摘要: 以白藜芦醇和白藜芦醇苷的总量为指标,考察了超声、加热回流、快速溶剂萃取(ASE)三种提取方法对青海栽培何首乌中白藜芦醇和白藜芦醇苷提取效果的影响,通过单因素实验和响应面法优化ASE的提取条件,在单因素实验基础上筛选出乙醇浓度、提取温度、提取时间三个主要因素。结果表明,ASE在提取效果上优于其他两种方法,通过响应面分析得出最佳组合条件为:乙醇浓度51%,提取温度96 ℃、提取时间16 min。快速溶剂萃取法简单、快捷、高效,适用于何首乌中白藜芦醇和白藜芦醇苷的提取。

Abstract: The total content of resveratrol and polydatin was used as the investigation index.The efficiency of ultrasonic extraction,heating reflux extraction and accelerated solvent extraction (ASE) for the extraction of resveratrol and polydatin in cultivated Polygonum multiflorum from Qinghai was compared.The extraction conditions of ASE were optimized through single-factor test and response surface methodology (RSM).To obtain the maximum of extraction yield of resveratrol and polydatin, three main factors including ethanol concentration,extraction temperature and extraction time were selected and further optimized using RSM on the basis of single factor experimental results.As a result,ASE was markedly superior to the other two methods.The optimal conditions of ASE were as follows:51% of aqueous ethanol,extraction temperature of 96 ℃,and extraction time of 16 min.ASE was simple,rapid and efficient,and was appropriate for the extraction of resveratrol and polydatin in P.multiflorum.

Key words: cultivated Polygonum multiflorum, resveratrol, polydatin, accelerated solvent extraction, response surface methodology
