| 摘 要： | 为开发和利用白刺生态和药用的双重价值，运用气相色谱-质谱联用技术，分析研究青藏高原唐古特白刺超临界二氧化碳萃取种子油的化学成分。应用色谱面积归一法测定了各成分的相对百分含量。从检出的28个化合物中共鉴定了12种成分，占总量的85．99％。分别是(Z，Z)-9，12-十八碳二烯酸(亚油酸)，双环10．1．0]十三碳-1-烯，7-十五炔，γ-谷甾醇，γ-生育酚，1，E-8，Z-10-十六碳三烯，9，12-十八碳二烯醛，24-甲基-5-胆甾烯-3-醇，(Z)-9，17-十八碳二烯醛，豆甾烷-3，5-二烯，二十烷等。其中，(Z，Z)-9，12-十八碳二烯酸含量最高，占总量的65．85％。 |

| 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-CO 2 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-CO 2 and 12 of them,which accounted for 85.99% were identified.They were(Z,Z)-9,12-octadecadienoic acid(linoleic acid),bicyclotridec-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. |
