摘　　要：目的优选三七的最佳渗漉提取工艺。方法采用正交试验法,以三七总皂苷和三七总氨基酸为考察指标,对影响三七渗漉提取工艺的因素进行研究。结果乙醇浓度、乙醇用量、渗漉速度均对三七提取工艺有显著影响。结论三七的最佳渗漉提取工艺为用12倍量50%乙醇,渗漉速度为1～3mL/(min·kg)。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）.
