Yellow Fluorescent Stress Compounds, Pratenols A and B, from Red Clover (Trifolium pratense) Infected by Kabatiella caulivora

Abstract

Two yellow fluorescent compounds, pratenols A (1) and B(2), were isolated from the aerial parts of red clover (Trifolium pratense) infected by the fungus Kabatiella caulivora. The structure of each was established by chemical and spectroscopic methods.
