Abstract

A new IS-anionic stationary phase was synthesized to make on-line extraction of the ochratoxin A and B from samples of beer for HPLC. The propyltriethylammonium chloride stationary phase was characterized affecting it's elementary determination and RI specter, respectively. Evaluation of the IS-anionic column for the extraction and quantification of OTA and OTB in beer has shown that the column is suitable for efficient extraction (recovery >76.5%) and precise analysis. The detection limits for OTA and OTB were 0.03 and 0.07 mugL(-1), respectively. The range of detector linearity was 0.03 at 20 mugL(-1).

摘要

合成了一种新型的离子对固定相，用于从啤酒样品中在线萃取赭曲霉毒素A和B，以进行高效液相色谱分析。分别通过元素测定和折光指数光谱对丙基三乙氯化铵固定相进行了表征。对该离子对固定相用于啤酒中OTA和OTB的萃取和定量分析的评估表明，该柱适用于高效萃取（回收率>76.5%）和精确分析。OTA和OTB的检测限分别为0.03和0.07 μg/L(-1)。检测器线性范围为0.03至20 μg/L(-1)。
