摘要：

本研究采用1-苯基-3-甲基-5-吡唑啉酮(PMP)作为还原醛糖的标记识别分子,利用高效液相色谱-紫外检测器(HPLC-UV)和普通C18色谱柱,建立了10种常见单糖在13.5min内的快速HPLC-UV分析鉴别技术,并成功地用于植物药水飞蓟多糖中单糖的组成分析。结果表明,醛糖的PMP标记与流动相三乙胺(TEA)配比分离调节相结合,可大幅度调节系列单糖PMP标记物的分离度,具有很高的分离可控性;水飞蓟多糖由甘露糖、鼠李糖、葡萄糖醛酸、半乳糖醛酸、葡萄糖、木糖、半乳糖及阿拉伯糖8种单糖组成,其摩尔比为0.66∶0.84∶0.58∶1.0∶1.6∶0.69∶2.7∶4.8;样品测定回收率为92.4%～104.0%。该方法简单、快速、准确,可用于水飞蓟多糖的有效质量控制。
