yield of MPEE was 23.2% (w/w) in this current study. A previous
study reported that the yield of extracts from the mangosteen pericarp was 2.0%, 6.1%, 6.2% and 22.3% (w/w) when extraction was
carried out at RT for 7 days with 50% ethanol, 95% ethanol, ethyl
acetate and water, respectively (Weecharangsan et al., 2006).
Therefore, higher total phenolics recovery was obtained when
extraction was carried out at higher temperature in the same
solvent system. This may be because the increase in temperature
