ABSTRACT
Objective:
To analyse the composition and content of the fatty acid and unsaponifiable matters in both tartary buckwheat seed oil and buckwheat seed oil.Methods:
Fatty acids were obtained by the methods of KOH-EtOH(95%) saponification and treatment of inorganic acid. They were analyzed and determined by gas chromatography and GC/MS chromatography respectively.Results:
4-5 kinds of fatty acid were determined in both oils, and the content of unsaturated fatty acids in tatary buckwheat oil was 83.2% ( oleic acid 47.1%, linoleic acid 36.1%), buckwheat oil was 81.8% ( oleic acid 35.8% , linoleic acid 40.2% and linolenic acid 5.8%). The content of unsaponifiable matters in tartary buckwheat seed oil was 6.56%(?-sitosterol 54.37%), and in buckwheat seed oil was 21.90%(?-sitosterol 57.29%,?-tocopherol 1.41%).Conclusion:
Both buckwheat oils were functional vegetable oils.
