Summary
Galanthamine, a key alkaloid, was detected in two Bulgarian populations of Galanthus elwesii. This study investigated alkaloids in Galanthus elwesii and Galanthus nivalis using chromatography and mass spectrometry.
Area of Science:
- Pharmacognosy
- Botany
- Analytical Chemistry
Background:
- Galanthus elwesii and Galanthus nivalis are Bulgarian native species.
- Galanthamine is a valuable alkaloid with medicinal applications.
- Previous research on Bulgarian populations of these species is limited.
Purpose of the Study:
- To investigate the presence and distribution of galanthamine in Bulgarian populations of Galanthus elwesii and Galanthus nivalis.
- To analyze the alkaloid profiles of these species using advanced analytical techniques.
Main Methods:
- Thin-Layer Chromatography (TLC) for initial alkaloid screening.
- Gas Chromatography-Mass Spectrometry (GC-MS) for precise identification and quantification.
- Sampling of sixteen populations of G. elwesii and five populations of G. nivalis across Bulgaria.
Main Results:
- Alkaloids were detected in all investigated populations, with 3 to 11 alkaloids identified per sample.
- Galanthamine was specifically identified in two out of the sixteen studied populations of G. elwesii.
- No galanthamine was detected in the investigated populations of G. nivalis.
Conclusions:
- Bulgarian populations of Galanthus elwesii show potential as a source for galanthamine extraction.
- Further research is warranted to explore the ecological and genetic factors influencing galanthamine content in G. elwesii.
- The findings contribute to the understanding of alkaloid diversity in Bulgarian native flora.
