| Abstract: | Objective： To seek for the optimum biphase dynamic extraction technology for puerarin from Radix Puerariae.Methods： Extraction ratio of puerarin as the major indicator and weight of extractum as minor indicator,an orthogonal experimental design by L9（34） was used to investigate the influence of sulfuric acid concentration,volume of solvent,hours and times of extraction on the content of puerarin.Results： Optimum extraction technology for puerarin is： 2.0% sulfuric acid,12 times of volume,at 100℃,2 times of extration and 1.5h per time.Conclusion： The optimized technology is stable and repeatable,helpful for quality control and mass production. |
