柿叶精油的提取工艺研究

摘要

以柿叶为原料,用石油醚提取精油.结果表明,最佳提取工艺条件是:提取温度50℃,提取时间2h,料液比1:12(g/mL),提取率可达3.80％,RSD为0.430％.%Persimmon leaf as raw material, essential oil extracted with petroleum ether. The results showed that the optimal extraction condition were: extraction temperature 50? , extraction time 2 h, solid-liquid ratio 1 :12,the yield 3.80% ,RSD 0.430%.
