摘要 目的 建立高效液相色谱法(HPLC)测定浓缩苹果汁中棒曲霉素含量的方法。方法 浓缩苹果汁中棒曲霉素用乙酸乙酯提取,碳酸钠水溶液净化,蒸干乙酸乙酯层,其残留物用醋酸缓冲液溶解后。高效液相色谱法测定棒曲霉素的含量。采用Agilent1100 ODS(5μm,150mm×4.6mm i.d)色谱柱。流动相V(乙腈):V(水)=5:95。流速lmL/min,检测波长276nm。结果 棒曲霉素浓度在10μg/L--150μg/L范围内与峰面积有很好的线性关系:r=0.9990;棒曲霉素回收率:98%~103%,重现性好:RSD为1.8%;灵敏度高最小检出量为10μg/L。结论 用HPLC测定浓缩苹果汁中棒曲霉素的含量可操作性强、准确度高。
