The Argentinean Northwestern (NWA) region is renowned for its rich biodiversity, with a wide variety of wild plant species traditionally used for medicinal, culinary, and aromatic purposes. Plant species from the Asteraceae family are known for their bioactive compounds with antioxidant properties, making them both suitable as functional ingredients for novel food formulations. This study aimed to evaluate four native Asteraceae species from Northwestern Argentina as potential ingredients for developing functional foods: Tagetes minuta, Tagetes terniflora, Chromolaena hookeriana and Tessaria dodoneifolia. The experimental design included drying, maceration, filtration, and extraction by conventional and supercritical fluid methodology. The antioxidant capacity, antimicrobial activities, phenolic content, toxicity, and identification of bioactive compounds were analyzed by high-performance liquid chromatography with diode array detection. Results showed that species C. hookeriana and T. dodoneifolia displayed outstanding antioxidant properties, with over 90% radical-scavenging activity, and high phenolic compounds content, exceeding 220 mg GAE/100 g in conventional extraction and 160 mg GAE/100 g in supercritical extraction, along with antimicrobial activity in supercritical extracts. In the species C. hookeriana, phenolic compounds were found: rutin, p-coumaric acid, ferulic acid, quercetin, and nordihydroguaiaretic acid. In the species T. dodoneifolia, in addition to these, naringenin was found, a compound with antioxidant activity of nutritional interest for food design. None of the tested plant species showed toxicity, according to the Artemia salina L. bioassay. This research advances the field of functional foods and opens new perspectives for developing innovative health-promoting products.
阿根廷西北部地区以其丰富的生物多样性而闻名，有各种各样的野生植物物种，传统上用于药用、烹饪和芳香用途。菊科植物因其具有抗氧化特性的生物活性化合物而闻名，这使其既适合作为新型食品配方的功能性成分。本研究旨在评估来自阿根廷西北部的四种菊科本土物种作为开发功能性食品的潜在成分：细叶万寿菊、三叶万寿菊、胡氏假泽兰和多氏斑鸠菊。实验设计包括干燥、浸渍、过滤以及通过常规和超临界流体方法进行提取。通过二极管阵列检测的高效液相色谱法分析了抗氧化能力、抗菌活性、酚类含量、毒性以及生物活性化合物的鉴定。结果表明，胡氏假泽兰和多氏斑鸠菊表现出出色的抗氧化特性，自由基清除活性超过90%，酚类化合物含量高，常规提取中超过220毫克没食子酸当量/100克，超临界提取中超过160毫克没食子酸当量/100克，超临界提取物还具有抗菌活性。在胡氏假泽兰中发现了酚类化合物：芦丁、对香豆酸、阿魏酸、槲皮素和去甲二氢愈创木酸。在多氏斑鸠菊中，除了这些之外，还发现了柚皮素，一种对食品设计具有营养意义的具有抗氧化活性的化合物。根据卤虫生物测定，所测试的植物物种均未显示出毒性。这项研究推动了功能性食品领域的发展，并为开发创新的健康促进产品开辟了新的前景。
