Two novel cycloartane triterpenoid, 25 methoxylcycloartane-3beta, 24-diol and 25 methoxyl-28 norcycloartane -3beta, 24-diol together with a known triterpenoid, lupeol were isolated from the leaves of Aglaia chittagonga family meliaceae. The structures and relative stereochemistry of the compounds were elucidated through extensive analysis of their IR, MS, 1H and 13C NMR spectral data, especially 1-D and 2-D NMR as well as comparison with those value of known related compounds.
