Methods of extraction and separation of antioxidants from plant sources by chromatography and solvent extraction are often time and solvent consuming, and result in low yields. A simple and mild thermo-induced aqueous micellar biphasic system (AMBS) was used to recover alpha- and gamma-mangostins from Garcinia managostana peels. AMBS composed of non-ionic surfactants such as Triton X-114, Triton X-45, and Pluronic triblock copolymers were developed. Effects of the types of the non-ionic surfactant, its concentration, sample load, pH of the AMBS and the equilibration temperature on recovery of mangostins were studied. The optimum condition for recovery of alpha- and gamma-mangostins was achieved with an AMBS composed of 3% (w/w) Pluronic L-81 and a sample loading of 0.5% (w/w) crude peels. At equilibration temperature of 40 degrees C and pH 8, 2646.6 +/- 1.2 mu g/mL of a-mangostin and 379.4 +/- 1.2 mu g/mL of gamma-mangostin were recovered in the micelle-rich phase of the AMBS with a log partition coefficient of alpha- (log K-gamma) and gamma-mangostin (log K-gamma) of 4.00 +/- 0.02 and 3.36 +/- 0.01; respectively. alpha- and gamma-mangostins could be recovered simultaneously with a yield of 52.93% and 7.59%, respectively in a single-step. This study demonstrated that AMBS can serve as a tool to efficiently recover and separate various bioactive compounds from plant sources. (C) 2017 Institution of Chemical Engineers.
