RESUMO
In the course of the chemical investigation of extracts of the trunk bark and root bark of Trema orientalis, three new compounds were isolated, namely, (9S*,10S*)-3-[7-(3,10-dihydroxy-9-hydroxymethyl-2,5-dimethoxy)-9,10-dihydrophenanthrenyl]propenal (1), (9S*,10S*)-3-[7-(5-O-beta-glucopyranosyl-10-hydroxy-9-hydroxymethyl-2,6-dimethoxy)-9,10-dihydrophenanthrenyl]propenal (2), and (3R*,3aR*,4R*,5S*)-6-O-alpha-arabinopyranosyl-8-hydroxy-3-(4-hydroxyphenyl)-4-(4-hydroxyphenyl)-5-(3,5-dihydroxyphenyl)-3,3a-dihydrocyclopenta[1,2,3-de]isobenzopyran-1-one (3, orientoside A). The structures of 1-3 were determined by spectral methods.
