Special Issue Information

Dear Colleagues,

Plants are an integral part of traditional medicine in the treatment of various diseases. Their numerous compounds and natural products continue to inspire the design, discovery, and development of drugs and nutraceuticals.

Understanding the complex chemical composition and biological activities of plant-based natural products is fundamental in fully utilizing their potential benefits for human health.

Furthermore, the current concept of the ‘one-disease-one-target drug’ is increasingly giving way to a new paradigm in which drugs targeting multiple human physiological pathways are preferable—a concept known as polypharmacology. In this context, the potential of plant-derived products, which comprise complex mixtures of numerous bioactive compounds, is further emphasized.

Developing efficient and safe plant-derived products is a challenging task that demands a multidisciplinary approach. This approach integrates knowledge from various fields such as botany, phytotherapy, phytochemistry, pharmacology, toxicology, biotechnology, legislation, and industrial pharmacy. Therefore, this Special Issue aims to provide an overview of the latest progress in these topics, supporting future discoveries and the development and the utilization of drugs and nutraceuticals that are derived from plant sources. Original research and review articles within this scope are welcome.

This study aimed to evaluate the spasmolytic activity of an underground parts extract of Gentiana asclepiadea L. (Gentianaceae), assess its antioxidant and antimicrobial activities, and explore the impact of extract encapsulation on the aforementioned bioactivities. An extract encapsulated by spray drying with whey protein, pure extract, and pure whey protein were comparatively tested. The main compounds identified via HPLC-DAD analysis underwent in silico ADME assessment. The spasmolytic effect was tested on a model of spontaneous rat ileum contractions, and the mechanism of action was further evaluated on acetylcholine-, KCl-, CaCl2-, BaCl2-, histamine-, N(ω)-nitro-L-arginine methyl ester-, and glibenclamide-modified contractions. The most abundant compounds were secoiridoids (dominantly gentiopicroside), followed by C-glycosylated flavonoids and xanthones. Both pure and encapsulated extracts achieved significant spasmolytic effects, despite the spasmogenic activity of pure whey protein. The extract may exert its spasmolytic effect through multiple pathways, predominantly by antagonizing the Ca2+ channel and opening the K+ channel, while the nitric oxide pathway appears not to be involved. The antimicrobial and antioxidant activities of the pure extract were moderate. The extract stabilized by encapsulation retained all of the tested bioactivities of the unencapsulated extract. The obtained results suggest that G. asclepiadea has potential for use in the treatment of some gastrointestinal complaints and that the encapsulated extract could be a valuable functional ingredient in pharmaceutical and food products.
