摘要

本研究以中心复合设计(CCD)为基础,建立响应面法,并将其应用于黑荆灌木抗氧化成分提取的控制优化。在14次试验中评估了两种提取参数:甲醇:水(30% ~ 80%)和提取时间(4 ~ 6天)。多元回归分析的二次多项式方程预测了提取工艺的优化。试验09中,在甲醇(55%)和时间(6.41 d)为6.48 g/100g的条件下,获得最大抗氧化提取物(AE)。试验08在甲醇浓度为55%、提取时间为3.59 d时,获得了最低的自由基清除活性(ic50)值。结果表明,在最佳提取时间为6.41 d、溶剂浓度为76.01%、提取时间为6.62 g/100g、提取时间为1.66 g/mL的条件下,红叶AE产率和自由基清除活性(ic50)最优,总体理想度为0.96。根据响应优化方法,使产量最大化和DPPH最小化的条件在给定的限制条件内。实际值与预测值拟合良好,验证了回归模型的可接受性。响应面法(RSM)验证了该技术的有效性。

Applying an Optimization Technique for the Extraction of Antioxidant Components from Justicia adhatoda Leaves
In this research work, the response surface approach was constructed on a central composite design (CCD) and was applied to control optimization for antioxidant elements extraction from Justicia adhatoda shrubberies. Two extraction parameters were assessed in 14 experimental trials as methanol: water (30% to 80%) and the extraction time (4 to 6 days). The quadratic polynomial equation of multiple regression analysis forecasts the extraction process's optimization. The maximum antioxidant extract (AE) was obtained at methanol (55%) and time (6.41 days) 6.48 g/100g on trial 09. The minimum radical scavenging activity (IC 50 ) values were obtained at methanol (55%) and extraction time of 3.59 days on trial 08. It was found that the AE yields and radical scavenging activity (IC 50 ) of Justicia adhatoda leaves could be optimized at 6.62 g/100g and 1.66 μg/mL at the optimum condition at a time of 6.41 days and solvent concentration of 76.01% with overall desirability 0.96. According to the response optimizer method, the conditions that maximize the yield and minimize the DPPH are within the established restrictions. The well-fitted actual values to predicted values validate the regression model acceptability. Antioxidant properties of Justicia adhatoda leaves using response surface methodology (RSM) confirm this technique's usefulness.
