The present study was carried out to investigate the chemical composition of the alcoholic thuja and oranges peels extract using Gas Chromatography – Mass Spectrometry (GC-Ms). Fifty-five compounds were determined for Thuja leaves extract, most notably the D-Limonne, Ferrgoinol, and Terpine-4-IL, which are known as its antioxidant and microbial properties. In the orange peel extract, it was determined 78 compounds, including nootkatone, Squalene and D-Limonne, known as its role in the pharmaceutical industries and cosmetics. The current study analyzes indicated that the use of methanol alcohol in the Soxhlet system increased the efficiency of extracting semi -polar compounds such as phenols and glycosides and flavonoids. The current study also emphasized the sensitivity of the GC-MS technology in detecting volatile and non-polar compounds, such as D-Limonne, which appeared in both extractors. The study emphasized the importance of choosing the technique of extraction and the type of solvent in enhancing the efficiency and quality of the extracted vehicles. the present study also offers a valuable chemical database for the optimal exploitation of these plants in the medical, agricultural, and industrial fields, in line with the principles of environmental sustainability.
