Ultraperformance Liquid Chromatography Tandem Mass Spectrometry Determination of Cyanogenic Glucosides in Trifolium Species
journal contribution
posted on 2014-02-26, 00:00 authored by Tamar Muzashvili, Barbara Moniuszko-Szajwaj, Lukasz Pecio, Wieslaw Oleszek, Anna StochmalCyanogenic glucosides
were analyzed by ultra-high-performance liquid
chromatography combined with mass spectrometry in 88 Trifolium species grown at the same site. On the basis of the occurrence of
cyanogenic glucosides and the linamarin/lotaustralin ratio species
could be grouped into five clusters. Cluster C1 included 37 species,
which did not contain cyanogens. Cluster C2 (22 species) included
plants containing only lotaustralin. In clusters C3 (14 species),
C4 (13 species), and C5 (2 species) both linamarin and lotaustralin
were present but at different ratios. In C3 and C4 the linamarin/lotaustralin
ratio was below 1, whereas in cluster C5 the ratio was much higher.
Generally, the total content of cyanogens was below 500 μg/g
dry matter. Only in Trifolium repens var. biasoletti and Trifolium montanum extremely
high cyanogen concentrations were observed. There was no general rule
of occurrence of cyanogens. Samples of the same species from different
countries accumulated cyanogens or could be free of these compounds.
