| Abstract: | Objective To optimize the ultrasonic extraction process of oleanic acid from Forsythia Suspensa flowers.Methods The ultrasonic extraction conditions for extracting the oleanic acid of Forsythia Suspensa flowers were studied by the orthogonal design and the effects of extraction time,ethanol concentration,solvent consumption and extraction times on oleanic acid yield were examined.Results Ultrasonic extraction times and ethanol concentration had the most significant effect.The factors affecting oleanic acid yield was in the order of ethanol concentration,ultrasonic extraction times,solvent consumption,extraction time and the best ultrasonic extraction process was to extract 3 times with twelve times of 85% ethanol for 60 minutes each time.Conclusion The extraction process is simple with good extract result. |
