Abstract
Three quassinoids from the roots of Eurycoma longifolia Jack were evaluated for anti-malarial activity against nine Plasmodium falciparum isolates obtained from patients infected with chloroquine-resistant malaria. The results indicated that eurycomanol, eurycomanol 2-O-β-D-glucopyranoside, and 13β,18-dihydroeurycomanol possessed anti-malarial activity with IC50 values of 1.231 - 4.899 µM, 0.389 - 3.498 µM, and 0.504 - 2.343 µM, respectively, compared with 0.323 - 0.774 µM for chloroquine.
