Tabernaemontana elegans is a shrub or small tree that is native to eastern Africa. Vernacular names for the plant include "Toad tree".

Structure[edit]

It grows up to 15 metres (49 ft) tall, with a trunk diameter of up to 30 centimetres (12 in). Its fragrant flowers feature white, creamy or pale yellow corolla lobes. Fruit consists of 2 separate ovoid or ellipsoid pods, up to 8 centimetres (3.1 in) each.

Range[edit]

Habitat is in forests or bushland from sea-level to 1,000 metres (3,300 ft) altitude. The plant is native to Somalia, Kenya, Tanzania, Mozambique, Zimbabwe, Swaziland and South Africa.[2][3][4]

Uses[edit]

Its numerous local medicinal uses include the treatment of heart disease, cancer, tuberculosis and venereal diseases. T. elegans is also used as an aphrodisiac.[2] The Zulu name for this genus, iNomfi, refers to the use of their sticky, milky latex as bird-lime.[5]

Chemistry[edit]

Fourteen indole alkaloids have been isolated in the callus culture of Tabernaemontana elegans (isovoacangine, 3-R/S-hydroxy-isovoacangine, 3-R/S-hydroxy-coronaridine, isositsirikine, geissoschizol, tabernaemontanine, vobasine, vobasinol, apparicine, 16-hydroxy-16,22-dihydro-apparicine, tubotaiwine, 3-R/S-hydroxy-conodurine and monogagaine) of which apparicine is the principal.[6]
