Quantitative determination of cyclopropenoid fatty acids in cottonseed meal

Abstract: A rapid analytical procedure for determining the residual cyclopropenoid fatty acids (CPA) in cottonseed meal has been developed. The procedure involves room‐temperature extraction of crude CPA‐containing lipids with a hexane‐water‐acetone azeotrope solvent, followed by a benzenemethanol wash. The crude lipids are then converted to methyl esters by methanolysis with sodium methoxide. Extraction with petroleum ether, followed by washing with aqueous acetone, results in a substance which is free from interfering… Show more

“…The cyclopropenoid fatty acids, malvalic acid and sterculic acid, exist in hexane-defatted meal at levels of 21-76 ppm (70). In rainbow trout, the cyclopropenoid acids cause cancer of the liver either alone or by acting synergistically with aflatoxin B 1 .…”
