This study was carried out in the laboratory of college of agriculture and forestry to identifying the phenolic compounds for twenty kinds of plants used in plant identification, The crude lipid free extract was prepared by using soxhlet and Petroleum ether and Ethanol as a solvent, Thin layer technique was used for determine phenolic compounds in the extract.

The results showed the isolation of 27 phenol compounds including Salicylic acid, Vanillin, Catechol, Gallic acid, p–Hydroxybenzoic acid Resorcenol, Coumarin, Phenol, Cinnamic acid, Rutin, Quercetin, Kaempferol, Hydroquinone, Syringic acid, Ellagic acid, Myricetin, Apigenin, Ferulic acid, Lutelen, Catiechin, Afzelechin, Epiafzelechin) Esuliten, Apicathichin, Gallocatechin, Herniaren, Thymol )phenolic compounds between the species, Salicylic acid was the purulent.

The results were showed many differences in the number and rates of Salicylic acid, Vanillin, Catechol, Gallic acid, p – Hydroxybenzoic acid Resorcenol,, Coumarin, Phenol, Cinnamic acid, Rutin, Quercetin, Kaempferol, Hydroquinone, Syringic acid, Ellagic acid, Myricetin, Apigenin, Ferulic acid, Lutelen, Catiechin, Afzelechin, Epiafzelechin) ,Esuliten, Apicathichin, Gallocatechin, Herniaren, Thymol) The result showed many differences in phenolic compounds in the Genus and between the species and semelirty of species in same Genus in some of phenolic compounds (Salicylic acid, Quercetin) were the purulent in Fabaceae family (Trifolium, Onobrychis) Genus, also the result showed differences between (Hordeum bulbosum, H.

glaucum) in Poaceae family,some differences showed between (Quercus aegilops, Q.

infectoria) in Fagaceae family, the result appeared many differences in kind and number and percentage of phenolic compounds between species in chemical compounds could be used as an indicator for plant identification
