L., or European goldenrod, has a long tradition in folk medicine due to the wide range of its biological activity. This paper aimed to investigate the antimicrobial and antioxidative potential of essential oil and hydrolates obtained by traditional and novel extraction techniques. For that purpose, hydrodistillation, microwave-assisted hydrodistillation and solvent-free extraction were performed. Analysis of the composition of essential oils indicated the presence of 59 different compounds with cyclocolorenone, germacrene D and spathulenol being the dominant in all essential oil samples. Antimicrobial activity was detected in all the analyzed samples, with higher effect on Gram-positive microorganisms compared to Gram-negative. Regarding the type of performed extraction process, the introduction of microwaves induced higher antimicrobial and antioxidative potential in both essential oils and hydrolates. Hydrolates obtained in microwave-assisted processes had pronounced antioxidative activity, which creates a good basis for further investigation of this side product's potential use in the food, cosmetic and pharmaceutical industries.
欧洲一枝黄花（Solidago virgaurea L.）因其广泛的生物活性，在民间医学中有着悠久的传统。本文旨在研究通过传统和新型提取技术获得的精油和纯露的抗菌和抗氧化潜力。为此，进行了水蒸馏、微波辅助水蒸馏和无溶剂提取。精油成分分析表明存在59种不同的化合物，环色烯酮、杜松烯D和匙叶桉油烯醇在所有精油样品中占主导地位。在所有分析样品中均检测到抗菌活性，对革兰氏阳性微生物的作用比对革兰氏阴性微生物的作用更强。关于所进行的提取工艺类型，微波的引入使精油和纯露都具有更高的抗菌和抗氧化潜力。微波辅助工艺获得的纯露具有显著的抗氧化活性，这为进一步研究该副产品在食品、化妆品和制药行业的潜在用途奠定了良好基础。
