Analyses of selected endophyte-infected grasses for the presence of loline-type and ergot-type alkaloids

Selected endophyte-free and endophyte-infected grasses from the genera Festuca, Lolium, Hordeum, Stipa, and Poa were analyzed for the presence of loline- and ergot-type alkaloids. Loline alkaloids were analyzed by capillary GC, and ergot-type alkaloids were analyzed by reversed-phase HPLC. None of t...

Zusammenfassung:	Selected endophyte-free and endophyte-infected grasses from the genera Festuca, Lolium, Hordeum, Stipa, and Poa were analyzed for the presence of loline- and ergot-type alkaloids. Loline alkaloids were analyzed by capillary GC, and ergot-type alkaloids were analyzed by reversed-phase HPLC. None of the endophyte-free samples contained detectable levels of either of these alkaloid types. Endophyte-infected grass samples gave widely variable alkaloid concentrations. N-Formylloline was the predominant loline alkaloid, and ergovaline was usually the predominant ergot-type alkaloid in these samples
