Abstract
Artabotrys crassifolius Hook. f. & Thomson is a medicinal plant used in Malaysia. The cytotoxic effects of the hexane, chloroform and ethanol extracts of the leaves and bark were examined in vitro against MCF-7, MDA-468 and HCT-116 cells. The chloroform extract of the bark inhibited the growth of all cell lines with GI50 values ranging from 4.2 μg/mL to 9.4 μg/mL. Silica gel column chromatography of this extract yielded artabotrine, liridine, atherospermidine and lysicamine. Artabotrine and lysicamine inhibited the growth of HCT-116 and MCF-7 cells with GI50 values ranging from 3.3 μM to 3.9 μM. These alkaloids were not toxic to human embryonic kidney cells (HEK297) up to a concentration of 50 μg/mL.
