Study on Percolation Extraction Process of Panax Notoginseng / 中国中医药信息杂志

ABSTRACT

Objective To optimize the conditions for the percolation extraction process of Panax notoginseng(Burk.) F.H.Chen.Methods Conditions for the percolation were studied by orthogonal experimental design as guided by the contents of total notoginseng saponin and total amino acids.Results The percolate rate,concentration and quantity of alcohol had significant effects on the process.Conclusion The optimum condition for the extraction of Panax notoginseng was adding 12 times amount of 50% alcohol and percolating at a rate of 1～3 mL/(min?kg).
