6-acetonyl-N-methyl-dihydrodecarine, a new alkaloid from Zanthoxylum riedelianum (original) (raw)

2009, Journal of the Brazilian Chemical Society

Um novo alcalóide benzofenantridínico, 6-acetonil-N-metil-diidrodecarina foi isolado das raízes de Zanthoxylum riedelianum juntamente com lupeol, 6-acetonildiidroqueleritrina e 6-acetonildiidroavicina. As estruturas dessas substâncias foram estabelecidas com base na análise dos dados espectrométricos de IV, EM e RMN incluindo experimentos 2D. A new benzophenanthridine alkaloid, 6-acetonyl-N-methyl-dihydrodecarine was isolated from Zanthoxylum riedelianum roots together with lupeol, 6-acetonyldihydrochelerythrine and 6-acetonyldihydroavicine. The structures were established from the IR, MS and NMR spectral data, including 2D-NMR experiments.
