Abstract:

Soxhlet extraction was used to extract seed oils from 10 plant samples (from different areas of China) belonging to 5 varieties of the genus Perilla, followed by the fatty acid composition analysis using GC-MS. The oil contents of these 10 Perilla seed samples ranged from 33.49% to 42.58%. The one-way analysis of variance achieved using software package SPSS 11.0 showed that there was a significant difference in oil content among these 10 Perilla seed samples. The GC-MS analysis indicated that these 10 Perilla seed samples exhibited simple fatty acid composition. Palmitic acid, linoleic acid, α-linolenic acid and stearic acid were found in all of these 10 Perilla seed samples. Oleic acid was found only in Perilla seed samples No. 1, 2, 3 and 5 and 10-octadecenoic acid only in Perilla seed samples No.4 and 6-10. The relative contents of α-linotenic acid of these 10 Perilla seed samples ranged from 71.75% to 80.06% and the content of unsaturated fatty acids from 88.80% to 92.82%.
