摘要
采用中心组合设计方法优化莽吉柿果皮中总氧杂蒽酮的提取工艺,研究乙醇体积分数、超声时间、液固比及其交互作用对总氧杂蒽酮提取率的影响。应用SAS软件和响应面分析相结合的方法,模拟得到回归方程的预测模型和可信度,并通过岭脊分析得到最佳的提取条件为乙醇体积分数90.9%、超声时间73.8min、液固比17.1:1(mL/g)。该条件下提取率为7.73%。
A central composite design（CCD） was used to optimize the ultrasonic-assisted extraction of total xanthones from mangosteen pericarp.The effects of ethanol concentration,ultrasonication time and solvent-to-solid ratio as well as their interactions on the extraction rate of total xanthones were investigated.A predictive regression model was developed using the SAS software by response surface analysis and its reliability was validated.The optimal extraction conditions were 90.9% of ethanol concentration,17.1：1（mL/g） of solvent-to-solid ratio and 73.8 min of ultrasonication time as determined by ridge analysis,resulting in an average actual yield of total xanthones of 7.73%（n = 3）.
