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.
采用 GC 和 GC/MS 对古巴桃金娘科白千层叶和果实油的植物化学成分进行了研究。鉴定并定量了 41 种和 64 种挥发性化合物，分别占叶油和果油总成分的 99.2%和 99.5%。叶油中的主要成分是 1,8-桉叶素（43.0%）、桃金娘醇（24.2%）、α-松油醇（7.0%）、α-蒎烯（5.3%）和柠檬烯（4.8%），而果油中的主要成分是桃金娘醇（47.6%）、愈创木醇（5.8%）、愈创木薁醇（5.3%）和α-蒎烯（4.5%）。通过三种不同的体外测定法（2,2-二苯基-1-苦基肼基（DPPH）自由基、硫代巴比妥酸反应性物质（TBARS）和 2,2'-联氮双（3-乙基苯并噻唑啉-6-磺酸）（ABTS）自由基阳离子）测定了这些精油的抗氧化能力，所有这些精油都表现出显著的活性。
