摘要
通过正交实验和方差分析,采用快速溶剂萃取(ASE)法研究紫色山药中花色苷的提取温度、循环次数、冲洗体积及静态时间等因素对提取效率的影响。结果表明:快速溶剂萃取技术萃取紫山药花色苷的最佳提取条件为:温度80℃,循环提取4次,冲洗体积120%,静态时间2min,影响提取效率的主要因素是温度。该技术与常规溶剂提取法相比,具有提取时间短、溶剂用量少、萃取效率高等优点,具有潜在的开发应用价值。
The influence of temperature, cycling time, the solvent volumn and stable time on the extraction efficiency of anthocyanin in Purple yam were discussed by the method of accelerated solvent extraction using orthogonal experiments and the analysis of variance. The results showed that the separation and identify by HPLC, the best extraction condition was at 80℃, cycling four times, 120 % washing solvent and keeping 2 min. Meanwhile, the most important factor on extraction efficiency was the temperature. This technology had the advantage of saving time, little solvent consumption, high extraction efficiency etc,and would be developed in the future.
