Abstract

Fatty acids were extracted from seed melon seed by Soxhlet extraction and 10 fatty acids were isolated and identified by gas chromatography-mass spectrometry (GC-MS). Linoleic acid, hexadecanoic acid and octadecanoic acid were the major fatty acids, accounting for more than 89.01% of total fatty acids. Volatile oil obtained by simultaneous distillation extraction method from seed melon seed was analyzed by GC and GC-MS. A total of 30 compounds were identified and alkane (22.44%), alcohol (17.22%), organic acids (12.86%) and ketone 2.36%) were the major components representing more than 60.55% of the oil.
