Abstract

Pressurized liquid extraction (PLE) has been optimized for the determination of polyphenols in Golden Delicious apple peel and pulp. The effects of experimental variables, such as solvent composition, temperature, static extraction time and pressure, on PLE efficiency have been studied. Once the optimum conditions were established the recovery and the precision of the method for each analyte was tested by means of repeated analysis.

摘要

加压液体萃取(PLE)已针对金冠苹果果皮和果肉中多酚的测定进行了优化。研究了溶剂组成、温度、静态萃取时间和压力等实验变量对PLE效率的影响。确定最佳条件后,通过重复分析对每种分析物方法的回收率和精密度进行了测试。
