| 中文摘要: |
| 分析了3个产地44个文冠果油的脂肪酸和甘油三酯组成。从文冠果油中共分析出12种脂肪酸，含量较高的分别是亚油酸(40.89%~43.20%)、油酸(29.63%~31.66%)和芥酸(8.29%~8.45%)。文冠果油不饱和脂肪酸占90%以上，单不饱和脂肪酸和多不饱和脂肪酸的比例在1.08~1.20 之间。采用HPLC-TOF/MS共鉴定出33种可能的甘油三酯，构成这些甘油三酯的脂肪酸包括棕榈酸、硬脂酸、油酸、亚油酸、花生酸、花生一烯酸、山嵛酸、芥酸、木焦油酸以及二十四碳一烯酸等。文冠果油含量较高的甘油三酯为OLL(18.02%～2015%)，其次是OOL(8.08%～8.42%)和LLAo(7.75%～8.20%)。同时，对不同产地文冠果油脂肪酸和甘油三酯含量的相关性进行了分析研究。为文冠果油品质研究及掺伪鉴别提供数据支撑。 |
| 英文摘要: |
| The compositions of fatty acid and triglycerides of 44 samples of Xanthoceras sorbifolia Bunge. oil from three producing areas were analyzed. Twelve kinds of fatty acids in Xanthoceras sorbifolia Bunge. oil were identified, and the contents of linoleic acid(40.89%-43.20%), oleic acid(29.63%-3166%) and erucic acid(8.29%-8.45%) were higher. The content of unsaturated fatty acids in Xanthoceras sorbifolia Bunge. oil was above 90%, and the ratio of monounsaturated fatty acid to polyunsaturated fatty acid was 1.08-1.20. 33 kinds of triglycerides in Xanthoceras sorbifolia Bunge. oil were identified. The triglycerides were formed from palmitic acid, stearic acid, oleic acid, linoleic acid, arachidic acid, arachidonic acid, docosanoic acid, erucic acid, lignoceric acid and nervonic acid. The content of triglyceride OLL (18.02%-20.15%) in Xanthoceras sorbifolia Bunge. oil was the highest, followed by OOL(8.08%-8.42%) and LLAo(7.75%-8.20%). Meanwhile, the correlation analysis between the contents of fatty acid and triglyceride in Xanthoceras sorbifolia Bunge. oil was carried on. The results could provide data support for the quality study and adulteration identification of Xanthoceras sorbifolia Bunge. oil. |
