Evaluation of phenolic compounds in several species of some genera of the tribe (Poeae)‎ in Iraq and their taxonomic significance

الملخص EN

Since every taxonomist is aware of the fact that morphological similarities and differences of plants does not always indicate close relationship or often belongs to different taxa.

High-performance liquid chromatography (HPLC) method has been used for the examination of ten species of five genera of the tribe Poeae which is (Cutandia dichotoma, Cutandia memphetica, Dactylis glomerata, Echinaria capitata, Eremopoa persica, Poa angustifolia, Poa annua, Poa pratensis, Poa triviales and Psilurus incurvus) ; eight compounds were isolated and identified.

The results showed variation in compounds concentration, most species are similar in Phenolic compound composition except Cutandia dichotoma, Eremopoa persica and Poa pratensis which are lacking one or more compounds.

The aim of this study is to clarify and improve that these species have the same ancestor and belong to the same family (Poaceae) and tribe (Poeae) in Iraq, depending on the standard values available in the white field company for chemical and engineering consulting in Baghdad.
