%;经不确定度评价,合成不确定度为1.92%,扩展不确定度为4.1%。该方法简单、准确、稳定、可靠,可用于复方胃蛋白酶颗粒中葡萄糖、蔗糖的含量测定。

Abstract: A high performance liquid chromatography with refractive index detection (HPLC-RI) method was established for the simultaneous quantification of glucose, sucrose and maltose. The chromatographic separation was achieved on a Sugar-D column using a mixture of acetonitrile and water (V/V=78:22) as mobile phase at a flow rate of 1.0 mL/min. Under these conditions, glucose, sucrose and maltose could be well separated. A good linear relationship for each analyte was observed over the concentration range of 0.50-10.00 mg/mL. The spike recoveries of glucose and sucrose were 94.3%-103.7% and 101.4%-105.1% respectively. The results of uncertainty evaluation indicated that the combined standard uncertainty was 1.92% and the expanded uncertainty was 4.1%. The method was simple, accurate, stable, reproducible, and suitable for the practical determination of glucose, sucrose and maltose in compound saccharated pepsin granules.
