Abstract
A method of making, separating, and purifying artepillin C in propolis includes mixing propolis with ethanol to obtain a propolis-ethanol extract; providing supercritical carbon dioxide and the propolis-ethanol extract to a chromatographic column to separate wax, artepillin C, and flavonoids; providing supercritical carbon dioxide, the artepillin C, and the flavonoids to an adsorption column to remove the flavonoids; keeping the adsorption column still; and providing ethanol to the adsorption column to obtain the purified artepillin C.
