Abstract:

Kalimeris indica seed oi1 was extracted by Soxhlet extraction. The fatty acids in Kalimeris indica seed oil were esterified by two methods and analyzed by gas chromatography-mass spectrometry (GC-MS).The components and relative contents of the fatty acids esterified by two methods were compared. The results showed that 16 fatty acids were identified by the first esterification method and 6 fatty acids were identified by Esterification Method 2. The contents of the identified fatty acids accounted for 98.66% and 63.68% of Kalimeris indica seed oil, respectively. The predominant fatty acids of Kalimeris indica seed oil were octadecadienoic acid, octadecenoic acid and Hexadecanoic acid by two esterification methods.

Key words: Kalimeris indica seed, atty acid, soxhlet extraction, esterification method, gas chromatography-mass spectrometry(GC-MS)
