Se presenta una discusión de los espectros de masas de warifteina y metilwarifteina, dos alcaloides bis-benzil- isoquinollnicos aislados de Cissampelos pareira, una especie de importancia etnobotánica. Se da información sobre las posiciones relativas de dos grupos hidroxilo y dos metilos en warifteina, así como sobre la presencia de una parte p-xilílica en la molécula de ambos compuestos.
The mass spectra of the tertiary bis-benzyl-isoquinoline alkaloids, warifteine and methyl-warifteine, extracted from the ethnobotanically important species, Cissampelos pareira L.. are discussed. Infonnation about the reltive positions of two hydroxyl and two methoxyl groups in warifteine and the presence of a p-xylyl moiety in both compounds in provided.
