 Leaf oil composed of sesquiterpene derivatives: allo-aromadendrene, caryophyllene oxide, ß-caryophyllene, ß-selinene, a-humulene and ar-curcumene. 
• Phytochemical study on the hexane extract of the stem bark led to characterization of clerodane and ent-halimane deiterpenes, two of which have shown antibacterial and antifungal activities.
• Preliminary studies of seeds showed a rich source of alkaloids, tannins, phenols, flavonoids, and carbohydrates. 
• Elemental analysis of seeds and leaves revealed large amounts of zinc, copper, iron, and manganese, in larger amounts in the leaves than in the seed. Nitrogen, phosphorus, and potash were present in negligible amounts. 
• Elemental analysis of leaves (L) and seeds (S) yielded nitrogen 1.05% L, 0.91% S; phosphorus 0.08% L, 0.11% S; potash 0.31% L, 0.40%; zinc 42.0ppm L, 44.0ppm S; copper 163.0ppm L,120.0ppm S; iron 204.0ppm L, 125.0ppm S; and manganese 312.0 ppm L, 8.0 ppm S. 
• Phytochemical screening of ripe and unripe pericarp yielded the presence of flavonoids, saponins, steroids, glycosides, and tannins in both extracts. Terpenoids and alkaloids were not detected
