| Abstract: | OBJECTIVE: Silkworm pupa oil was extracted by chemical method. Fatty acid in silkworm pupa oil was saponificated by KOH-MeOH and was modified to methyl esters by means of BF3-MeOH and was checked with thin-layer chromatography. Fatty acids were analyzed. METHOD: The compositions of fatty acids were determined by GC-MS and matched with NIST/EPA/NIH library. RESUTLS: Nine compositions in silkworm pupa oil were characterized and determined. The content of unsaturated fatty acids was 79.88%. The α-linolenic acid content in silkworm pupa oil was nearly 71.45% in its fatty acids. CONCLUSION: The α-linolenic acid may decrease plasma lipid and blood pressure, inhibit cancer. The study may be considered significant source for application of α-linolenic acid. |
