一种同时分离南方红豆杉叶中多糖和挥发 油方法的开发
evelopment of a method for simultaneous separation of polysaccharides and essential oils from the leaves of Taxus chinensis var. mairei
采用离子液体微波蒸馏同时萃取法同步提取了南方红豆杉叶中的多糖和挥发油。应用单因素和中心组合设计实验对此方法的主要操作参数进行了优化，获得优化条件：原料粒径为60-80目、液固比为22.5 mL/g、提取时间为17.5min、微波功率为547W、挥发油萃取溶剂为二氯甲烷。在此优化条件下，多糖和挥发油的提取率分别为6.39% 和0.27%。本实验方法与传统蒸馏提取、热回流提取相比，提取时间短、提取率高。因此，离子液体微波蒸馏同时萃取法是一种高效分离南方红豆杉叶中多糖和精油的方法。?????
n microwave-assisted simultaneous distillation and extraction (MA-SDE) method has been developed for the separation of polysaccharides and essential oil from Taxus chinensis var. mairei. The key operating parameters for MA-SDE were optimized by single factor and central composite design experiments, and the optimal conditions were found to include a particle size of 60-80 mesh, liquid/solid ratio of 22.5 mL/g, extraction time of 17.5 min, microwave power of 547 W, and dichloromethane was used as the extraction solvent of the essential oil. The yields obtained for polysaccharides and essential oil under the optimized conditions were 6.39% and 0.27%, respectively. Compared with conventional heat reflux extraction (HRE) and hydrodistillation extraction (HDE), the MA-SDE method completed the task with a much shorter extraction time and gave increased extraction yields for polysaccharides and essential oil. The MA-SDE method represents a rapid and efficient technique for the simultaneous extraction of polysaccharides and essential oil.
