摘要: 为优化广西地不容(Stephania kwangsiensis H. S. Lo)块茎总黄酮提取工艺,并探索其体外抗氧化活性。在单因素试验的基础上,采用正交试验法考察乙醇浓度、料液比、提取温度及超声时间对总黄酮提取率的影响,确定最佳提取工艺,并对总黄酮的体外抗氧化活性进行研究。结果表明,广西地不容块茎总黄酮的最佳提取工艺条件为乙醇浓度70%、料液比1∶35(g/mL)、提取温度50 ℃、超声时间50 min,在此条件下,总黄酮含量得率可达5.45 mg/g。广西地不容总黄酮具有较强的抗氧化活性,对1,1-二苯基-2-三硝基苯肼(DPPH)自由基的清除率可高达(84.39±0.61)%。研究利用超声辅助和紫外分光光度计法进行的总黄酮提取工艺方法简单,结果可靠,总黄酮具有良好的抗氧化性,该方法可为广西地不容总黄酮提取和开发应用提供较好的理论参考。

Abstract: To optimize the extraction process of total flavonoids from the tubers of Stephania kwangsiensis H. S. Lo and explore its in vitro antioxidant activity, based on single-factor experiments, an orthogonal test method was used to investigate the effects of ethanol concentration, solid-liquid ratio, extraction temperature, and ultrasonic time on the extraction rate of total flavonoids. The optimal extraction process was determined, and the in vitro antioxidant activity of total flavonoids was further studied. The results showed that the optimal extraction condition for total flavonoids from the tubers of Stephania kwangsiensis H. S. Lo was ethanol concentration of 70%, solid-liquid ratio of 1∶; 35 (g/mL), extraction temperature of 50 ℃, and ultrasonic time of 50 min. Under this condition, the yield of total flavonoids content could reach up to 5.45 mg/g. The total flavonoids from Stephania Kwangsiensis H. S. Lo exhibited strong antioxidant activity, with the scavenging rate against 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals reaching up to (84.39±; 0.61)%. In this study, the ultrasound-assisted extraction process of total flavonoids coupled with ultraviolet spectrophotometry was simple and yielded reliable results. Given that the total flavonoids possessed good antioxidant properties, this method could provide a sound theoretical reference for the extraction, development, and application of total flavonoids from Stephania kwangsiensis H. S. Lo.
