euodia madagascariensis/leukemia

Nine indoloquinazoline alkaloids (1-9) were isolated from the dried and nearly ripe fruits of Euodia rutaecarpa (Juss.) Benth. (Euodiae Fructus), along with limonin and β-sitosterol. Their structures were elucidated on the basis of their spectroscopic data. Among them, compounds 1 and 2 were new

Four quinolone alkaloids (1-4) and three indole alkaloids (20-22), together with 30 known alkaloids (5-19, 23-37), were isolated from the fruits of Euodia rutaecarpa. Their structures were established by spectroscopic analyses. The in vitro cytotoxic activities of these alkaloids against leukaemia
