The leaves of Buchanania Lanzan (Anacardiaceae) are reported to be of great medicinal importance. Isolation of chemical constituents was carried out from the leaves of Buchanaia lanzan, an evergreen member of the family anacardiaceae, using column chromatography. Identification of chemical constituents was done by MP, IR, NMR & LC-MS techniques. Three compounds ie pinitol, vomicine and celidoniol were isolated from the methanolic extract. These findings are useful in establishing a relationship between chemical composition of the leaf extract and previously reported activities of B. lanzan and also may assign a new potential role of B. lanzan extract in human health care.
