摘要
采用溶剂回流提取的方法,以红松树皮中原花青素的提取率为考察指标,考察了提取溶剂种类、溶剂浓度、提取温度、料液比、提取时间、提取次数等因素对原花青素提取效果的影响。通过正交实验,确定红松树皮中原花青素的最佳提取工艺条件为:提取溶剂60%乙醇,提取温度50℃,料液比1:7,提取时间60min。
The solvent reflux extraction process for proanthocyanidins from Pinus koraiensis Bark was optimized by orthogonal design with L9(34) model.The extraction yield of proanthocyanidins was regarded as the index of examination.The influence of the extraction solvent concentration,temperature,solid-liquid ratio and extracting time were investigated herein.Optimum extraction conditions were determined as follows:extracting solvent was 60% ethanol,extracting temperature was 50 ℃,solid-liquid ratio was 1∶7,extracti...
