| Abstract: |
| In order to tap the potential development and utilization value of Lycium ruthenicum seed oil, Lycium ruthenicum seed oil was extracted by petroleum ether, and its physicochemical properties, fatty acid composition and content , DPPH· and ABTS+· scavenging power, and total reducing power were analyzed . The results showed that the iodine value, saponification value, peroxide value and acid value of Lycium ruthenicum seed oil were (84.0±0.2)gI/100 g, (130.1±0.3)mgKOH/g, (0.42±0.03) g/100 g, and (8.4±0.2) mgKOH/g, respectively, and it needed to be further refined. Lycium ruthenicum seed oil contained 9 kinds of fatty acids, such as linoleic acid (68.31%), oleic acid (17.76%), palmitic acid (5.37%), γ-linolenic acid (3.73%), and stearic acid (2.58%) and so on. The IC50 of Lycium ruthenicum seed oil for DPPH·scavenging rate was 0.587 mg/mL, the ABTS+· scavenging rate of 3.2 mg/mL Lycium ruthenicum seed oil was 57.50%，and it had a certain Fe3+ reduction power. Lycium ruthenicum seed oil is rich in unsaturated fatty acids, and it has good in vitro antioxidant activity, so it has development value and potential. |
