The field of plant polyphenols has garnered significant attention due to their potential therapeutic benefits and diverse chemical structures. These secondary metabolites, which include phenolic acids, flavonoids, anthocyanins, tannins, lignans, and stilbenes, are known for their role in combating free radical-linked diseases. Despite their promising biological potential, polyphenols often present challenges in research, particularly due to their propensity to yield false positive results in in vitro studies, leading to debates about their pharmacological relevance. Recent advancements in analytical methodologies have enabled the isolation of high-purity polyphenolic compounds, facilitating more accurate pharmacological investigations. However, there remains a need for comprehensive studies to better understand the pharmacokinetics and therapeutic applications of these compounds, as well as to address the issue of pan-assay interference.

This research topic aims to gather scientific evidence that identifies novel pharmacological properties of known and new polyphenolic substances in plants. It seeks to explore methods for their recovery from plant material on both analytical and industrial scales. By employing suitable methodologies and control experiments, the research will address the challenges associated with pan-assay interference, ultimately enhancing the understanding of polyphenols' impact on human health.

To gather further insights into the identification and application of bioactive polyphenols, we welcome articles addressing, but not limited to, the following themes:

- Optimization studies on plant material
- Fingerprinting of plant extracts for pharmacological potential
- Isolation protocols for recovering pharmacologically potent molecules
- Application of green chemistry principles in plant drug preparation
- Impact of polyphenols on biological functions
- Investigation of molecular mechanisms of polyphenols’ activity
