Abstract/OtherAbstract:
The phytochemical profile of Melaleuca leucadendra L. leaf and fruit oils from Cuba was investigated by GC and GC/MS. Forty-one and sixty-four volatile compounds were identified and quantified, accounting for 99.2 and 99.5% of the leaf-oil and fruit-oil total composition, respectively. The main components were 1,8-cineol (43.0%), viridiflorol (24.2%), α-terpineol (7.0%), α-pinene (5.3%), and limonene (4.8%) in the leaf oil, and viridiflorol (47.6%), globulol (5.8%), guaiol (5.3%), and α-pinene (4.5%) in the fruit oil. The antioxidant capacity of these essential oils was determined by three different in vitro assays (2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, thiobarbituric acid reactive species (TBARS), and 2,2'-Azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cation), and significant activities were evidenced for all of them.
