Analysis of burdock polysaccharide components by high performance anion exchange chromatography coupled with pulsed amperometric detection(牛蒡多糖组分的高效阴离子交换-脉冲安培分析)

应用高效阴离子交换色谱-脉冲安培检测器联用技术,研究了牛蒡多糖组分的检测方法和条件.以牛蒡为原料,采用水提醇沉法提取牛蒡粗多糖,并对其工艺进行探讨.牛蒡粗多糖经超声波酸水解处理后进行离子色谱分析,其最佳色谱条件为:以12 mmol • L-1 NaOH溶液为淋洗液,流动相流速为1. 0 mL • min-1,Carbo PaC PA10 (250 mm×4 mm i. d.)为分析柱,进样量25 µL.结果表明,牛蒡多糖中主要含有阿拉伯糖、果糖、葡萄糖和半乳糖,在优化的色谱条件下,各种单糖组分在一定浓度范围内线性关系良好,能很好地分离和准确测定.该方法操作简便、灵敏度高、重现性好....
