The fatty acids contained in indigenous silkworm oil were determined by capillary gas chromatographyrmass spectrometry after their derivatization. Five different derivatization techniques were investigated using cold on-column and split injection systems. The separations were performed on three polar fused-silica capillary columns, coated with FFAP, Carbowax 20M, and SP-2340 stationary phases. The final results were resumed in a table. The indigenous silkworm oil is shown to contain 21แ23% palmitic acid, 0.2แ0.5% palmitoleic acid, 5แ7% stearic acid, 31แ34% oleic acid, 6แ8% linoleic acid, and 30แ32% linolenic acid. Traces of lauric, myristic, arachic, and behenic acids were also detected.
