Résumé
Lipids are major chemical components of plants and animals. The prickly pear cactus genus Opuntia (family Cactaceae) is a widely distributed plant growing in arid and semi-arid areas. Lipid and fatty acid composition of prickly pear cactus was investigated using GC-MS chromatography. Fatty acid profiles of seed, mesocarp and exocarp of cactus pear were analyzed, as well as from cactus cladode parenchyma. Total amounts of saturated, monounsaturated and polyunsaturated fatty acids were identified. The most abundant fatty acids were 18:2 > 18:1 > 16:0 > 18:0 in seed and 16:0 > 18:1 > 22:0 >20:0 in exocarp. Fatty acids 18:1 and 16:0 were found in fruit mesocarp while parenchyma had only 16:0. Triglycerides were the only lipid subclass seen in seeds, shown by thin-layer chromatography (TLC) results. The information provided in this study will be important for further chemical and nutritional investigation of prickly pear cactus.
