Biological Properties of Hydrastis Canadensis Using Copper Nanoparticles

Abstract: The perennial plant Hydrastis canadensis, more often known as goldenseal, has a long history of usage in herbal medicine due to its many beneficial characteristics, such as its ability to enhance the immune system, reduce inflammation, and fight against microbes. Berberine, hydrastine, and canadine are three of the bioactive components of Hydrastis canadensis that have shown promising results in treating a range of medical issues, including inflammation, bacterial infections, and gastrointestinal problems. Natural plant extracts have the potential to be medicinal, but they often encounter obstacles in terms of bioavailability, stability, and site delivery. Despite these obstacles, a new strategy for improving medicinal plants' biological activity—the use of nanotechnology, and more especially nanoparticles derived from metals—has arisen. Copper nanoparticles mediated by Hydrastis canadensis were extensively studied for their biological characteristics. Use of disc diffusion and minimum inhibitory concentration (MIC) tests allowed for the evaluation of antimicrobial efficacy against a wide range of bacterial and fungal pathogens, including Gram-positive and Gram-negative strains. The DPPH (2,2-diphenyl-1- picrylhydrazyl) radical scavenging tests were used to assess the antioxidant potential of the produced nanoparticles. The results showed that the nanoparticles had better free radical scavenging activity than either the plant extract or the copper nanoparticles alone. Biofunctionalized CuNPs also showed encouraging anticancer activity by inhibiting cancer cell growth and inducing apoptosis when evaluated on different cancer cell lines using MTT tests. This research found that adding copper nanoparticles to Hydrastis canadensis significantly increased its biological activity. The enhanced bioavailability, surface reactivity, and stability of the nanoparticles are responsible for the observed synergistic impact. This unique nanocomposite shows promise as a therapeutic agent candidate due to its enhanced antibacterial, antioxidant, and cytotoxic capabilities relative to its constituent parts, according to the results. Finally, this study lays the groundwork for a unique strategy in nanomedicine and pharmaceutical sciences: the investigation of copper nanoparticles mediated by Hydrastis canadensis. The green synthesis process improves medicinal plants' pharmacological potential while also providing an economical and environmentally friendly alternative to nanoparticle manufacturing. For a complete understanding of how these biofunctionalized nanoparticles work and to confirm their therapeutic potential in treating cancer, oxidative stress diseases, and drug-resistant infections, more in vivo investigations and clinical trials are needed.
