Screening of volatiles of Allium tripedale Trautv. and evaluation of the biological activities of its methanol extract

In this report, the volatile profiles from the flowers, leaves, stems and roots of Allium tripedale Trautv. have been characterized using headspace solid phase microextraction (HS-SPME) coupled to gas chromatography-mass spectrometry (GC/MS). Accordingly, high quantities of non-terpene hydrocarbons have been identified as the major constituting groups of all the relevant chemical profiles. The impact of the experimental variables has also been optimized using Design-Expert software. In addition, antioxidant and antibacterial properties of the methanol extract of the plant material have been determined. The results of this study revealed that this plant can be considered a potent antioxidant and antibacterial agent, serving as an alternative to chemical drugs.
