高级氧化体系中自由基模拟的研究进展

Gongye shui chuli, 2022
自由基模拟因可以深入了解高级氧化技术（AOPs）的内部机制及动力学规律而受到广泛关注。利用准稳态模型可以较好地模拟体系中的自由基分布，深入了解AOPs体系中的反应机制；基于第一性原理的动力学模型可以有效地模拟体系内不同物质的浓度变化，实现水质变化条件下体系中污染物降解的动态预测。自由基模拟已在基于‧OH、SO4·-及含氯自由基的AOPs体系内广泛应用，最新的研究表明自由基模拟可同样推广至基于有机自由基的AOPs体系。综述了自由基准稳态模型在纯水体系及复杂基质中的应用情况 ...

麻疯树籽仁/壳乙醇提取物的体外抗氧化活性In vitro antioxidant activity of ethanol extracts of Jatropha curcas seed kernel and shell

Zhongguo youzhi, 2022
为了提高麻疯树种子的开发利用价值，采用体外抗氧化实验对麻疯树籽仁/壳乙醇提取物抗氧化活性进行了研究。分别以麻疯树种子中的籽仁和籽壳为原料，经75%乙醇提取，在对提取物主要成分进行分析的基础上，以VE为阳性对照，测定两种提取物对自由基（DPPH自由基、ABTS+自由基、羟自由基和超氧自由基）的清除能力、还原能力以及抑制亚油酸自氧化能力。结果表明：麻疯树籽仁/壳乙醇提取物中多糖类物质总含量分别为47.67%和52.21%，酮类物质总含量分别为0.774%和 4.22%，麻疯树籽壳乙醇提取物中还含有0.30 ...

干燥方式对迷迭香脂溶性抗氧化物质 得率及抗氧化活性的影响 Effects of drying methods on yield and antioxidant activity of fat-soluble antioxidant components from Rosmarinus officinalis

Zhongguo youzhi, 2022
通过研究不同生长期对迷迭香脂溶性抗氧化物质（鼠尾草酸、鼠尾草酚和熊果酸）得率的影响筛选出最佳生长期，在此基础上测定不同干燥方式（阴干、烘干（45 ℃）和晾晒）下迷迭香脂溶性抗氧化物质得率，DPPH自由基、ABTS+自由基、羟自由基清除能力和铁还原力，以考察不同干燥方式对迷迭香脂溶性抗氧化物质抗氧化活性的影响。结果表明：迷迭香抗氧化物质积累的最佳生长期为10个月，3种不同干燥方式中烘干处理的迷迭香所提脂溶性抗氧化物质的得率最大，DPPH自由基、ABTS+自由基、羟自由基清除能力和铁还原力均最强 ...
