This paper evaluates CHCl 3 and CH 3 OH extracts of the stem bark, branches and leaves of Drimys brasiliensis and drimane sesquiterpenes isolated from the stem bark against strains of Leishmania amazonensis and Leishmania braziliensis promastigotes and Plasmodium falciparum trophozoites.
Another compound evaluated was the aromadendrane spathulenol Figurecompound 1which was isolated from the chloroform extracts. The rutin, catechin, epicatechin, vanillic acid, ferulic acid, p -coumaric acid, and caffeic brasiliensus RS were prepared at a concentration of Only seedlings with roots of 2 mm in length were selected and transferred to transparent plastic boxes 13 x 8 x 3 cm containing filter paper moistened with 5 mL of the negative control solution, leaf or root fractions, or herbicide.
