Abstract:
... Galanthamine is a natural compound used for the treatment of Alhzeimer’s disease. Currently, it is extracted at industrial scale from Narcissus pseudonarcissus cv. Carlton, Lycoris radiata and Leucojum aestivum. Hippeastrum papilio is an ornamental plant which shows advantages in comparison to the currently used plants for galanthamine extraction. It is a plant without a period of dormancy with bu ...

Abstract:
... Leucojum aestivum (summer snowflake) is a plant species used for the extraction of galanthamine, an acetylcholinesterase inhibitor for the treatment of Alzheimer’s disease. Extracts from bulbs collected from 18 Bulgarian populations and from shoot-clumps obtained in vitro from 8 different populations showed variations in their alkaloid composition. Nineteen alkaloids were detected in the studied s ...

Leucojum aestivum; microscopy; paclobutrazol; survival rate; sucrose; gibberellic acid; acclimation; nuclear genome; bulbs; stomata; roots
Abstract:
... The effects of growth retardants (paclobutrazol and ancymidol), sucrose, GA3 (gibberellic acid) and physical state of the medium (solid and liquid — Rita® temporary immersion system) on in vitro induction of Leucojum aestivum bulbs and their acclimatization were studied. Paclobutrazol, regardless of the physical state of the medium, stimulated the formation of bulbs (99.3%). Under the influence 90 ...

Abstract:
... In vitro cultures of Leucojum aestivum are considered as an alternative for the production of galanthamine, which is used for the symptomatic treatment of Alzheimer’s disease. We studied the effects of auxins 2,4-dichlorophenoxyacetic acid (2,4-D), 4-amino-3,5,6-trichloropicolinic acid (picloram), 3,6-dichloro-o-anisic acid (dicamba) at concentrations of 25 and 50 µM on the induction of embryogeni ...

Abstract:
... Leucojum aestivum L. (Amaryllidaceae) is a polycarpic C-S-European/W-Asiatic geophyte. It is a threatened wetland species and is protected in several European countries, as a consequence of the destruction or alteration of its habitats across Europe and the harvesting of its bulbs for medical purposes (alkaloids). This paper deals with the taxonomic status, morphology, distribution, ecology and po ...
