Pectin is one of the finest natural polymer which has drawn great attention because of its applications in different fields. Due to the quintessential structure of pectin, it can be transformed into variety of useful products. It can be utilized as a blend in many polymers to make a mixture or a composite material. Owing to considerable collection in chemical conformation and crosslinking mechanism, different pectin based hydrogels have been prepared for different characteristics in pharmaceutical and bio-medical sites. Inventive properties of hydrogels like volubility, swellability, solvability and hydrophilicity make them better alternative for wastewater treatment. Recently, pectin based hydrogels have demonstrated excellent performance to eliminate various metal ions and dyes from the polluted water. The adsorption

Fruit extracts have natural bioactive molecules that are known to possess significant therapeutic potential. Traditionally, metallic nanoparticles were synthesized via chemical methods, in which the chemical act as the reducing agent. Later, these traditional metallic nanoparticles emerged as the biological risk, which prompted researchers to explore an eco-friendly approach. There are different eco-friendly methods employed for synthesizing these metallic nanoparticles via the usage of microbes and plants, primarily via fruit extract. These explorations have paved the way for using fruit extracts for developing nanoparticles, as they eliminate the usage of reducing and stabilizing agents. Metallic nanoparticles have gained significant attention, and are used for diverse biological applications. The present review discusses the potential activities of phytochemicals, and it intends to summarize the different metallic nanoparticles synthesized using fruit extracts and their associated pharmacological activities like anti-cancerous, antimicrobial, antioxidant and catalytic efficiency.

CuO-MgO nanocomposites were prepared by a solvothermal procedure. Analysis of the X-ray diffraction patterns of the nanoparticle samples showed the formation of minor second phase CuO in addition to the MgO as major phase. On the other hand, TEM images showed CuO minor phase nanoparticles embedded in the MgO matrix. Catalytic properties of these nanomaterials were then investigated with respect to increase in CuO component in the nanocomposite. Three different catalytic reactions for treatment of model pollutants were selected for this purpose. These were the catalytic reduction of p-nitrophenol, catalytic degradation of methyl orange and methylene blue. In all cases the catalytic activity was found to increase with amount of CuO in the nanocomposite. The catalytic efficiencies of all three reactions were high and followed zero-order kinetics. 17induction time increased in a systematic manner with CuO content (Fig. 10b). Possibly, dissolved Fig. 9 UV-vis spectra for degradation of MO by NaBH 4 in presence of CMS-0 (a) and CMS-1 catalyst (b).
