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。
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 ad- vantages.
