The highest TFC was obtained in the 100% ethanol extract, followed
by the 100% acetone extract, the 100% methanol
extract, and the water extract. A similar trend was observed
in the amount of TPC. As the concentration of water in
ethanol or acetone increases, the TFC in the extract decreases.
By contrast, the TFC in the 75% aqueous methanol
extract is higher than that in the 100% methanol extract and
the 50% aqueous methanol extract.
