Zn(II) Complex of Plant Phenolic Chlorogenic Acid: Antioxidant, Antimicrobial and Structural Studies

Abstract: The structure of the Zn(II) complex of 5-caffeoylquinic acid (chlorogenic acid, 5-CQA) and the type of interaction between the Zn(II) cation and the ligand were studied by means of various experimental and theoretical methods, i.e., electronic absorption spectroscopy UV/Vis, infrared spectroscopy FT-IR, elemental, thermogravimetric and density functional theory (DFT) calculations at B3LYP/6-31G(d) level. DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), FRAP (f… Show more

“…Phenolic compounds play a significant role in plant tolerance to toxic metals, together with the prevention and reduction of biotic and abiotic oxidative stress [ 4 ]. Chlorogenic acid (5-caffeoylquinic acid, 5-CQA) is a phenolic compound considered to play an essential role in defense against biotic and abiotic stresses and is accumulated in plant tissues exposed to different stress factors that result in increased ROS production [ 4 ]. Zinc (Zn) cations and Zn complexes have anti-/pro-oxidant and antimicrobial activities [ 4 ].…”

Zinc (Zn) cations and Zn complexes have anti-/pro-oxidant and antimicrobial activities [ 4 ]. The antimicrobial activity of the Zn(II) complex of 5-CQA and 5-CQA against Escherichia coli , Pseudomonas aeruginosa , Bacillus subtilis , Staphylococcus aureus , Salmonella enteritidis and Candida albicans was tested by Kalinowska et al [ 4 ].…”
