This paper uses LC/MS technology to analyze the crude extract of ergot fungus, identify and characterize its ergot alkaloid content. Alkaloids possessing a lysergic acid structure were identified with a nano LC/MS ion trap system and purified using mass based fraction collection. The purified alkaloids were then structurally characterized with MSn experiments. Several well-known ertgot alkaloids were identified and several so far unknowns were determined and structurally characterized using MSn.
