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 ...

Abstract:
... Leucojum aestivum, an industrial source of the acetylcholinesterase inhibitor galanthamine, shows a great chemodiversity in its alkaloid synthesis. Samples from various geographically distinct populations from Bulgaria and the Balearic Islands were studied by GC–MS. The alkaloid pattern of the plants of L. aestivum (subsp. pulchellum) from the Balearic Islands were dominated by crinine type compou ...

Abstract:
... Underivatised alkaloid mixtures extracted from intact plants and in vitro cultures of Leucojum aestivum (Amaryllidaceae) were investigated by capillary GC-MS. Excellent peak resolution for the alkaloids was exhibited and isomers of galanthamine and N-formylnorgalanthamine were well separated. Fourteen alkaloids of galanthamine, lycorine and crinane types were identified, 11 in the intact plants an ...

Abstract:
... The characterization Bulgarian natural growing areas of Leucojum aestivum L. was on the basis of the chemical composition of the plants and some soil characteristics which give an opportunity to choose those conditions suitable for growing and obtaining enlargement of the source of plant material with high galanthamine content. This information should benefit the improvement of natural growing are ...

Abstract:
... The elemental composition of seven soils of the main geographical regions in Bulgaria for the growth of Leucojum aestivum L. was determined. It was found that a relationship exists between the galanthamine content of the plant and the chemical composition of the soil. These results indicate that galanthamine bio-synthesis could be controlled by the soil fertility level. ...
