Description of the Plant:
A tall handsome, evergreen tree with a conical crown. Leaves 7-20 cm long, narrowly lanceolate with wavy edges. Flowers 2.5-3.8 cm across, yellowish green, in fasciles or short umbels from the axils of fallen leaves; petals subequal, linear, spreading, tapering to a point. Fruits 18 mm long, ovoid, produced in great clusteres on glabrous stalks, black when ripe.
The bark is used as a febrifuge in the treatment of fever. Alcoholic extract of the leaf possesses strong antifungal and antibacterial properties against wide range of pathogens (Taniya, 2004).
Leaves have been reported to contain an azafluorene alkaloid, polylongine and three aporphine N-oxide alkaloids, (+)-O-methylbulbocapnine- α-N-oxide, (+)-O-methyl bulbocapnine- β-N-Oxide and (+)-N-methylnandigerine- β-N-oxide. Pentacyclic triterpenes, tarexasterol, stigmasterol, β-sitosterol, campesterol, α-amyrine and β-amyrin have also been identified in the leaves. Clerodane diterpenoids have been isolated from the bark and seeds of this plant (Ghani, 2003). A new proanthocyanidin (I) along with β-sitosterol and leucocyanidin have been isolated from stem bark (Rastogi & Mehrotra, 1993).
