Study on the process for flavonoids extracted from the leaves of Acer truncatum bunge by supersonic
Extracted flavonoids by supersonic from leaves of Acer truncatum bunge was studied.And the effect of extracting amount by changing the solvent concentration,extracting time,proportion of the material and solution was discussed.The effect of extraction was compared with traditional methods.The results showed that the extracting by supersonic treatment had many advantages,such as higher extracting rate and efficiency for the saving of time and cost.
