Abstract
Galanthamine is an Amaryllidaceae-type alkaloid with acetylcholinesterase inhibitory
activity which is used in the treatment of Alzheimer’s disease. The distribution of
galanthamine and four other alkaloids in different organs of Narcissus confusus plants, as well as the variations occurring during the ontogenic cycle of this plant
species, was studied. The five alkaloids were found to be present in all the organs
at every stage, with the exception of haemanthamine in senescent flowers. The highest
amount of alkaloids occurred in the bulb at the emerging stage, galanthamine being
the most abundant, reaching a concentration of up to 2.5 % referred to dry weight.
