H.Chen. Methods Conditions for the extraction were studied by orthogonal experimental design asguided by thecontent of total notoginseng saponin presentin the extract. ResultsSignificant effect wasobserved in 3different experimentalconditions. Conclusion Theoptimum condition for theextraction ofP. notoginseng was tosoak thedrugin75% alcoholfor 24h and then percolateat arateof 1 3ml/min tocollect an amountcorresponding toabout 10times of thequantity of P.notoginseng.Key words: orthogonal experiment; Panax notoginseng (Burk.)
