Abstract


Repeated chromatographic separation and purification of the dichloromethane-methanol (1:1) extract
of the stem bark of Calophyllum inophyllum led to the isolation of four secondary metabolites which were identified
as β-friedelin (1), α-friedelan-3-ol (2), 4-hydroxyxanthone (3) and stigmast-5-en-3-one (4) by analysis of their NMR
data and comparison with published values.


Keywords
