Abstract
3:7:2'-5'-Tetrahydroxy flavone and 3:5:7:2':5'-pentahydroxy flavone and their derivatives are prepared and their colour reactions recorded. The flavone with only 2'-hydroxyl free (X) and also its 5'-hydroxyl derivative (XI) do not give any colour with ferric chloride indicating absence of chelation. Alkali colour reactions confirm the original finding that a quinol grouping in the side phenyl nucleus does not produce marked colour effects.
