AI Summary & Key Takeaways
AI InsightAccording to the data obtained, especially the below-ground hexane (MIC value:375μg/mL) extract showed more antimicrobial activity than other plant extracts, and it was found to be more effective Gram negative bacteria.
📌 3 Key Takeaways
Abstract
In this study, the effects of above and below-ground extracts of Centranthus longiflorus subsp. longiflorus plant, commonly found in Turkey, on antioxidant, antimicrobial and DNA damage were evaluated. Plant extracts were prepared by applying three different solvents (hexane, methanol and ethanol). The antimicrobial activity tests of the extracts were performed using four different standard strains and one yeast. DPPH, total phenolic content calculation and CUPRAC methods were applied for antioxidant activity studies. Additionally, the effects of plant extracts on DNA damage were investigated using pBR322 plasmid DNA. According to the data obtained, especially the below-ground hexane (MIC value:375μg/mL) extract showed more antimicrobial activity than other plant extracts, and it was found to be more effective Gram negative bacteria. The highest antioxidant activity was determined in extracts prepared with above (IC50 value of methanol extract:4.5mg/mL) and below-ground (IC50 value of methanol extract:5.7mg/mL) methanol. The above (93,9 μg GAE/mL) and below-ground (96.9 μg GAE/mL) methanol extracts were seen to have high total phenolic content. It has also been observed that above-ground hexane and methanol extracts have no effect on pBR322 plasmid DNA, but other extracts affect pBR322 plasmid DNA in the direction of degradation or deformation. Especially, the extracts of the above and below-ground ethanol had the effect of completely eliminating the open ring form. Therefore, it was concluded that this taxon could be widely used in the treatment and prevention of oxidative stress-related diseases in the future.
