water treatment was performed at various temperatures and pressures of 120–160° 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 …
