| Spanish abstract | La investigación química de las raíces de R. laevigata condujo al aislamiento de dos nuevos flavonoides, 8-(+)-catequin-ácido acético (1) y éter 4-metílico de guibourtacacidina (2); un flavonoide conocido, guibourtacacidina (3), y siete triterpenos conocidos, ácido euscáfico (4), kajichi-gósido F1 (5), nigaichigósido F2 (6), rubúsido J (7), ácido toméntico (8), rosamutina (9) y ácido betulínico (10). Las estructuras fueron establecidas de acuerdo a las evidencias espectroscópicas y comparaciones con los datos informados en la literatura. Los compuestos 1, 2 y 3 mostraron actividad atrapadora de radicales en el ensayo del 1,1-difenil-2-picrilhidracilo (DFPH) |
| English abstract | Chemical investigation on the root of R. laevigata led the isolation and identification of two new flavonoids, (+)-catechin-8-acetic acid (1) and guibourtacacidine 4-methyl ether (2), one known flavonoid, guibourtacacidine (3), along with seven known triterpenoids, euscaphic acid (4), kajiichigoside F1 (5), nigaichigoside F2 (6), rubuside J (7), tomentic acid (8), rosamutin (9) and betulinic acid (10). Their structures were established on the basis of spectroscopic evidence and comparisons with literature data. Compounds 1, 2 and 3 showed considerable radical scavenging activity in the 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay |
