Characterization of Rheum ribes with ZnO nanoparticle and its antidiabetic, antibacterial, DNA damage prevention and lipid peroxidation prevention activity of in vitro

This study aims to investigate the antidiabetic, antimicrobial, DNA damage, and lipid peroxidation prevention activity of ZnO NPs/Rr formed as a result of the interaction of Rheum ribes (R.ribes) plant with ZnO. The ZnO NPs/Rr obtained as a result of the reaction were confirmed using high-reliability characterization methods. According to the data obtained as a result of the study, it is seen that the activity of ZnO NPs/Rr to prevent lipid peroxidation is quite strong. Lipid peroxidation inhibition activity of ZnO NPs/Rr at the highest concentration of 250 μg/ml was calculated as % 89.1028. It was observed that ZnO NPs/Rr prevented DNA damage by % 92.1240 at the highest concentration of 100 μg/ml. It was determined that the antidiabetic effect of ZnO NPs/Rr formed by ZnO of R. ribes plant, which is used as a medicinal plant as an antidiabetic, was significant. It appears to have a strong antidiabetic property compared to the positive control acarbose. In our current study, it was observed that ZnO NPs/Rr formed zones ranging from 8 ± 3.0 to 21 ± 4.5 against Gram-positive and Gram-negative microorganisms. It has been determined that ZnO nanoparticles have an antibacterial effect.
