摘要
HPLC测定玉米中黄曲霉毒素B1,通过加标回收和精密度试验,对超声、振荡、高速均质3种样品前处理提取方法的提取效果进行了比较分析,结果表明:采用高速均质法处理样品,有较高的回收率和较好的稳定性.
During determination of AFT B1 in maize by HPLC, we analyzed and compared the extraction effect of three sample pretreatment methods （ultrasonic treatment, vibration treatment and high-speed homogenization） through standard recovery and precision test. The results showed that the sample treated by the high-speed homogenization method had higher recovery rate and better stability.
