Abstract:
Using Platycodon grandiflorum stems as experimental material，aqueous two-phase assisted with microwave method was applied to explore the influence of many factors on the total saponins extraction efficiency and its antioxidant ability in vitro.The results showed that the optimum ratio between material and solvent，the microwave power，the ratio between ethanol and water，extraction time and the mass concentration of ammonium sulfate were 1∶25 g/mL，600 W，0.77，7 min and 0.21 g/mL,respectively.Under optimum process condition，the average total saponins extraction efficiency reached 92.31%.The activity test showed that total saponins extraction solution from Platycodon grandiflorum stems had certain antioxidant ability in vitro，which might gradually enhance the clearance ratio with the increase of mass concentration of total saponins in extraction solution.
