LIPIDS OF ROEMERIA HYBRIDA SEEDS

The composition and content of fatty acids of oils obtained by Soxlet extraction (method 1) and ultrasonic extraction (method 2) from seeds of Roemeria hybrida growing in the Republic of Uzbekistan were studied by gas chromatography. As a result of the conducted studies, the presence of 12 unsaturated and saturated fatty acids was found in neutral lipids, and 15 in glycolipids and phospholipids. The content of unsaturated and saturated fatty acids in the oil obtained by method 1 is 87.90 and 12.10%, and in the oil obtained by method 2 – 87.84 and 12.16%, respectively. The main component of neutral lipids is linoleic acid, in the oil obtained by method 1, its content reaches 70.89%, and in the oil obtained by method 2 – 71.05%. The main saturated fatty acid of neutral lipids is palmitic acid, the content of which, depending on the type of extraction, is 9.64 and 9.57%. The content of polar lipids in seed oil was also determined, while during Soxlet extraction, polar lipids were obtained in greater quantities than during ultrasonic extraction. Glycolipids predominate in polar lipids. Glycolipids and phospholipids are characterized by saturated fatty acids, the main component of polar lipids is palmitic acid. Roemeria hybrida seed oil based on the analysis and fatty acid content close to Papaver somniferum seed oil.
