The antioxidant and antibacterial activities, and total phenolic contents of Rosa damascena Mill. flower extracts (absolute, essential oil and hydrosol) were investigated. The chemical compositions of these extracts were analysed by GC-MS. Phenylethyl alcohol (78.38%) was found to be the main constituent of rose absolute, while citrenellol and geraniol were the major compounds (>55%) of rose essential oil and hydrosol. Tocopherol and carotene levels were determined by high performance liquid chromatography (HPLC) analysis. The levels of beta carotene (422.3+/-35.6 ppm), alpha tocopherol (2397.1+/-72.5 ppm) and gamma tocopherol (343.1+/-28.4 ppm) of rose absolute were found to be higher than that of essential oil and hydrosol. Their total phenolic contents were also evaluated. The total phenolic content of the tested extracts varied from 5.2 to 2134.3 GAE/mg L(-1). Rose absolute and essential oil contained high levels of phenolics and demonstrated strong antibacterial activity against Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), Bacillus subtilis (ATCC 6633), Staphylococcus aureus (ATCC 6538), Chromobacterium violaceum (ATCC 12472) and Erwinia carotovora (ATCC 39048) strains.
对大马士革蔷薇花提取物（净油、精油和纯露）的抗氧化和抗菌活性以及总酚含量进行了研究。通过气相色谱 - 质谱联用仪（GC - MS）分析了这些提取物的化学成分。发现苯乙醇（78.38%）是玫瑰净油的主要成分，而香茅醇和香叶醇是玫瑰精油和纯露的主要化合物（>55%）。通过高效液相色谱（HPLC）分析测定了生育酚和胡萝卜素的含量。发现玫瑰净油中β - 胡萝卜素（422.3±35.6 ppm）、α - 生育酚（2397.1±72.5 ppm）和γ - 生育酚（343.1±28.4 ppm）的含量高于精油和纯露。还评估了它们的总酚含量。测试提取物的总酚含量在5.2至2134.3 GAE/mg L(-1)之间变化。玫瑰净油和精油含有高水平的酚类物质，并对大肠杆菌（ATCC 25922）、铜绿假单胞菌（ATCC 27853）、枯草芽孢杆菌（ATCC 6633）、金黄色葡萄球菌（ATCC 6538）、紫色色杆菌（ATCC 12472）和胡萝卜软腐欧文氏菌（ATCC 39048）菌株表现出较强的抗菌活性。
