Dried pericarp of A. catechu was soaked for 5d in three organic solvents: hexane, ethyl acetate, and methanol. The crude extracts were separated by flash column chromatography over silica gel 60 (0.040–0.063mm) and elution with 10% dichloromethane in hexane with the polarity increased in 10% increments using dichloromethane, ethyl acetate, and methanol.
