摘要
目的 建立免疫亲和柱净化柱后光化学衍生高效液相色谱-荧光检测法同时测定人参归脾丸中黄曲霉毒素(aflatoxi, AF)B、B、G、G的含量。方法 样品采用70%甲醇作为提取溶剂,经免疫亲和柱净化、高效液相色谱分离、光化学柱后衍生后,通过荧光检测器测定其中AF的含量。结果 AFB的线性范围为0.010 4~0.052 0 ng(r=0.999 9)、AFB的线性范围为0.003 8~0.019 0 ng(r=0.999 8)、AFG的线性范围为0.010 8~0.054 0 ng(r=0.999 8)、AFG的线性范围为0.003 8~0.019 0 ng(r=0.999 8),均线性关系良好,回收率在89.68~101.44%之间,RSD≤3.5%。结论 该方法操作简便,灵敏度高、重复性好、结果准确,可用于人参归脾丸中AF的测定。
Objective This paper aims to establish the contamination method of AFB,B,Gand Gin Ginseng spleen-invigorating bolus by immunoaffinity column clean-up and HPLC-FLD with post-column photochemical derivatization.Methods After extraction with 70% Methanol and purification by immunoaffinity columns, AFB,B,Gand Gin samples were analyzed by HPLC-FLD with post-column photochemical derivatization.Results The linearity of AFBwas at 0.010 4-0.052 0 ng(r=0.999 9), AFBwas at 0.003 8-0.019 0 ng(r=0.999 8), AFGwas at 0.010 8-0.054 0 ng(r=0.999 8), AFGwas at 0.003 8-0.019 0 ng(r=0.999 8). The average recoveries were within 89.68-101.44%, with RSD≤3.5%.Conclusion The above method has demonstrated convenient operation, good repeatability, highsensitity and accuracy.This method is suitable for the determination of AF in Ginseng spleen-invigorating bolus.
