Along with other therapeutic applications, The Ayurvedic Pharmacopoeia of India indicates the use of stembark in phosphaturia and recommends it as a blood purifier.Alstonia sp. is known as Fever Bark. A. constricta is native to Australia; A. scholaris to Australia and Southeast Asia. The bark of both the species contains indole alkaloids. A. constric- ta contains reserpine (a hyptotensive agent). A. scholaris contains echita- mine, which has also demonstrated hypotensive effects. Though A. schol- aris produces fall in the temperature of human patients with fever, there are conflicting reports about the activity of echitamine against Plasmodium berghei.Dosage: Stembark—20-30 g for decoction.

The plant is a rich source of indole alkaloids. Major alkaloids in the stem- bark are alstovenine, venenatine, 3- dehydroalstovenine, reserpine (0.0030.3%), venoxidine and kopsinine.Alstovenine, in lower doses, exhibits monoamine oxidase inhibitor activity; in higher doses, shows marked central stimulant effect (reversal of reserpine effects). Venenatine exhibits reserpine- like profile of activity (sedation, ptosis, reduction in motor activity).The fruit contains vincadifformine type of alkaloids. Echitovenidine, the major alkaloid, shows monoamine oxidase-inhibitory activity both in vitro and in vivo.... alstonia venenata
