The cytotoxicity of crude alkaloid extracts obtained from the
leaves and rhizomes of all the South African members of the
family Menispermaceae (seven genera and 13 species) was
tested against MCF7 (breast), UACC62 (melanoma) and TK10
(renal) cancer cell lines. Extracts of ten of the thirteen
species showed positive activity against all three cancer
cell lines with
significant inhibition of cellular growth at TGI
(total
growth inhibition)
values lower than 6.25 μg/ml for Albertisia delagoensis
and Antizoma angustifolia leaves.
