Abstract: The main objective of this work is isolation and characterization of chemical compounds with biological studies from the leaves of Ravenea rivularis (Arecaceae). Materials and Methods: The air dried plants extracted with70% methanol, n-hexane, ethyl acetate and n-butanol. The compounds were isolated by column chromatography, TLC, PTLC and paper chromatography. The isolated compounds were identified by spectroscopic methods as 1H NMR, UV and MS. Results: The compounds identified are Lupeol acetate, Betulinic acid, Apigenin, Luteolin, luteolin-7-O-β-D-glucopyranoside, ferulic acid, caffeic acid and chlorogenic acid. The leave extracts from Ravenea rivularis exhibited antioxidant activity, anti-inflammatory and cytotoxicity against Hep-G2. All those compounds are been reported for the first time in Ravenea rivularis.
