Abstract
The objectives of this study were to investigate the antioxidant activity of Schizandra chinensis seed oil and its active ingredients. Schizandra chinensis seed oil content extracted with hexane was 36.06%. Schizandra chinensis seed oil extracted with hexane was purified during 20 min at 85℃ with phosphoric acid 0.15% for degumming and 20 min at 80℃ with 3 M NaOH 1% for deaciding. The purified oil consisted of unsaturated fatty acid (88.7%), fatty acid (9.97%), and so on. The major unsaturated fatty acids of purified oil were linoleic acid (71.1%) followed by oleic acid (15.7%), while the main saturated fatty acid was palmitic acid (6.56%). The purified oil was found that contents of phenolic compounds, vitamin A, and E were 1.45 g/100 g, 1494.86 RE/100 g, and 0.58 ㎎ α-TE/100 g, respectively. Schizandra chinensis seed oil exhibited strong antioxidant activity (91.7%) as compared to grape seed oil and canola seed oil with 87.4% and 85.1% in the DPPH assays. Present results suggest that Schizandra chinensis seed oil could be potentially used as bioactive source for health and preventing numerous diseases.
