Chemical composition

Multiple compounds of different classes such as Iboga alkaloids and Bisindole alkaloids have been isolated from this plant. Alkaloids such as conodusine A-E, conolodinines A-D, conophylline, conophyllinine and taberyunines A-I are present in which many shows antiproliferative and cytotoxic actions.[2][3][4][5]
