碳酸钙咀嚼片中辅料单糖醇的高效液相色谱-质谱分析

Analysis of Sugar Alcohol in Calcium Carbonate Tablets by HPLC-MS

用液相色谱-质谱联用法鉴定了进口碳酸钙咀嚼片中的辅料单糖醇为山梨糖醇,并对其含量进行测定;色谱柱为HypersilNH2(4.6×150mm,5μm),流动相为乙腈-水(体积比80∶20),质谱为检测器,以木糖醇为内标;山梨糖醇的线性范围为10.4～104mg／L,相关系数为0.9996,加标回收率在95%～98%之间;液质联用测定糖醇不需对样品衍生化,方法简便,检测灵敏度高。

A HPLC method for analysis of sugar alcohol in calcium carbonate tablets was described in this present paper.Sorbitol was separated on a Hypersil NH 2 (4.6×150mm ID,5μm)column with acetonitrile-water(80∶20)as mobile phase.The content of sorbitol in tablets was determinated.The linear responding range was from10.4to104mg/L(r=0.9996),and the mean recovery ranged from95%to98%.This newly developed method possesses the advantages of simple manipulation,no requirement of pretreatment of derivatization,high sensitivity.
