the activity. A bioguided fractionation of Manilkara rufula was performed and four major compounds were identified: caproate of α-amyrin (1b), acetate of β-amyrin (2a), caproate of β-amyrin (2b), and acetate of lupeol (3a). In addition, six derivatives of α-amyrin (1), β-amyrin (2) and lupeol (3) were synthesized and tested against the parasite. Ursolic acid (5) reduced about 98% of parasite viability
