Abstract

This study delved into the incorporation of wild nettle (Urtica dioica L.) leaves powder with virgin olive oil, exploring its potential to enhance nutritional value and health benefits. The antioxidant, antibacterial, and mineral-enrichment attributes of the resultant nettle-infused olive oil were investigated. Phenolic composition analysis revealed that an optimal maceration time of 30-40 minutes leads to maximal phenolic and flavonoid contents (57.66 mg GAE/100 g and 67.18 mg QE/100 g, respectively). The infused oil demonstrated superior radical scavenging activity (DPPH and ABTS assays) compared to virgin olive oil. Notably, nettle infusion significantly elevates zinc (10.12 mg/kg) and iron (13.85 mg/kg) contents. Antibacterial assays exhibited enhanced inhibition diameters and lower MIC and MBC values for nettle-infused oil against various bacterial strains. The study's findings underscore the potential of nettle infusion to enhance the nutritional and functional attributes of olive oil, holding promise for novel culinary and health applications.

探索野生荨麻和橄榄油的协同潜力:生物活性化合物、抗氧化能力和抗菌特性。

本研究深入研究了野生荨麻(Urtica dioica L.)叶粉与初榨橄榄油的结合，探索其提高营养价值和健康益处的潜力。研究了所得荨麻浸渍橄榄油的抗氧化、抗菌和富含矿物质的特性。酚类成分分析表明，浸渍时间为30 ~ 40 min时，黄酮类和酚类含量最高，分别为57.66 mg GAE/100 g和67.18 mg QE/100 g。与初榨橄榄油相比，注入的橄榄油显示出优越的自由基清除活性(DPPH和ABTS检测)。值得注意的是，荨麻注射液显著提高锌(10.12 mg/kg)和铁(13.85 mg/kg)含量。抑菌试验表明，荨麻浸渍油对多种菌株的抑制直径增大，MIC和MBC值降低。这项研究的发现强调了荨麻注射液在提高橄榄油的营养和功能属性方面的潜力，有望用于新的烹饪和健康应用。

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
