C. Doneanu et al., CAPILLARY GC MS CHARACTERIZATION OF FATTY-ACIDS FROM INDIGENOUS SILKWORM OIL/, The Journal of microcolumn separations, 9(1), 1997, pp. 37-41
The fatty acids contained in indigenous silkworm oil were determined b
y capillary gas chromatography/mass spectrometry after their derivatiz
ation. Five different derivatization techniques were investigated usin
g cold on-column and split injection systems. The separations were per
formed 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 21
-23% palmitic acid, 0.2-0.5% palmitoleic acid, 5-7% stearic acid, 31-3
4% oleic acid, 6-8% linoleic acid, and 30-32% linolenic acid. Traces o
f lauric, myristic, arachic, and behenic acids were also detected. (C)
