Abstract:
AIM:To explore the extraction mechanism of the separation-purification of baicalin in aqueous two-phase systems. METHODS:By experiment,nonionic surfactant PEG-K_2PHO_4-H_2O two aqueous phase system was selected to phase-forming conditions,and the effect of temperature,pH,salt composition on partition of baicalin PEG/salt system. RESULTS:The extraction rate of baicalin in aqueous two-phase system was up to 98.6%. CONCLUSION:The two aqueous phase system for baicalin extraction is easy to operate has good reproductivity,and can be applied in mass production.
