摘要

本研究在Fenton试剂环境下，研究了金针桃和伊塔布兰提取物对脂质过氧化(LPO)形成和不饱和脂肪酸的预防作用。体外实验分为四组，第一组为对照组，第二组为Fenton试剂(FeCl2+H2O2, Fenton R)，第三组为Fenton试剂加棘球茅提取物，第四组为Fenton试剂加棘球茅提取物。实验结果显示，与对照组相比，棘毛鼠组LPO水平有部分下降(p<0.05)，而棘毛鼠组LPO水平明显升高(p<0.001)。与spicata组相比，Fenton R组的LPO水平增加了10倍(p <0.0001)，其中Q. ithaburensis组降低了50% (p <0.001)。体外环境下的脂肪酸水平分析表明，钉子户和山楂提取物对DPPH自由基的清除能力与槲皮素相当(p<0.05)。体外环境下，钉子户和山楂提取物的脂肪酸含量均高于Fenton R组(p<0.001)。我们的实验结果证实，在Fenton试剂环境中，spicata和ithaburenis提取物降低了LPO水平，并显著保护环境中的不饱和脂肪酸免受自由基来源的氧化。

Radical Scavenging Activity of Thymbra spicata and Quercus ithaburensis in a Fenton Reagent Environment and Their Protective Effects on Unsaturated Fatty Acids

In this study, the aim is to investigate the preventive effects of T. spicata and Q. ithaburensis extracts on lipid peroxidation (LPO) formation and unsaturated fatty acids in a Fenton reagent environment. The in vitro experiments were divided into four groups, the first group being the control, the second group Fenton’s reagent (FeCl2+H2O2, Fenton R), the third group Fenton’s reagent plus T. spicata extracts, and the fourth group Fenton’s reagent plus Q. ithaburensis extracts. According to the experimental results, while the LPO level in the T. spicata group partially decreased (p<0.05), the LPO level in the Q. ithaburensis group was distinctly high (p<0.001) compared to the control group. The LPO level in the Fenton R group when compared to the T. spicata group, increased ten-fold (p <0.0001), where the Q. ithaburensis group decreased by 50% (p <0.001). When the DPPH radical scavenging activity of the extracts of T. spicata and Q. ithaburensis were examined, they were found to be as effective as quercetin (p<0.05) The fatty acid levels were analyzed for the in vitro environment, the amount of fatty acids in the T. spicata and Q. ithaburensis groups were higher than that of the Fenton R group (p<0.001). Our test results confirm that T. spicata and Q. ithaburensis extracts decreased the LPO level in the Fenton reagent containing environment and they noticeably protect the unsaturated fatty acids in the environment from radical sourced oxidations.

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
