Abstract
This article study the application of Microwave - assisted Extraction in extracting alkaloids from RhizomaCoptidis. Single factor experiment has done to find out the infection of Microwave - assisted Extraction of alkaloids from RhizomaCoptidis via solvent, the temperature of MAE,the time of microwave and the ratio of solid and fluid. Best extractive condition was determinated. In addition, designed the orthogonal experiment, ascertain the optimal distill scheme and each factor of effect gradation with extract result. The result shows the following optimal extraction condition: microwave temperature is 60℃,microwave radiation time is 10min and stock ratio 10:1. The microwave assisted extraction can reduce the extraction time，but also through capillary electrophoresis，We found that alkaloids yield markedly improved. Get across extraction process with microwave - assisted extraction of analyse, it proves that MAE has the excellences of quick、no polluting、craftwork of briefness and high practicability.
