Abstract:
Taking Polygala fallax as material,using the method of single factor test and orthogonal test,the effect of ultrasonic frequency,ultrasonic power,extracting time,extracting temperature,alcohol concentration and ratio of solid and liquid on extracting rate of flavonoid from Polygala fallax were studied,to optimize extracting technique.The results showed that the optimal extracting conditions were ultrasonic frequency 61 kHz,ultrasonic power 420 W,extracting temperature 55℃,the ration of solid and liquid 1∶15 g/mL,alcohol concentration 90%,extracting time 40 min.The stability and repeatability of this technique were good.It could provide the basis for extracting flavonoid from Polygala fallax.
