摘要(Abstract):

目的建立归脾丸中黄曲霉毒素G_2、G_1、B_2、B_1的残留量测定方法。方法样品经70%甲醇提取、免疫亲和柱净化后,用高效液相色谱-柱后光化学衍生-荧光检测器对归脾丸中4种黄曲霉毒素(G_2、G_1、B_2、B_1)的残留量进行分析测定。结果黄曲霉毒素G_2在1.232~24.64 pg范围内,黄曲霉毒素B_2在1.212~24.24 pg范围内,黄曲霉毒素G_1、B_1在4.148~82.96 pg范围内,线性关系良好,相关系数均r≥0.999 4。回收率在83.8%~101.4%之间。结论该方法快速简便、准确,可作为归脾丸中黄曲霉毒素残留量的测定方法。
OBJECTIVE To establish a method for the residual determination of aflaroxin G_2,G_1,B_2,B_1 in Guipi Pills.METHODS After being extracted by 70% methanol and purified by immunoaffinity columns,aflatoxins G_2,G_1,B_2,B_1 were analyzed by HPLC with post-column photochemistry derivatization and fluorescence detector. RESULTS Aflatoxin G_2 showed a good linear relationship at a range of 1.232-24.64 pg,and aflatoxin B_2 at a range of 1.212-24.24 pg,Aflatoxin G_1,B_1 at a range of 4.148-82.96 pg,r≥0.999 4. The recovery was between 83. 8%-101. 4%. CONCLUSION The method is simple,accurate and can be used to determine aflatoxins G_2,G_1,B_2,B_1 in Guipi Pills.
