Phytochemical Profile of Urtica dioica L. by Gas Chromatography-Mass Spectrometry GC-MS and Antioxidant Activity

Leaves are rich in many phytochemical compounds, all bioactive compounds formed normally during plants metabolism as  secondary  products. The  phytochemical compounds  screened by gas chromatography-mass spectrometry (GC-MS) method. Twenty nine  bioactive phytochemical compounds  were  identified  in  the  .  The  GC-MS  analysis  of  U. dioica  revealed  the  identification  of phytochemical  compounds  is  based  on  the  peak  area,  retention  time  ., as well as the antioxidant activities of the leaves were determine. . the first compound was benzene that presence at 5.339 min with peak  area 1.18, while the 9-Octadecenamide was the last compound shown at 68.304 min with 2.18 peak area. Including  organic compounds, fatty acids and phenols.  A DPPH radical scavenging e results showed U. dioica extract at 600 concentrations high than ascorbic acid was93.76 µg/ml while aceorbic acid was 91.14 µg/ml. this finding indicate that U. dioica have high antioxidant ability.  . This  manuscript to cover  the  chemical  composition  of  methanolic  extract  of  U.  dioica leaves  ( stinging nettile)  that growing naturally in Iraq, as a chemical study and provide details of pharmacological propos
