Resumo: A new triterpene, 3beta,6beta,21beta-trihydroxyolean-12-ene and a new iridoid, 8alpha-methyl-8beta-hydroxy-6beta-(3',4'-dimethoxy)benzoyloxy-1 alpha,3alpha-dimethoxy-octahydro-cyclopenta[c]pyran were isolated from the trunk bark of a specimen of Tabebuia heptaphylla (Bignoniaceae) collected in the "Pantanal" of Mato Grosso do Sul, Brazil. Twelve known compounds were also obtained in this work, comprising four iridoids, 6-O-p-hydroxybenzoylajugol, 6-O-p-methoxybenzoylajugol, 6-O-3",4"-dimethoxybenzoylajugol, 8alpha-methyl-8beta-hydroxy-6beta-(4'-hydroxy)benzoyloxy-1alpha,3 alpha-dimethoxy-octahydro-cyclopenta[c]pyran, a cyclopentene dialdehyde, 2-formyl-5-(3',4'-dimethoxybenzoyloxy)-3-methyl-2-cyclopentene-1-acetaldehyde, a phenylethanoid glycoside, verbascoside and three benzoic acid derivatives, p-hydroxybenzoic, p-methoxybenzoic and 3,4-dimethoxybenzoic acids, in addition to squalene, sitostenone and sitosterol. The antioxidant properties of the isolated compounds were also evaluated in this work.
