A new lupane triterpene, divergioic acid, has been isolated from the stem bark of Vochysia divergens together with beta-sitosterol, betulinic, sericic and 24-hydroxytormentic acids and the (28 -> 1) beta-D-glucopyranosyl ester of the latter. The structure of divergioic acid was elucidated by spectroscopic techniques and characterized as 2alpha,3beta,6beta-trihydroxy-lup-20(29)-en-28-oic acid.Um novo triterpeno lupânico, ácido divergióico, além de beta-sitosterol, ácidos betulínico, serícico e 24-hidroxitormêntico, e o éster (28 -> 1) beta-D-glucopiranosílico do último, foram obtidos a partir da casca do caule de Vochysia divergens. A estrutura do ácido divergióico foi elucidada por meio de técnicas espectroscópicas, e caracterizada como sen...
