Abstract

IT was suggested in an earlier note1 that the flavone isolated from lucerne which, like most flavones, inhibits smooth-muscle movements, was 3′,4′,5-trihydroxy-7-methoxyflavone. Further work on larger quantities of the flavone purified by high-vacuum sublimation has now shown it to be tricin, 5,7,4′-trihydroxy-3′,5′-dimethoxyflavone, a flavone found in Triticum dicoccum2.
