双三元液相色谱—串联电喷雾检测器用于中药注射剂大分子物质筛查研究
张婷婷等
1 引 言
中药注射剂是在中医药制剂基础上发展起来的一种剂型,具有注射剂所共同的优点,并在一定程度保留了中医药的特色,在医疗实践中发挥了巨大作用。中药注射剂中可能存在的大分子化合物(如蛋白质、淀粉、鞣质、树脂等),这被认为是中药注射剂不良反应的主要因素之一[ 1]。检测和控制大分子物质已成为中药注射剂质量标准的重要指标,因此非常有必要建立灵敏、准确、简便的检测大分子物质的检测方法。
采用体积排阻除色谱法和示差折光检测器对中药注射剂大分子化合物进行分析,大大提高了测定结果的稳定性和灵敏度,但是与其它方法相比,示差检测器的灵敏度仍然不高。电喷雾检测器(Charged aerosol detector, CAD)作为一款通用型检测器。具有灵敏度高、响应一致性、重现性出色和检测范围宽的优势,因此具有广泛的实际应用范围[ 2,3]; 与紫外检测器相比,CAD能够很好地对无生色基团或弱紫外吸收的化合物进行测定,并且在同时检测多种最大吸收波长差异较大的物质时,CAD具有响应一致性优势[ 4]; 与示差折光检测器相比,CAD兼容梯度洗脱,大大提高了分离效率,并且灵敏度也显著提高[ 5]。本研究利用CAD的优势,采用HPLCCAD方法测定中药注射剂中的大分子化合物。

Abstract A size exclusion chromatography method (SEC) was established for the screening of macromolecules in traditional Chinese medicine (TCM) injections. In the experiment, TCM was collected through 0.45 μm hybrid filter and separated by SEC with MAbPac SEC1 column. Acetonitrile was added by postcolumn mode with a flow rate of 0.2 mL/min to enhance the detection sensitivity, and 25 mmol/L ammonium formate was used as the mobile phase at flow rate of 0.2 mL/min. The charged aerosol detection was carried out with Dextran and Tween as the reference standards. The molecular weight distribution of Dextran ranged from 2500 to 133800 had a good linear relationship with the retention time. No macromolecules were detected out in the selected traditional Chinese medicine injections except Kuhuang injections.
