| 中文摘要: |
| 采用索氏提取法和GC-MS法测定并分析了6个不同产地亚麻籽含油率及亚麻籽油脂肪酸组成。结果表明：不同产地亚麻籽含油率在36.59%~44.88%之间，含油率与产地的生长季积温呈显著负相关（r=-0.839 5，P=0.036 6）；亚麻籽油中相对含量最高的5种脂肪酸分别是亚麻酸（53.36%~65.84%）、亚油酸（10.14%~16.39%）、油酸（10.03%~12.37%）、硬脂酸（3.98%~9.85%）和软脂酸（2.41%~7.97%），不饱和脂肪酸含量高达77.51%~92.39%。综合含油率及不饱和脂肪酸相对含量等因素，最终确定甘肃陇南作为优质亚麻籽油生产地具有一定优势。 |
| 英文摘要: |
| Oil contents in flaxseed from six different origins and fatty acid compositions of flaxseed oils were measured and analyzed by Soxhlet extraction and GS-MS. The results showed that the oil contents of flaxseeds from different origins ranged from 36.59% to 44.88%.The oil contents were significantly and negatively correlated with accumulated growing season temperatures （r=-0.839 5, P=0.036 6）. Fatty acids of flaxseed oils were mainly composed of linolenic acid （53.36%-65.84%）, linoleic acid （10.14%-16.39%）, oleic acid （10.03%-12.37%）, stearic acid （3.98%-9.85%） and palmitic acid （2.41%-7.97%）. The unsaturated fatty acids contents were up to 77.51%-92.39%. Based on oil contents and unsaturated fatty acid contents, flaxseed oil from Longnan district exhibited obvious advantages. |
