Abstract

Food products contaminated with pathogens and spoiled not only lead to a decrease in the quality and quantity of food products but also contribute to the spread of diseases, which are increasingly becoming a public health problem in both developed and developing countries. Due to the multiple resistance of these pathogens to antibiotics, the search for natural products with antimicrobial properties is becoming increasingly important. Inula viscosa has been used as a medicinal plant for a long time in many Mediterranean countries. The aim of this study was to investigate the antimicrobial effects of I. viscosa extracts against foodborne pathogens and their non-enzymatic antioxidant potential. Antimicrobial activity was measured using the disc diffusion method. Additionally, plant extracts were tested against 2,2-Diphenyl-1-picrylhydrazyl and 2,2'-azinobis (3-ethyl-benzothiazoline 6-sulfonate) radicals for antioxidant activity. Inula viscosa showed the highest antibacterial activity against Bacillus subtilis with the methanol extract (19 mm zone diameter), while the lowest activity was observed against Salmonella Typhimurium, with inhibition zone diameters of 7 mm. The highest antioxidant activity was recorded as 77.5% for the DPPH• method and 73.8% for the ABTS• method. In conclusion, this plant can be considered a natural antimicrobial and antioxidant agent against foodborne pathogens, and it is a promising candidate for large-scale experiments.

粘菊(菊科):抗菌和抗氧化活性的色谱指纹图谱研究
被病原体污染和变质的食品不仅导致食品的质量和数量下降,而且还导致疾病的传播,这在发达国家和发展中国家都日益成为一个公共卫生问题。由于这些病原体对抗生素具有多重耐药性,寻找具有抗菌特性的天然产物变得越来越重要。粘胶菊在许多地中海国家被用作药用植物已经很长时间了。本研究的目的是研究粘菌提取物对食源性致病菌的抑菌作用及其非酶抗氧化潜力。采用圆盘扩散法测定其抑菌活性。此外,还测试了植物提取物对2,2-二苯基-1-吡啶肼基和2,2'-氮化喹啉(3-乙基-苯并噻唑啉6-磺酸盐)自由基的抗氧化活性。甲醇提取物对枯草芽孢杆菌的抑菌活性最高(带直径19 mm),对鼠伤寒沙门菌的抑菌活性最低(带直径7 mm)。DPPH•法抗氧化活性最高,为77.5%,ABTS•法抗氧化活性最高,为73.8%。综上所述,该植物可被认为是一种天然的抗食源性病原体的抗菌和抗氧化剂,具有大规模实验的潜力。
