A prenylated xanthone is a nonpolar compound, which could be extracted from mangosteen pericarp by ethanol solvent (Jung et al., 2006). The polarity of ethanol increased with the addition of water. Thus, the decreasing of water proportion in the mixture of water and ethanol enhanced TPC yield.
How do you extract mangosteen pericarp?
The pericarp of mangosteen was dried at 60°C for 2 days and pulverized by a grinder. It was further extracted by ethanol for 4 days. The extract was evaporated at 45°C by an evaporator. The crude ethanol extract was partitioned with ethyl acetate to 2 : 1 weight : volume for 2 days.
