Antimicrobial Activities of Natural Bioactive Polyphenols

Abstract

Secondary metabolites, polyphenols, are widespread in the entire kingdom of plants. They contain one or more hydroxyl groups that have a variety of biological functions in the natural environment. These uses include polyphenols in food, beauty products, dietary supplements, and medicinal products and have grown rapidly during the past 20 years. Antimicrobial polyphenols are described together with their sources, classes, and subclasses. Polyphenols are found in different sources, such as dark chocolate, olive oil, red wine, almonds, cashews, walnuts, berries, green tea, apples, artichokes, mushrooms, etc. Examples of benefits are antiallergic, antioxidant, anticancer agents, anti-inflammatory, antihypertensive, and antimicrobe properties. From these sources, different classes of polyphenols are helpful for the growth of internal functional systems of the human body, providing healthy fats, vitamins, and minerals, lowering the risk of cardiovascular diseases, improving brain health, and rebooting our cellular microbiome health by mitochondrial uncoupling. Among the various health benefits of polyphenols (curcumin, naringenin, quercetin, catechin, etc.) primarily different antimicrobial activities are discussed along with possible future applications. For polyphenols and antimicrobial agents to be proven safe, adverse health impacts must be substantiated by reliable scientific research as well as in vitro and in vivo clinical data. Future research may be influenced by this evaluation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Phenolics can inactivate vital microbial enzymes by binding to their active sites or altering enzyme conformation, thereby inhibiting metabolic pathways essential for microbial growth and survival.

    “Additionally, phenolics can inactivate vital microbial enzymes by binding to their active sites or altering enzyme conformation, thereby inhibiting metabolic pathways essential for microbial growth and survival (Mandal & Domb, 2024).”

    From Influence of Extraction Parameters on Bioactive Compounds and Antimicrobial Activity of Banana Peel Using Ethanol-Water Solvent (2026) · cites this paper as Mandal & Domb, 2024

    Section 5, “Possible Antimicrobial Mechanisms” (page not provided), says polyphenols inhibit enzymes and that enzyme inhibition can disrupt metabolic pathways, contributing to microbial killing. It does not specify binding to enzyme active sites or altering enzyme conformation as the means of inhibition. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Phenolic compounds exert antimicrobial effects through a diverse array of mechanisms that target key structural and functional components of microbial cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
