Abstract: General Phytochemical screening of the aerial parts of Canarium schweinfurthii revealed the presence of triterpenes. Extensive Phytochemical investigation of the chloroform and ethylaceate extract of the rhizome afforded compounds which were identified by I.R, 1HNMR and 13CNMR. Pentacyclic triterpenoids of three different classes; oleanane-type triterpene, ursane-type triterpene, and lupine-type triterpene were isolated from the methanol extract of the aerial parts of Canarium schweinfurthii. On the basis of their spectroscopic data, their structures were elucidated on the basis of physical and spectral techniques, besides comparison with literature data. The structure of the isolated compounds 1, 2 and 3 were established as 3β-hydroxyl olean-12, 18-diene (β-amyrin), 3β-hydroxyllup-20(29)-en-28-oic acid (Betulinic acid) and 3β-hydroxyl ursa-5,11,19-triene (uvaol) respectively. The compounds are reported for the first time from this plant.
