| Abstract | ||
| The present work identified (8) cultivars belonging to the species Pyrus malus L. that included ("EarlyGold", "GrannySmith", "Royal Cala", "Red Delicious", "Golden Delicious", "Honey Crisp", "Mcintosh" and Cox") as well as (6) Cultivars of the species Pyrus communis L. namely ("Coneference", Decana", "Bonica", "Alkhatuni","Alothmani" and "William) by using spectral and chemical characteristics. The spectral study showed that different max appeared among all the cultivars of the species, and the result of chemical study identified (7) phenolic compounds in alcoholic extracts of leaves by using High Performance Liquid Chromatography (HPLC) including (Apigenin, Kaempferol, Catichen, Rutin, Luteolin, Quercetin and Coumarin) using (7) standard compounds for comparison among the cultivars. The compounds Apigenin, Kaempferol, Catichen, Leuteolin and Quercetin found in all cultivars of the species Pyrus communis L. while Rutine, Leuteolin, Quercetin and Coumarin found in all cultivars of the species Pyrus malus L. but Kaempferol compound found only in "Early Gold", "Royal Cala" and "Honey Crisp". The cultivar "EarlyGold" showed that lowest concentration of the compound Rutin (1.13) g/g and highest concentration of the compound Quercetin (685.96) g/g. The spectral and chemical characters showed a good taxonomic value in identification and separation the cultivars of the two species. | ||
