The Chemistry of Eucalypt Kinos. II. Aromadendrin, Kaempferol, and Ellagic Acid

Abstract

Aromadendrin has been isolated in about 5 per cent. yield from the kino of Eucalyptus calophylla and in 1.1-1.3 per cent. yield from the kino of E. corymbosa. It has been identified as 3,4',5,7-tetrahydroxyflavanone. Kaempferol was isolated from E. calophylla kino and ellagic acid from both kinos.
