“…However, GC of CPEFA methyl esters has not been successful; unlike other fatty acid methyl esters (FAMES), CPEFA methyl esters were reported to be thermally decomposed on the conventional polar columns (Recourt et al, 1967). In order to make CPEFAs heat stable for GC analysis, a second derivatization altering the cyclopropene moiety was sought through either hydrogenation (Cornelius et al, 1965;Bland et al, 1984;Conway et al, 1985) or reaction with methyl mercaptan (Raju and Reiser, 1966) or methanolic silver nitrate (Kircher, 1965; Authors Park and Rhee are with the Food Protein R & D Center, Faculty Mail Box 183, Texas A&M Univ., College Station, TX 77843-2476. Schneider et al, 1968).…”
