Abstract:

Kalimeris indica seed oil was extracted by Soxhlet extraction from Kalimeris indica seeds with two different granule sizes. Fatty acids in Kalimeris indica oil were esterified and analyzed by gas chromatography-mass spectrometry (GC-MS). Components and relative contents of fatty acids were compared. Results indicated that 16 fatty acids were identified in Kalimeris indica seeds with granule size larger than 1 mm and 14 fatty acids were identified in Kalimeris indica seeds with granule size less than 1 mm. Contents of total fatty acids were 98.66% and 96.84% in both kinds of Kalimeris indica seed oil, respectively. The major fatty acids in Kalimeris indica seeds were octadecadienoic acid, octadecenoic acid and hexadecanoic acid.
