摘要: 采用双试剂柱后衍生法,在C18柱上以0.01mol/L 1-庚烷磺酸钠+乙腈为流动相及荧光检测器(Ex=263nm,Em=447nm)检测蜂蜜中链霉素的残留量,优化了蜂蜜样品的前处理方法和高效液相色谱条件,包括流动相组成和流速及衍生化试剂的处理,同时改善样品前处理过程中淋洗液和提取液的用量,并选用50%三氯乙酸作为沉淀剂,建立了一种更简便、快速、准确性和重现性好的链霉素检测方法。

Abstract: HPLC with post-column derivatisation was used to detect Streptomycin residues in honey, with 0.01mol/l sodium1-Heptanesulfonate and acetonitrile(65+35) as mobile phase and fluorescence detection (Ex=263nm,Em=447nm). Detectionconditions and parameters including the proportion and speed of mobile phase, arrangement of deriving agents, dosage of solutionand elution and usage of sedimentary agent were optimized. A new method with simplicity, repeatability and accuracy wasestablished in this paper.
