Rapid Procedure

Abstract A new method for the determination of aflatoxins in cottonseed is presented and compared with two other procedures. This procedure yields good recovery for added aflatoxin, is relatively simple and rapid, and produces relatively clean extracts for TLC. A 75 g sample of ground cottonseed or cottonseed meal is extracted with aqueous acetone, centrifuged to remove solids, treated with lead acetate and acetic acid to precipitate interfering substances, and recentrifuged. An aliquot of the supernatant is mixed with powdered cellulose and packed into a chromatographic column for liquid-liquid partition chromatography. Hexane elutes the lipid materials; the aflatoxins are eluted with a hexane-chloroform mixture. After solvent evaporation, the aflatoxin-containing residue is dissolved in chloroform and chromatographed by TLC. Silica gel is the adsorbent; a benzeneethanol-water mixture is the developing solvent. The aflatoxin content is estimated by comparison with standard aflatoxins.
