Ergosine ergosinine and chanoclavine i from epichloe typhina

, : Ergosine ergosinine and chanoclavine i from epichloe typhina. Journal of Agricultural & Food Chemistry 27(3): 595-598

E. typhina, isolated from toxic K-31 tall fescue grass [Festuca arundinacea], produced ergot alkaloids in vitro. Ergosine, ergosinine and chanoclavine I were isolated and identified by comparison with authentic standards regarding TLC, UV absorption and low-resolution mass spectra analyses. Total alkaloid production, colorimetrically determined as ergonovine maleate, was 5.5 mg/l for 28 day old cultures. This is the 1st report of a fungus outside the genera of Claviceps and Balansia capable of producing alkaloids that are N-peptide-substituted amides of lysergic acid.
