Study on Methods of Extract and Determine of Flavonoid From Toona sinesis
Objective: Flavonoids were extracted from Toona sinesis successfully.Method:Flavonoids were extract
By using the method of dissolved in alkali and separated out in acid and microwave.All the flavonoids in Toona sinesis were determined by UV-spectrophotometry with rutin as the standard and the quantities of flavonoids component were measured.And use L9(34) orthogonal test design.Result:It showed that the optimum extracting conditions were determined with 0.5%(M /V) Na2B4O7.10 H2O as extractor with the ratio of material to liquid at 1 g∶ 40 mL
and extracting for 30min /time and the separation temperature is 60 ℃.Conclusion:This study provided scientific basis for Toona sinesis
