Traditional extraction methods of total saponins of Panax notoginseng include cold soaking method,water decoction method,alcohol reflux method,percolation method,macroporous resin adsorption method,and accelerated solvent extraction( ASE) method. Modern extraction methods include ultrasonic extraction,microwave assisted extraction,supercritical CO_2 extraction,microbial fermentation assisted extraction,neural network model optimized extraction method,and multi-stage countercurrent extraction method. This paper discussed principles of these methods and compared their advantages and disadvantages.
