摘 要:目的运用Plackett-Burman实验设计联用星点设计(central composite design,CCD)效应面法,考察各影响因素显著性,筛选出大黄地上部位(aerial part of Rheum officinale Baill,APOR)总蒽醌及大黄素提取的最佳工艺,为非药用部位的开发与应用提供依据。方法运用Plackett-Burman实验设计筛选主要影响因素,采用CCD-效应面积法优选APOR蒽醌提取工艺。以乙醇体积分数、提取时间、料液比为自变量,总蒽醌和大黄素含量为因变量,通过对自变量与因变量的完全二次响应曲面的回归拟合,利用三维曲面图直观分析APOR蒽醌提取最佳工艺,并进行预测分析。结果总蒽醌的最佳提取工艺为:乙醇体积分数67.25%,时间90 min,料液比28∶1;大黄素的最佳提取工艺为:乙醇体积分数85%,时间90 min,料液比40∶1。结论利用Plackett-Burman实验设计联用CCD确定了APOR总蒽醌和大黄素的提取工艺,该方法简便,精度更高、重现性好、预测性强。OBJECTIVE To optimize the process of extacting effective constituents from aerial part of Rheum officinale Baill by Plackett-Burman design combined with CCD response surface methodology. METHODS In Plackett-Burman combined with CCD re- sponse surface design, the independent variables were concentration of ethanol, extraction time, and solvent fold. The dependent varia- bles were contents of total anthraquinone and rheum emodin. RESULTS The optimal extraction process of total anthraquinone was as follows: 67.25% ethanol, 90 min for reflux per time, 28:1 fold of solvent and 2 times of extraction; the optimal extraction process of emodin was 85% ethanol, 90 min for reflux per time,40 fold of solvent and 2 times of extration. CONCLUSION The optimal process is simpleand convenient for extracting aerial part of Rheum officinale Baill with high precision and predictability.
