The influences of 1-propanol and magnesium sulfate concentration and Tie line Length (TLL) were investigated to obtain the optimal partitioning and recovery of GL and IGL into the top-phase and ACN and HCA to the bottom phase. The 25% w/w 1-propanol and 12% w/w magnesium sulfate system showed the maximum extraction efficiency for all the compounds. The purity and recovery were further improved by employing the second stage ATPS. © 2020 Taylor & Francis Group, LLC.Sulfur compounds1-propanolAqueous biphasic systemBioactive compoundsExtraction efficienciesGarcinia indicaHydroxycitric acidsMagnesium sulfateOptimal partitioningMagnesium compounds
