METHODS With the absorbance of volatile oils and the content of in Bupleurum chinense DC as indexes, selecting the major influencing factors and levels by the single factor experiment, and selecting the optimum technology by orthogonal experiment. RESULT The optimum condition shows the impregnating temperature is 40℃ ,the volume of distilled fluid is 2 times of weight of Bupleurum chinense DC, and the volume of 95%alcohol with 5%ammonia water to reflux extraction for 1hour is 8 times of weight of Bupleurum chinense DC, then the absorbance of volatile oils is 0.941 and the content of saikosaponin a is 0.32%.CONCLUSION The optimum technology provides reliable evidence for extraction of active ingredients from Bupuleurum chinense DC, and the conditions are accurate and reliable with good reproducibility。KEY WORDS：Extraction technology; saikos...
