Abstract
In order to develop and make good use of Nitraria tangutorum Bobr. in Qinghai-Tibetan Plateau for its ecological and medicinal values, the seed oil was extracted by SFE-CO2 and the chemical constituents was analyzed by GC/MS. The component relative contents were determined by area nomalization. 28 components were separated from the extracts of SFE-CO2 and 12 of them, which accounted for 85.99 % were identified.They were ( Z, Z)-9, 12-octadecadienoic acid ( linoleic acid ), bicyclo [ 10. 1.0 ] tridec-1-ene, 7-pentadecyne,gamma-sitosterol, gamma-tocopherol, 1, E-8, Z-10-hexadecatriene, 9, 12-octadecadienal, 24-methyl-5-cholestene-3-ol, ( Z)-9,17-octadecadienal, stigmastan-3,5-dien, eicosane and so on. Among them, the relative content of (Z, Z)-9, 12-octadecadienoic acid is the highest, accounting for 65.85% of the total area. It is concluded that N. tangutorum Bobr. seed oil is a rich source of linoleic acid.关键词
