Caffeic acid (CA) is found abundantly in fruits, vegetables, tea, coffee, oils, and more. CA and its derivatives have been used for many centuries due to their natural healing and medicinal properties. CA possesses various biological and pharmacological activities, including antioxidant, anti-inflammatory, anticancer, and neuroprotective effects. The potential therapeutic effects of CA are mediated via repression and inhibition of transcription and growth factors. CA possesses potential anticancer and neuroprotective effects in human cell cultures and animal models. However, the biomolecular interactions and pathways of CA have been described highlighting the target binding proteins and signaling molecules. The current review focuses on CA’s chemical, physical, and pharmacological properties, including antioxidant, anti-inflammatory, anticancer, and neuroprotective effects. We further described CA’s characteristics and therapeutic potential and its future directions.

“…According to previous experimental exploration and literature reports, an alkaline environment is more conducive to the preparation of stable and uniform PtNPs solution [ 22 , 23 ]. The CE was adjusted from the original pH 6.0 to the pH 10.0, and then 50 mL CE was added to 50 mL H 2 PtCl 6 (1 mmol/L) aqueous solution.…”

The aim of this work is to develop a green route for platinum nanoparticles (PtNPs) biosynthesized using Cordyceps flower extract and to evaluate their antioxidant activity and antibacterial activity. Different characterization techniques were utilized to characterize the biosynthetic PtNPs. The results showed that PtNPs were spherical particles covered with Cordyceps flower extract. The average particle size of PtNPs in Dynamic Light Scattering was 84.67 ± 5.28 nm, while that of PtNPs in Transmission Electron Microscope was 13.34 ± 4.06 nm. Antioxidant activity of PtNPs was evaluated by DPPH free radical scavenging ability test. The results showed that the antioxidant activity was positively correlated with the concentration of PtNPs, the DPPH scavenging efficiency of PtNPs (0.50–125.00 μg/mL) was 27.77–44.00%. In addition, the morphological changes of four kinds of bacteria (Escherichia coli, Salmonella typhimurium, Bacillus subtilis, Staphylococcus aureus) exposed to PtNPs were observed by scanning electron microscope. The results showed that the antibacterial activity of PtNPs against Gram-negative bacteria was stronger than that of Gram-positive bacteria.

“…In addition to being crucial for the production and application of PtNPs, the development of simple and environmentally friendly synthesis techniques also support the growing eld of green chemistry [21]. According to previous literature platinum nanoparticles were synthesized by using plant extracts Atriplex halimus [12], green tea powder [22], Saudi dates extract [23], Xanthium strumarium [24] Punica granatum [25], Nigella sativa L.[26], Antigonon leptopus [27], Garcinia mangostana L. [28], orange peel [29] etc. These plant extracts are made up of several distinct ingredients.…”

The clinical medicine, also referred to as biomedicine, is being revolutionised by the growing usage of nanotechnology. Platinum nanoparticles (PtNPs), due to its stability and other properties, are found to be particularly more effective in biomedicine. However, the traditional chemical and physical methods of production of PtNPs have brought about some severe concerns to environmental and human health directly, or indirectly that mainly includes land and water pollution. There is need to overcome such concerns raised by replacing traditional methods by environment friendly ones. For this purpose, Cichorium intybus (C. Intybus) is a significant member of the Asteraceae family of medicinal plants, and has been used in traditional medicine for almost a century. In this research, for synthesis of nanoparticles via sustainable, green and environment friendly approach, C. Intybus leaves extract is used as a precursor. For this, leaves were extracted under five different solvent systems such as 80% methanol, 80% ethanol, methanol (absolute), ethanol (absolute), and de-ionized water. The phytochemical analysis reflected that the greatest extract yield (12.79 g/100 g DW) was obtained from leaves in an 80% methanolic solvent solution. The results indicated that the 80% methanolic leaf extract had the highest total phenolic content (93.24 mg GAE/g DW) and the maximum total flavonoid content (8.92 mg CE/g DW) of methanolic leaf extract. 2, 2-diphenyl-1-picrylhydrazyl (DDPH) radical scavenging activity and reducing power were used to determine antioxidant activity. The results revealed that 80% methanolic leaf extract showed the highest level of radical scavenging activity and reducing potential. In UV-visible spectroscopy, a colour change and a surface resonance plasmon band at 295 nm confirmed the production of PtNPs in the reaction mixture. The green methods of nanoparticles like the one presented in this study, have a promising potential to minimize negative impacts on the environmental health. This study paves a path for further research and development in this regard.
