Subject:
Alzheimer disease; Leucojum aestivum; acetylcholinesterase; bulbs; gas chromatography-mass spectrometry; lycorine; summer; Bulgaria
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 ...

Open life sciences 2014 v.9 no.11 pp. 1011-1021
ISSN:

Subject:
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 ...

Subject:
Leucojum aestivum; alkaloids; ammonium nitrate; ammonium sulfate; biosynthesis; potassium dihydrogen phosphate; potassium nitrate; regression analysis; sucrose
Abstract:
... The common effect of NH₄⁺, NO₃⁻, KH₂PO₄ and sucrose on the biosynthesis of galanthamine by a Leucojum aestivum shoot culture was studied. Polynominal regression models were elaborated for the description of the galanthamine biosynthesis as a consequence of variation of the investigated variables (NH₄⁺ between 0.20 and 0.54 g/L; NO₃⁻ between 1.44 and 3.44 g/L; KH₂PO₄ between 0.10 and 0.24 g/L, and ...
