The BF and Pons’ methods gave better efficiency than the other two methods. Spectrophotometric method was more effective than TLC and minicolumn techniques. BF method was found relatively less expensive and less time consuming as compared to other extraction methods. The Pons’ method was found convenient while handling large numbers of samples especially in the absence of centrifuge facilities required for the BF method. %T Comparison of different methods for extraction and estimation of aflatoxin B1 in groundnut
