he aim of this work was to perform a detailed study of the alkaloid content of Narcissus triandrus, as well as a complete analysis of the alkaloid profile of 18 wild populations, comprising all the taxa of the section Ganymedes. Through the application of a combination of spectroscopic and chromatographic methods, the isolation and structural elucidation of 3 compounds are reported for the first time from a natural source (2-oxomesembrenone, 7,7a-dehydromesembrenone and 2-oxoepimesembranol), together with the identification of 5 major common mesembrane alkaloids. Additionally, the GC-MS analysis of the alkaloid profile demonstrated the regular presence of mesembranes in all the studied plants, showing mesembrenone as the predominant compound without any typical Amaryllidaceae alkaloid being detected.
