Alstonia venenata R.Br.

Alstonia venenata is a plant of the family Apocynaceae. It grows as a shrub or small tree in low to mid elevation deciduous forests of India. ^[1] The bark of the plant and, sometimes, the fruit, are used for medicinal purposes.

Alkaloids

Venenatine [1055-75-0]

Stigmasterol, reserpine, and two new indole alkaloids, venenatine and isovenenatine, were isolated from the bark. ^[2]

A pair of alkaloids were discovered in the fruits of this plant called echitovenidine and (+)-minovincinine: ^[3]

Echitoserpidine is another alkaloid discovered in the fruits of this plant. ^[4]
