采用ABTS法和DPPH法对突尼斯不同产地的玫瑰叶提取物的抗氧化活性进行了评价，而精油和类胡萝卜素提取物的抗氧化活性仅采用ABTS法测定。用福林法测定的总酚含量表明，在Aindraham，与Feija的样品相比，样品显示出很大的酚含量变化。经气相色谱（GC）和气相色谱-质谱联用（GC- ms）分析，飞花精油的主要成分为棕榈酸、维螺烷、亚油酸、月桂酸、肉豆蔻酸和乙酸叶绿醇，而艾因拉罕精油的主要成分为维螺烷、棕榈酸、亚油酸和乙酸叶绿醇。采用高效液相色谱（HPLC）法测定，发现黄芪中含有较高的b-胡萝卜素和番茄红素。所有样品都具有抗氧化活性，但酚提取物比类胡萝卜素提取物更显著，类胡萝卜素提取物具有最低的活性。
The antioxidant activity of leaf extracts of Rosa canina from diverse localities of Tunisia were evaluated by ABTS and DPPH methods, whereas in those of essential oils and carotenoids extracts such activity was determined only by the ABTS method. Total phenols determined by the Folin method revealed that at Aindraham, samples showed a great variability of phenol content in contrast to those from Feija. After chemical analysis of the essential oils by gas chromatography (GC) and gas chromatography coupled to mass spectra (GC-MS), revealed that the oils of Feija were predominantly composed of palmitic acid, vitispirane, linoleic acid, lauric acid, myristic acid and phytol acetate, while in those samples from Aindraham predominated vitispirane, palmitic acid, linoleic acid and phytol acetate. Higher concentrations of b-carotene and lycopene were found in the samples from Aindraham after determination by high performance liquid chromatography (HPLC). All samples possess antioxidant activity, nevertheless much more significant in phenol extracts in contrast to the carotenoid extracts, which possess the lowest activity.
