Enhanced extraction of phenolic compounds from pericarps of mangosteen by subcritical water treatment was performed at various temperatures and pressures of 120-160 degrees C and 1-10 MPa in batch and semi batch systems. Instead of water, the deionized water which contains deep eutectic solvent at 10-30% volume was used as an extraction media. With 30% of deep eutectic solvent addition, the yields of xanthone and phenolic compounds content were 24.87 mg/g dried sample and 179.54 mg of gallic acid equivalent (GAE)/g dried sample at extraction temperatures of 160 and 120 degrees C in batch system, respectively. They could achieve to 27.15 mg/g dried sample and 372.69 mg of GAE/g dried sample when the extraction were performed in semi batch system at temperature of 160 degrees C and pressures of 5 and 10 MPa with 10 and 30% of deep eutectic solvent addition, respectively.
