Flavonoids of Sorghum

Abstract

SUMMARY Three anthocyanogen‐type flavonoids–chromogens I, II, III‐were found by chromatography of a methanol extract of sorghum. Hydrolysis by boiling with acid yielded the same two flavonoids for each of the three chromogens. One was a flavanone, probably eriodictyol; the other was an anthocyanidin‐pelargonidin.
