- | "The populations of Galanthus differed in their alkaloid biosynthetic pathways. Thus, the alkaloid pattern of G. nivalis was dominated by compounds coming from a para–para′ oxidative coupling of O-methylnorbelladine. The predominant alkaloids in the roots of this species were found to belong to the lycorine and tazettine structural types; bulbs were dominated by tazettine, leaves by lycorine and flowers by haemanthamine type alkaloids. In contrast, the alkaloid pattern of G. elwesii was dominated mainly by compounds coming from an ortho–para′ oxidative coupling." | + | "The populations of Galanthus differed in their alkaloid biosynthetic pathways.
