Medicagol, a New Coumestan From Alfalfa.[Reference:
WebLink]
METHODS AND RESULTS:
A new coumestan, Medicagol(C16H8O6), has been identified in alfalfa. Characterization was accomplished by degradative and proton magnetic resonance (p.m.r.) studies.
CONCLUSIONS:
Synthesis confirmed the structure as 7-hydroxy-11,12-methyl-enedioxycoumestan, closely related to the antifungal agent, pisatin.
