Green synthesis of metal and metal-oxide nanoparticles pertinent to Catharanthus roseus and Moringa oleifera-A Review

Biological synthesis via greener route attained eclectic interest for research investigators due to their reliable, sustainable, ecofriendly, and non-toxic nature since numerous efforts are made laterally with reflective applications by synthesizing diverse nanomaterials embraces, metals/metal oxide, hybrid, and bioinspired materials during past era. The present review reports and aimed to update and uncover all the minutiae regarding two medicinal plants sources allied with diversified metal and non-metal nanoparticle synthesis thru greener approach. The ornamental, medicinal plants such as Catharanthus roseus and Moringa oleifera have been broadly sightseen for the synthesis of varied nanoparticles due to existence of their innumerable phytochemical configuration which may act as bio-reducing and stabilizing agent by metallic/metal oxides, and non-metallic precursors such as silver, gold, sulphur, copper oxide, iron oxide, ruthenium oxide nanoparticles using either leaves infusions or part/whole plant. This report highlights with a phenomenon of using different parts of these two plants and their applications in varied scientific domains which may act as a promising drug candidates for drug delivery mechanism by means of nano approach.
