Object To optimize the conditions for the extraction of Panax notoginseng (Burk.) F.H.Chen. Methods Conditions for the extraction were studied by orthogonal experimental design as guided by the content of total notoginseng saponin present in the extract. Results Significant effect was observed in 3 different experimental conditions. Conclusion The optimum condition for the extraction of P. notoginseng was to soak the drug in 75% alcohol for 24 h and then percolate at a rate of 1~3 ml/min to collect an amount corresponding to about 10 times of the quantity of P.notoginseng.
