摘要：Two species of prickly pear from Morocco, Opuntia ficus indica (OFI) and Opuntia dillenii (OD) were investigated for fatty acids, sterols and vitamin E composition of the seed oil. Oils are obtained by hexane maceration under ambient temperature and analyzed by GC-MS. The main fatty acids of (OFI) and (OD) seed oil were respectively: linoleic acid: 58.79 and 79.83%, Palmitic acid: 11.18 and 13.52%. In both oils, stearic acid was present at low percentage: 1.50 and 2.75%. The content of unsaturated fatty acids was high, at 58.79% and 79.83% for (OFI) and (OD), respectively. The sterolic fraction was composed by β-sitosterol: 21.93 and 2.80%, campesterol: 3.75 and 0.51%, stigmasterol: 1.64 and 0% and fucosterol: 0 and 0.27% respectively. The sterol marker, β-sitosterol, accounted for 80.27% and 78.21% of the total sterol content in (OFI) and (OD) seed oils. In both oils, vitamin E, γ-tocopherol was present with low quantities 1.23% and 0.29% of total lipids respectively
