Lycopodium alkaloids from Palhinhaea cernua

Abstract

Dois novos alcaloides tipo-licopódio, acetil-licoposerramina M e palcernina A foram isolados de extratos de plantas inteiras de Palhinhaea cernua L. juntamente com dez compostos previamente identificados. As estruturas dos dois novos compostos foram elucidadas por métodos espectroscópicos e difratometria de Raios X de monocristal usando o parâmetro Flack.Two new Lycopodium alkaloids, acetyllycoposerramine M and palcernine A were isolated from whole plant extracts of Palhinhaea cernua L. together with ten previously identified compounds. The structures of the new compounds were elucidated by spectroscopic methods and single-crystal X-ray diffraction analyses using the Flack parameter.
