Aqueous acetone extracts of leaves from ten browse plants were examined by high performance liquid chromatography and thin layer chromatography for their phenolic constituents. Flavan‐3‐ols, flavonols and flavonol glycosides were characterised and identified together with gallic, ellagic and chlorogenic acids. Condensed and hydrolysable tannins were also detected. Trans‐and cis‐p‐coumaric and trans‐ferulic acids were identified after alkaline hydrolysis of the browse leaves. The content of these acids was high in plants with the lowest tannin contents.
