    In our continuing search for biologically active natural product(s) of plant origin, Buddleja saligna, a South African medicinal plant, was screened in line with its traditional use for antidiabetic (yeast alpha glucosidase inhibitory) and antiplasmodial (against a chloroquine sensitive strain of Plasmodium falciparum (NF54)) activities. The hexane fraction showed the most promising activity with regards to its antidiabetic (IC50=260 +/- 0.112 mu g/ml) and antiplasmodial (IC50=8.5 +/- 1.6 mu g/ml) activities. Using activity guided fractionation three known terpenoids (betulonic acid, betulone and spinasterol) were isolated from this species for the first time. The compounds displayed varying levels of biological activities (antidiabetic: 27.31 mu g/ml >= C-50 >= 5.6 mu g/ml; antiplasmodial: 14 mu g/ml >= C-50 >= 2 mu g/ml) with very minimal toxicity.
