Alkaloids as taxonomic markers in some species of Magnolia L. and Liriodendron L.

Mirosław Furmanowa, Joanna Józefowicz

Abstract


Some Magnoliaceae cultivated in Poland were investigated: Liriodendron tulipifera L. and 6 species of magnolia: Magnolia acuminata L., M. denudata Desr., M. kobus DC., M. obovata Thunb., M. salicifolia Maxim. and M. tripetala L. For alkaloid detection in the leaves thin-,layer chromatography was used. In Liriodendron tulipifera L. and in all the Magnolia species liriodenine which exhibits cytostatic activity was detected. The extract of Liriodendron tulipifera L. leaves showed, beside liriodenine other spots on the chromatogram than did the magnolias. Alkaloids can be utilized in the chemotaxonomy of Magnoliaceae as a diagnostic trait. The results of the investigations indicate a certain distinctiveness of M. acuminata L., in agreement with those obtained by way of numerical taxonomy. Most similar as regards alkaloid content in leaves are M. obovata Thunb. and M. tripetala L.
