Dibenzylbutane lignans from Virola sebifera leaves

Two new dibenzylbutane lignans, rac-(8a,8′P)-4,4′-dihydroxy-3,3′-dimethoxylignan-9,9′-diyl diacetate and rac- (8a,8′P)-4-hydroxy-3-methoxy-3′,4′-methylenedioxylignan-9,9′-diyl diacetate were isolated from the toluene extract of Virola sebifera leaves, in addition to the previously described lignan,...

Zusammenfassung:Two new dibenzylbutane lignans, rac-(8a,8′P)-4,4′-dihydroxy-3,3′-dimethoxylignan-9,9′-diyl diacetate and rac- (8a,8′P)-4-hydroxy-3-methoxy-3′,4′-methylenedioxylignan-9,9′-diyl diacetate were isolated from the toluene extract of Virola sebifera leaves, in addition to the previously described lignan, (−)-haplomyrfolin. Their structures were established by spectral analysis.
