Chemical Constituent

T. corymbosa  has been reported to contain 3R/S-ethoxyheyneanine, 3R/S-ethoxy-19-epi-heyneanine, 7(R)- geissoschizol oxindole, 7(S)-geissoschizol oxindole, 7(R),16(R)- 19(E)-isositsirikine oxindole, 7(S),16(R)-19(E)-isositsirikine oxindole, 19'(S)-hydroxyconodurine, 19'(S)-hydroxyconoduramine, 19'(S)-hydroxyervahanine A, 19(S)-hydroxyibogamine, 19-epi-isovoacristine, 19’(S) hydroconoduramin, 19’(S)-hydroxyyervahanine A, N(4)-demethyltaberpsychine,  conodiparines A-F, conodurine, conodurinine, conodutarines A and B, cononitarines A and B, ervahanine A, isovoacryptine, jerantinine A – H, jerantiphyllines A and B, tabersonine hydroxyindolenine, and vincamine. [6][7][8][9][10][11][12][13]

Plant Part Used

Bark, leaves, and roots. [6]

Traditional Use

In China, the bark and leaves are used for the treatment of fractures. The roots are used in Malaysia to recover from childbirth and exhaustion, and a paste of the plant is used to treat orchitis. [6][14]

The plant is used in the treatment of ulceration of the nose in tertiary syphilis (restung). [14]

Preclinical Data


Cytotoxic activity

Five alkaloids (jerantinines A-E) isolated from T. corymbosa showed pronounced in vitro cytotoxicity against human KB cells (IC50<1µg/mL). Conodiparines showed significant activity in reversing resistance in vincristine-resistant KB cells. [9][13]
