Abstract：The experiment aimed to investigate the in vitro antioxidant activity of the oil from the eggs of the Quasipaa spinosa.The eggs of the Quasipaa spinosa were used as raw material,and the oil was extracted using the Soxhlet extraction method.The extraction process was optimized through orthogonal experiments,and the extracted oil was tested for in vitro antioxidant activity.The results showed that the optimal extraction conditions obtained from the orthogonal experiment were:Using petroleum ether(60～90)as the extraction solvent,an extraction temperature of 75 ℃,a liquid-to-solid ratio of 24 mL/g,and continuous extraction for 7 hours.In vitro antioxidant tests revealed that the half-inhibition concentration(IC50 value)of the Quasipaa spinosa egg oil against DPPH radicals was 298.907 g/L,the IC50 value for scavenging hydroxyl radicals was 1.176 g/L,and the IC5()value for scavenging superoxide anion radicals was 12.400 g/L.The study indicates that the oil from the eggs of Quasipaa spinosa possesses certain in vitro antioxidant properties and has potential application value in the field of natural antioxidants.
