Abstract

WE reported in our previous notes1 on the vitamin nature of phenyl-benzo--pyrone dyes, and have described a method for the experimental demonstration of this activity. Using this method, we tested the following substances for their vitamin activity: hesperidine (m.p. 261°), an impure sample of demethylo-hesperidine (mother liquor of citrin) and quercitrine, 1 mgm. being given daily.
