The paper studies the technique conditions for extracting chlorogenic acid from Passiflora eduist by Microwave extraction-HPLC.Adopting the method of orthogonal test with L9（34）,the extraction conditions for ex-tracting chlorogenic acid from Passiflora eduist are discussed,and such influencing factors as microwave power,extraction time,solvent concentration and the ratio of material to liquid were studied.The results show that the optimum technology conditions for extracting chlorogenic acid from Passiflora eduist by microwave-assisted method are as follows： microwave power of middle high fire,extraction time of 2 min,volume fraction of ethanol was 80%,and the ratio of material to liquid was 1∶10.Under these conditions,the extraction rate of chlorogenic acid from Passiflora eduist is 0.053%.
