TL;DR: A thin layer chromatographic system including densitometry has been developed for determining cyclopiazonic acid in peanuts and corn using methanol-chloroform and derivatization with dimethylaminobenzaldehyde-HCl spray.
Abstract: A thin layer chromatographic system including densitometry has been developed for determining cyclopiazonic acid in peanuts and corn. Samples are extracted with methanol-chloroform (20 + 80); the extract is stripped of most interferences by partitioning with aqueous sodium bicarbonate followed by acidification and repartitioning with chloroform. After thin layer chromatography and derivatization with dimethylaminobenzaldehyde-HCl spray, the toxin is quantitated by reflection densitometry at 540 nm. The recovery of cyclopiazonic acid averages 90% for peanuts and 85% for corn. The absolute detection limit is 25 ng per spot which translates to a detection limit of 125 micrograms/kg for a 50 g sample.
