RESUMO

Iryanthera paraensis e I. tricornis (Myristicaceae) contêm na madeira de seus troncos 1-(2', 4' - dihidroxifenil) -3- (4", 5"-metilenodoxi-2" -metoxifenil) -propano (1a 1-(2', 4' dihidroxifenil) -3-(3", 4" -metilenodioxifenil)-propano (1b) e 1-(4' -hidroxi -2'-metoxifenil) -3-(4"-hidroxi-3"-metoxifenil) -propano (1c). Apenas da primeira espécie se isolou adicionalmente 1-(2', 4'-dihidroxi-3' -metilfenil)-3-(4", 5"-metilenodioxi-2"- metoxifenil) -propano (1d) e 1-(2'-hidroxi-4'metoxifenil) -3-(3", 4"-metilenodioxifenil) -propano (1e). Dados espectroscópicos para a substância 1b, são descritos pela primeira vez.

ABSTRACT

Iryanthera paraensis and I. tricornis (Myristicaceae) both contain in their trunk wood 1-(2' ,4'-dihydroxyphenyl)-3-(2"-methoxy-4", "-methylenedioxyphenyl) -propane (1a),1 -(2',4'-dihydroxyphenyl)-3-(3", 4"-methylenedioxyphenyl)-propane (1b) and 1- (4'-hydroxy -2'-meyhoxyphenyl-3-(4"-hydroxy-3"-methoxyphenyl) -propane (1c). Only from the former species 1- (2' ,4'-dihydroxy-3' -methylphenyl) -3- (2"-methoxy-4",5"-methylenedioxyphenyl) - propane (1d) and 1-(2'-hydroxy-4'-methoxyphenyl)-3-(3",4"-methylenedioxyphenyl)-propane. (1e) were isolated additionally. Data for compound 1b are described for the first time.
