The chemical compositions have been investigated of the volatile oils of nine populations of six species from Albania, namely Artemisia absinthium, Calamintha nepeta, Hypericum perforatum, Sideritis raeseri subsp. raeseri, Origanum vulgare subsp. hirtum from two wild .populations, and Salvia officinalis (sage) from two wild and one cultivated population,. The essential oils were obtained by hydrodistillation and their analyses were performed by GC-MS. The major constituents were: A. absinthium: neryl isovalerate (19.5%), geranyl isobutanoate (16.4%) and carvacrol (8.8%); C. nepeta: pulegone (31.7%), spathulenol (20.0%) and isomenthone (12.7%); H. perforatum: caryophyllene oxide (31.0%), δ-selinene (10.5%) and carvacrol (10.4%); O. vulgare: carvacrol (81.0, 78.6%), y-terpinene (5.5, 7.1%) and p-cymene (4.9, 4.1%) for 0. vulgare originating from Tepelena. and.Vlora, respectively; S. raeseri: carvacrol (36.7%), caryophyllene oxide (17.8%), p-caryphyllene (8.7%), spathulenol (7.7%) and myrtenol (6.4%); S. officinalis: camphor (40.2, 47.8, 45.9%), c-thujone .(19.2, 22.2, 13.7%), eucalyptol (5.4, 2.6, 6.0%), camphene (5.8, 6.1, 3.9, %), borneol (2.1, 2.9, 5.7%) and bornyl acetate (3.3, 1.4, 5.6%) for samples originating from Tepelena, Tirana and Vlora, respectively. The essential oils were also tested for their free radical scavenging activity using the following in vitro assays: i) interaction with the free stable radical of DPPH (1,1-diphenyl-2-picrylhydrazyl), and ii) inhibition of linoleic acid-peroxidation with 2,2'-azobis- 2-methyl-propanimidamide, dihydrochloride (AAPH). Finally, their inhibitory activity toward soybean lipoxygenase was evaluated, using linoleic acid as substrate.The essential oil of 0. vulgare (OV-VL) presented the highest interaction with the stable radical DPPH (76.5%), followed by that of A. absinthium (54.7%). O. vulgare (OV-TP) and A. absinthium showed high anti-lipid peroxidation activity, 97.5% and 96.5%, respectively, higher than that of the reference compound trolox (73.0%). Only the tested sample of O. vulgare (OV-VL) significantly inhibited soybean lipoxygenase (54.2%).

阿尔巴尼亚一些芳香和药用植物精油的抗氧化活性和化学成分。

对来自阿尔巴尼亚的六个物种的九个种群的挥发油的化学成分进行了研究,这些挥发油是苦艾,景天,贯叶连翘,蜘蛛五味子亚种。牛至,牛至子亚种。来自两个野生种群的hirhir,和来自两个野生种群和一个栽培种群的鼠尾草(鼠尾草)。通过加氢蒸馏获得精油,并通过GC-MS进行分析。主要成分为:A.苦艾酒:异戊酸橙基酯(19.5%),异丁酸香叶基酯(16.4%)和香芹酚(8.8%);荆芥(C. nepeta):鼠薄荷(31.7%),芦丁烯醇(20.0%)和异薄荷酮(12.7%); 贯叶连翘:石竹烯氧化物(31.0%),δ-辛烯(10.5%)和香芹酚(10.4%);普通麦(O. vulgare):香芹酚(81.0,78.6%),γ-萜品烯(5.5,7.1%)和对伞花烯(4.9,4.1%)为0。源自Tepelena的粗俗。和.Vlora,分别;葡萄球菌:香芹酚(36.7%),石竹烯氧化物(17.8%),对叶蜡藤烯(8.7%),芦丁烯醇(7.7%)和肉豆蔻醇(6.4%); 山茱。(S. officinalis):樟脑(40.2,47.8,45.9%),c-thujone。(19.2,22.2,13.7%),桉木酚(5.4,2.6,6.0%),樟脑(5.8,6.1,3.9,%),冰片(分别来自Tepelena,地拉那和Vlora的样品分别为2.1、2.9、5.7%)和乙酸冰片(3.3、1.4、5.6%)。还使用以下体外试验测试了香精油的自由基清除活性:i)与DPPH(1,1-二苯基-2-picylhydrazyl)的自由基稳定基相互作用,以及ii)抑制亚油酸-过氧化用2,2'-偶氮二-2-甲基丙酰胺酰胺,二盐酸盐(AAPH)。最后,评估了它们对大豆脂氧合酶的抑制活性,以亚油酸为底物。0。vulgare(OV-VL)的香精油与稳定的自由基DPPH(76.5%)的相互作用最高,其次是苦艾草(Absinthium)的(54.7%)。普通农杆菌(O-vulgare,OV-TP)和苦艾酒(A. absinthium)显示出较高的抗脂质过氧化活性,分别比参考化合物trolox(73.0%)高97.5%和96.5%。只有被测试的普通小麦样品(OV-VL)显着抑制了大豆脂氧合酶(54.2%)。
