Chromatographic Analysis of Eucalypt Kinos

KINOS are dark cellular accretions or astringent exudations containing phenolic substances. They are commonly seen as vitreous lumps on the bark, or as veins in the timber, of many eucalypts, and are locally known as ‘gums’. The kinos of certain eucalypts have been examined by the Williams and Kirby's solvent ascent modification 1 of the paper partition chromatographic technique 2 .
