ABSTRACT
AIM: To investigate and optimize the technology of ultrasonic-assisted extraction of arctiin and arctigenin from Fructus arctii.METHODS: The effects of ultrasonic power,particle size,ratio of liquid to solid,extraction time,extraction temperature and duty factor on the extraction rates of arctiin and arctigenin were investigated,and optimized with orthogonal experiments.RESULTS: The results showed that the optimal extraction conditions were as follows: particle 80 ~ 100 mesh 14 mL/g,ratio of liquid to solid 400 W ultrasonic power,50 ℃ of extraction temperature,and 10 min of extraction time.CONCLUSION: The optimized conditions are reasonable and reliable.
