Description of the Plant:
A large deciduous or semideciduous tree with buttressed and fluted trunk. Leaves sub-opposite, 10-15 cm long, elliptic-oblong, tip blunt or very shortly acute. Flowers very small, sessile, yellowish, in short axillary spikes or in erect terminal panicles. Fruits obovoid or oblong, 2.5-3.5 cm long with 5-7 narrow wings.
Bark is cardiac tonic, astringent, diuretic and febrifuge; useful in diseases of the heart, anaemia, excessive perspiration, dysentery, asthma, hypertension, wounds, skin eruptions, menstrual problems, pains and leucorrhoea. It is also used in the treatment of red and swollen mouth, tongue and gums. It stops bleeding and pus formation in the gums. The bark extract is given to drink for the cure of dysentery in Chittagong.
EtOH extract of the bark has been found to produce vasorelaxant, antifertility and hypocholesterolaemic effects in rats (Ghani, 2003). It has antioxidant and hypocholesterolaemic effects on man (Gupta et al., 2001). Recent studies proved that the bark has a salutary effect in patients with severe refractory heart failure (Bharani et al., 1995), and it is fairly effective in patients with symptoms of stable angina pectoris (Dwivedi & Agerwal, 1994).
The bark constitutes an important crude drug, which contains tannins, triterpenoids saponins, esters, flavonoids, sterols, calcium salts, alkaloidal and glycosidal substances, arjunine and arjunglycoside, arjunin, a sapogenin, arjungenin; a flavone, arjunolone, a methylated flavone, arjunone, terpene acids, arjunolic, terminoic and tomentosic acids, a phenolic substance, ellagic acid, sitosterol, β-sitosterol and oxalic acid. It also contains a lactone, essential oil, reducing sugars, arjunalic acid saponin and (+)-leucodelphinidin. The cancer-cell growth inhibitory constituents, gallic acid, ethyl gallate and luteolin have also been found to occur in the bark. A triterpene diglucoside, terminolitin, has been isolated from the fruits (Ghani, 2003; Rastogi & Mehritra, 1993).
