In this study contents of total phenolics and condensed tannins in mature leaves of Anthemideae species from 5 genera different, namely, Anthemis L., Achillea L., Tanacetum L., Tripleurospermum SCHULTZ BIP. and Artemisia L. collected from northeast Anatolia (Turkey) were studied. The highest contents of total phenolics and condensed tannins were found in leaves of Tanacetum coccineum ssp. chamaemellifolium (SOMMIER & LEVIER) GRIERSON (21.7 mg phenol eq/g dry wt) and T. sorbifolium (BOISS.) GRIERSON (159.3 mg phenol eq/g dry wt). Total phenolics content varied significantly (P = 0.01) among the species Tanacetum sorbifolium, T. coccineum ssp. chamaemellifolium, T. nitens (BOISS. & NOE) GRIERSON, T argyrophyllum (C. KOCH) TZVELEV, Tripleurospermum oreades (BOISS.) RECH. var. oreades and T. oreades var. tchihatchewii (BOISS.) E. HOSSAIN. With regard to condensed tannins, the contents varied significantly (P = 0.01) in most of the studied Anthemideae species. Approximately, 33.3% of the studied species differed in total phenolic contents while all the species differed in condensed tannins content apparently due to their taxonomical relationships.
