The compounds obtained from A. catechu pericarp were repeatedly purified by eluting with 5% dichloromethane in hexane with the polarity increased in 5% increments using dichloromethane, ethyl acetate, and methanol. The purification of compounds was assessed on TLC plates (Silica gel 60 F254pre-coated TLC aluminum sheets, Merck) using UV ?max254 and 316 detector, vanilline-H2SO4, and anisaldehyde standard spray reagents
