Popis: Leishmaniasis is a neglected tropical disease caused by Leishmania parasitic protozoa, which currently lacks efficient treatment. Natural products have shown promise as a potential source for antiprotozoal drugs. This work focuses on the antileishmanial potential of Sassafras albidum (Lauraceae) bark extract. The crude bark extract of S. albidum showed excellent antileishmanial activity with an IC50 value less than 12.5 μg/mL against promastigotes of L. amazonensis. The chloroform stem bark extract of S. albidum was subjected to preparative column chromatography. Five compounds were isolated, purified by recrystallization, and identified as sesamin, spinescin, β-sitosterol, hexatriacontanal, and 1-triacontanol. Antileishmanial and cytotoxic screening were performed on these compounds. Sesamin exhibited the best activity against L. amazonensis with an IC50 of 15.8 μg/mL and was not cytotoxic to mouse macrophage cells ( CC50 > 100 μg/mL).
