English abstract | A new oleanane-type triterpene (3beta,6beta,23,28-tetrahydroxyolean-12-ene) was isolated from the leaves of Terminalia glabrescens, together with ursolic, 2alpha-hydroxyursolic, oleanolic, maslinic, arjunolic, sumaresinolic and asiatic acids, squalene, phytol, sitosterol-3-O-beta-D-glucopyranoside and n-alkanes. Friedelin, taraxerol, lupeol, lupenone, betulin, betulone, betulinic acid, arjunglucoside I, stigmastane-3beta,6alpha-diol, beta-sitosterol, (-) catechin,beta-D-pyranotagatose, beta-D-furanofructose and alpha-D-furanofructose were obtained from the trunk bark |

Da casca do caule foram obtidos friedelina, taraxerol, lupeol, lupenona, betulina, betulona, ácido betulínico, arjunglucosídeo I, estigmastano-3beta,6alfa-diol, beta-sitosterol, (-) catequina, beta-D-piranotagatose, beta-D-furanofrutose e alfa-D-furanofrutose |
