In the present study, ethanol/NaH 2 PO 4 aqueous two-phase system (ATPS) was employed for the extraction and purification of flavones from honeysuckle. A Box-behnken design (BBD) was used to study the effects of salt concentration, ethanol concentration and pH on flavones partition behavior. The optimal system was found at pH 5.0, containing 4.6g NaH 2 PO 4 and 36%...
The separation/enrichment of tilmicosin was studied based on the system of aqueous two phase-gas solvent subblation, the method of HPLC was established to determin tilmicosin enriched. The optimal condition of the solvent sublation was obtained: the sublation solvent was n-propanol, the salting-out agent was (NH4)2SO4 with 36% (g/100ml), the pH was 3, N2 flow rate was 20 ml/min, the sublation time...
