Abstract: Ultrasonic extraction of lignans from Eucommia ulmoides Oliv. was studied. Three main factors including EtOH volume fraction, ratio of liquor to material and extraction time on extraction rate of lignans were investigated using single factor analysis. The optimal processing conditions for ultrasonic extraction of lignans from Eucommia ulmoides Oliv. were obtained by orthogonal tests. The results showed that the optimum parameters were the mass of Eucommia bark about 1 g EtOH volume fraction 65%, ratio of liquor to material 20:1(mL:g), ultrasonic extracting for 45 min once after soaking for 12 h. The yield of lignans was 7.652% and extraction rate was 97.78%.
