Abstract

Samples of segregation 3 farmer stock peanuts from the 1980 southeastern United States growing season were analyzed for the presence of cyclopiazonic acid and aflatoxins. Cyclopiazonic acid appeared in 21 of 27 loose-shell kernel fractions at a range of 32 to 6,525 mug/kg and in 4 of 21 sound mature kernel fractions at a range of 32 to 130 mug/kg. Aflatoxins were detected in 26 of 27 loose-shell kernel fractions and in 20 of 21 sound mature kernel fractions. Cyclopiazonic acid used at 105 and 210 mug/kg to spike peanut samples was recovered at an average rate of 93.3%, with ranges of 89 to 119 and 166 to 221 mug/kg, respectively. The minimum detection limit on oxalic acid-impregnated silica gel plates was 26 ng.

摘要

对1980年美国东南部生长季的3类分离农户储备花生样本进行了环匹阿尼酸和黄曲霉毒素检测。在27份带壳花生仁样本中,有21份检测出环匹阿尼酸,含量在32至6525微克/千克之间;在21份健全成熟花生仁样本中,有4份检测出环匹阿尼酸,含量在32至130微克/千克之间。在27份带壳花生仁样本中有26份检测出黄曲霉毒素,在21份健全成熟花生仁样本中有20份检测出黄曲霉毒素。向花生样本中添加105微克/千克和210微克/千克的环匹阿尼酸后,其平均回收率为93.3%,含量范围分别为89至119微克/千克和166至221微克/千克。在草酸浸渍硅胶板上的最低检测限为26纳克。
