Study on Microwave Irradiation of Berberine from Rhizoma Coptidis / 中国中医药信息杂志

ABSTRACT

Objective Ethanol, acid and alkali were used in the traditional Bererine extracting which required quite a few extracting time and polluted the environment. Water instead of ethanol was used. Microwave irradiation was chosen as the extracting method. Methods The best parameters, microwave power, extracting time, solid-liquid ratio were got in the experiment. According to the orthogonal experimental design, the optimum extracting condition was determined. Results Microwave irradiation, compared with the traditional extracting techniques, was with short extracting time. Conclusion The method was practicable and the product possessed the virtue of high purity, safe quality and free pollution.
