目的 建立高效液相色谱法(HPLC)测定保健食品中盐酸氨基葡萄糖含量的简便方法.方法 样品用水超声提取,色谱柱:CAPCELL PAK CR(4.6 mm×150 mm,5 μm);流动相:25 mmol/L乙酸铵+乙腈(加0.1％甲酸)(25 +75,ⅣV);流量1.0 ml/min,检测波长200 nm.结果 盐酸氨基葡萄糖在0.2-26.0 μg范围内呈良好线性,相关系数为1.000;检出限为0.02 μg;回收率99.5％～101.0％;RSD 1.03％.结论 该方法操作简便快速、结果准确可靠,可作为保健食品中盐酸氨基葡萄糖的质量控制监测.
Objective To establish a method for the determination of glucosamine hydrochloride in health food by HPLC.Methods Samples were extracted ultrasonically with water and separated on a CAPCELLPAKCR column(4.6 mm×150 mm,5 μm);the mobile phase consisted of 25 mmol ammonium acetate+acetonitrile(in 0.1% formic acid)(25+75,V/V).The flow rate was 1.0 mL/min;the detection wavelength was 200 nm.Results The standard curve of glucosamine hydrochloride was linear over the range in 0.2~26.0 μg(r=0.999 982).The...
