Abstract:
Três novos derivados de 8-O-4'-neolignanas, fargesifenols A-C, juntamente com seis neolignanas conhecidas, foram isoladas de botões de flores de Magnolia fargesii. As estruturas foram elucidadas por métodos espectroscópicos, incluindo técnicas de RMN 1D e 2D. Os compostos foram também testados quanto à sua atividade anti-HIV-1 e quanto às citotoxicidades.Three new 8-O-4'-neolignans, fargesiphenols A-C, together with six known neolignans, were isolated from the flower buds of Magnolia fargesii.
