Determination of PAHs Concentration in Some Types of Phoenix Dactylifera L. Samples from Al-Diwaniyah Markets by Using Soxhlet and Gas Chromatography-Mass Spectroscopy Technique

Objectives: Bioactive components determined by plants are known to have a broad application in the medical field. The focus of this study is to recognize the phytochemicals in the ethanol extract of Brassica oleracea by gas chromatography–mass spectroscopy (GC–MS). Methods: B. oleracea was collected, dried, and powdered well. The extraction was done with the solvent ethanol. The extract was exposed to column of GC-MS-QP 2010 (SHIMADZU) column Db 30.0 (0.25 μm in diameter, 0.25 μm thick). Results: GC–MS result provides the chromatogram with different peaks obtained at a different retention time shows the presence of various biocompounds. Some of the identified bioactive compounds are n-hexadecanoic acid (12.99%), phytol (2.40%), Vitamin E (3.38%), tetratetracontane (2.15%), stigmasterol (2.03%), and isophytol. Conclusion: The GC–MS study of the ethanol extract of B. oleracea reveals the existence of many potential compounds that can be utilized in the pharmaceutical industry, including the use of anti-inflammatory, antiarthritic, anticoronary, and antidiabetic agents.

Gas Chromatography Mass Spectroscopy

Autoxidation products alpha-farnesene of have been implicated in superficial scald induction for apple (Malus domestica cv. Cortland Apple) fruit. We suspect the apple cuticle acts as a sink where α-farnesene can accumulate and eventually autoxidize into hydroperoxides, conjugated trienes, 6-methyl-5-hepten-2-one (ketone), and other compounds. These oxidized byproducts may diffuse back into the peel, thereby initiating the scald process. Cortland apples were stored at 0.8°C. Volatile cuticular components were analyzed at 2-week intervals by gas chromatography–mass spectroscopy. Only two scald-related volatiles were found, 6-methyl-5-hepten-2-one and α-farnesene. The identification of these compounds may allow the determination of cuticular involvement in superficial scald, as well as a possible correlation between the volatiles and apple scald development. α-farnesene concentrations initially increased and was followed by a decline, possibly due to its autoxidation.
