Galanthus nivalis L. - syn.Galanthus imperati Bertol. - Amaryllidaceae
(common) snoedrop, (Kleines) Schneeglöckchen

Perennial herb, up to 15cm high, native to South and Central Europe, cultivated (as ornamental) and naturalized elsewhere.

„The plant and its alkaloids are very toxic and not used for self-medication… Dried and powdered bulbs of both species [G.nivalis and G.woronowii] (Galanthis bulbus) are used for alkaloid extraction… The isolated alkaloid, galanthamine, is used to alleviate the symptoms of neuromuscular ailments such as neuritis and neuralgia, as well as myasthenia gravis and polimyelitis…“
[Medicinal Plants of the World. Ben-Erik Van Wyk and Michael Wink, Pretoria 2004, 149]

„Kalashnikov (1970) also reported six alkaloids for G. nivalis L. (galanthamine, nivalidine, narwedine, lycorine, hippeastrine and tazettine). The structure of magnarine, another alkaloid isolated in the 1960s from G. nivalis, is unknown.“
The alcoholic extract from fresh aerial parts and bulbs contained alkaloids like hamayne, lycorine (galanthidine), ungeremine, tazettine and ismine, as well as various derivatives of hamayne and lycorine with hydroxylated butyric acids.

„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.“
