Abstract

Objective To study the fat constituents of the seed of Euphorbia Sororia.Methods The constituents were extracted by Soxhlet extraction method,then separated and identified by gas chromatograph mass spectrometer(GC-MS).Relative content of each component was determined by area normalization.Results Ten kinds of fatty acid were identified,the primary fatty acid composition of Euphorbia Sororia seed oil were palmitic acid(5.608%),stearic acid(2.219%),oleic acid(13.857%),linoleic acid(17.623%),a-Linolenic acid(50.854%).Conclusion Euphorbia Sororia seeds are in great value of development because of the abundant EFA(essential fatty acid).a-Linolenic acid and Linoleic acid have a 82% of the relative content in EFA from Euphorbia Sororia seeds oil.
