摘要:以桂圆果核为研究对象,采用超声提取桂圆果核黄酮,通过单因素试验及正交试验优化确定最佳提取工艺条件,并研究其抗氧化活性。研究结果表明,桂圆果核黄酮的最佳提取工艺条件:乙醇浓度为70%、提取温度为40 ℃、料液比为1∶30 g/mL、提取时间为60 min,平均黄酮提取率为5.17%,该提取工艺简便高效,稳定可行。在一定浓度范围内,桂圆果核黄酮对DPPH自由基、ABTS+自由基、羟基自由基的清除能力以及还原力均随黄酮提取液质量浓度的升高而增强,表明桂圆果核黄酮具有一定的抗氧化活性。该结果为桂圆果核黄酮工业化提取奠定一定的理论基础。

Abstract:The flavonoids from longan kernel were extracted by ultrasonography, and the optimal extraction conditions were determined by single factor test and orthogonal test, and the antioxidant activity of longan kernel was studied. The results showed that the optimal extraction conditions were as follows: ethanol concentration of 70%, extraction temperature of 40 ℃, solid-liquid ratio of 1∶30 g/mL, extraction time of 60 min, average extraction rate of flavonoids was 5.17%. The extraction process was simple, efficient, stable and feasible. In a certain concentration range, the scavenging ability of longan kernel flavonoids on DPPH free radicals, ABTS+ free radicals and hydroxyl free radicals and the reducing ability of flavonoids were enhanced with the increase of the concentration of flavonoids extract, which indicated that longan kernel flavonoids had certain antioxidant activities. The results provided a theoretical basis for industrial extraction of flavone from longan kernel.
