Abstract:
The present study reported for the first time from Iraq about some detailed information on chemical composition of the study examined the precise properties of the chemical content of some Cyperaceae family, which included the Cypress L. species. Five species were observed, three of which were chemically analyzed: C.difformis, C.odoratus and C.alternifolius. The samples were collected from the Riverside of the Diwaniyah River and specifically (Sunni area, Daghara area, Diwaniyah district) during the autumn and winter season from 15/10/2016 to 15/3/2017. The chemical content of leaves, which was characterized by its abundance in species under study, the chemical compounds were identified using Gas chromatography-mass spectrometry (GC-MS). The richness of the species under study in secondary metabolites, which ranged from: terpenes, phenols, steroids, Fatty acids, alkanes, alkaloides and esters. and all phytochemicals of the species participated in 7 compounds like : Hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl)ethyl ester, Octadecanoic acid, 2,3-dihydroxypropyl ester , Phytol , gamma.-Sitosterol and l-(+)-Ascorbic acid 2,6-dihexadecanoate. It was characterized by high concentrations of different species that helped to isolate them clearly from each other, also some species were involved in the same compounds like: Squalene and Campesterol. Also distinguished and separated from each other by other compounds such as: Caryophyllene oxide and Phenol, 2,3,5,6-tetramethyl. Which reinforced the taxonomic importance of this study, so this study is of great importance. In the current study, two species were recorded for the first time on the river: C.odoratus and C.alternifolius.
