Abstract: Objective: To extract blackberry seed oil from blackberry seeds with supercritical carbon dioxide and determine its fatty acid composition. Methods: Operating parameters that influence the extraction of blackberry seed oil were optimized using an orthogonal array design. The fatty acid composition of blackberry seed oil was analyzed by gas chromatography-mass spectrometry (GC-MS). Results: The optimal extraction conditions were extraction temperature of 35 ℃, extraction pressure of 12 MPa, separation pressure of 12 MPa and separation temperature of 55 ℃. Under thess conditions, the yield of blackberry seed oil was up to 16.10%. The major fatty acids were palmic acid (5.38%), stearic acid (3.53%), oleic acid (13.70%), linoleic acid (60.48%), gamma-linolenic acid (11.16%) and total unsaturated fatty acid (85.34%).

Key words: supercritical carbon dioxide, extraction, blackberry seed oil, gas chromatography-mass spectrometry (GC-MS), fatty acid
