Chemical composition and antiradical capacity of essential oils from Lebanese medicinal plants / M. Iriti, S. Vitalini, N. Arnold Apostolides, M. El Beyrouthy. - In: JOURNAL OF ESSENTIAL OIL RESEARCH. - ISSN 1041-2905. - 26:6(2014), pp. 466-472. [10.1080/10412905.2014.947388]
Abstract:
Essential oils from five wild species growing in Lebanon and used in traditional medicine were obtained by hydrodistillation. Their chemical composition was determined by gas chromatography (GC) and GC-mass spectrometry (GC-MS), and the major constituents were α-pinene in Juniperus excelsa M. Bieb. (68.8-86.8%, according to different organs), carvacrol in Thymbra spicata L. (65.8%) and Coridothymus capitatus (L.) Rchb. f. (47%), pulegone in Mentha spicata L. subsp. condensata (Briq.) Greuter & Burdet (32.8%) and 1,8-cineole in Salvia fruticosa (Mill.) K. Schum. (48.7%). Antiradical capacity of the essential oils was measured in vitro by the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTSs+) radical cation and 2,2-diphenyl-picryl hydrazyl (DPPHs) radical assays. A good agreement between the two tests was recorded: C. capitatus and T. spicata oils showed the highest ABTSs+ and DPPHs radical-scavenging activity, possibly due to their high levels of carvacrol, whereas the lowest antiradical capacity was reported for J. excelsa oils.
