摘要:

以澳洲坚果青皮为原料,研究了超声辅助提取总黄酮工艺条件以及抗氧化活性。通过L9(3 4)正交试验得到超声功率为300 W条件下的最佳提取工艺:提取时间为45 min、乙醇浓度为50%、提取温度为50 ℃、料液比为1:60 (g/mL),在此条件下总黄酮提取量为(1638.59±44.26) mg/100 g。通过抗氧化实验发现,澳洲坚果青皮总黄酮ABTS自由清除能力约为Trolox的2.48倍,总抗氧化还原能力约为Trolox的1.90倍,由此表明澳洲坚果青皮总黄酮具有较强的抗氧化活性。

Abstract:

The study focused on the optimization of the ultrasonic-assisted extraction and antioxidant activity of total flavonoids from macadamia green peel. An orthogonal test with four factors and three level was carried out and the optimized conditions were: ultrasonic extraction time 45 min, ethanol content 40%, extraction temperature 50 ℃, solid-liquid ratio 1:60 (g/mL). The total flavonoids yield was up to (1638.43±44.26) mg/100g under the optimized conditions. The ABTS radical scavenging and total antioxidant capacity was about 2.48, 1.90 times of Trolox. The results indicated that the total flavonoids from macadamia green peel had strong antioxidant capacity.

Key words: macadamia green peel, ultrasonic-assisted, total flavonoids, antioxidant
