The fruits of eight myrtles, Myrtus communis L. accessions from the Mediterranean region of Turkey were evaluated for their antioxidant activities and fatty acid contents. The antioxidant activities of the fruit extracts were determined by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and beta-carotene-linoleic acid assays. The fatty acid contents of fruits were determined by using gas chromatography. The methanol extracts of fruits exhibited a high level of free radical scavenging activity. There was a wide range (74.51-91.65%) of antioxidant activity among the accessions in the beta-carotene-linoleic acid assay. The amount of total phenolics (TP) was determined to be between 44.41-74.44 mug Gallic acid equivalent (GAE)/mg, on a dry weight basis. Oleic acid was the dominant fatty acid (67.07%), followed by palmitic (10.24%), and stearic acid (8.19%), respectively. These results suggest the future utilization of myrtle fruit extracts as food additives or in chemoprevention studies.
对来自土耳其地中海地区的8个香桃木(Myrtus communis L.)品种的果实进行了抗氧化活性和脂肪酸含量评估。通过2,2-二苯基-1-苦基肼(DPPH)和β-胡萝卜素-亚油酸测定法测定果实提取物的抗氧化活性。采用气相色谱法测定果实的脂肪酸含量。果实的甲醇提取物表现出较高的自由基清除活性。在β-胡萝卜素-亚油酸测定中,各品种间的抗氧化活性范围很广(74.51-91.65%)。以干重计,总酚(TP)含量在44.41-74.44μg没食子酸当量(GAE)/mg之间。油酸是主要脂肪酸(67.07%),其次是棕榈酸(10.24%)和硬脂酸(8.19%)。这些结果表明香桃木果实提取物未来可作为食品添加剂或用于化学预防研究。
