【摘要】 用单因素试验和正交试验考察了料液比、提取时间、提取温度及乙醇浓度对五味子叶总黄酮含量的影响。结果表明:料液比为1:35,75%乙醇在85℃超声提取60min,为最佳条件;此条件下,7月份和8月份五味子叶的总黄酮平均含量分别为6．0285mg/g和8．0714mg/g。更多还原

【Abstract】 The optimum extracting conditions of flavones in Schisandra chinensis(Turcz.)Baill leaves were investigated by single factor test with the orthogonal test design.The main factors affecting the content of total flavones extracted from Schisandra chinensis(Turcz.)Baill leaves were the material-liquid ratio,the extraction temperature,the extraction time and the alcohol concentration.The results showed that the optimum conditions were:85℃,60min,75% alcohol and material-liquid ratio 1:35. Under the conditions,the contents of total flavones in Schisandra chinensis(Turcz.)Baill leaves collected in both July and August are 6.0285mg/g and 8.0714mg/g,respectively.更多还原
