Numerous attempts have been made for green synthesis of metal oxide nanoparticles; revealing the significance of plant extracts in reducing metal sources to nanoparticles and applications in various scientific domains. Catharanthus roseus is an evergreen herbaceous plant, belonging to the family Apocynaceae. Its leaves are reported to contain several phytochemicals like indole alkaloids like vinblastine, vincristine, vindesine. This article focuses on applications of Catharanthus roseus leaves extract in the fabrication of nanoparticles of various metal oxides like copper oxide, zinc oxide, titanium dioxide, and nickel oxide. These metal oxide nanoparticles were evaluated in many research studies for a variety of uses, including antibacterial, and photocatalytic properties. The utilization of Catharanthus roseus leaf aqueous extract revealed that its phytocompounds were involved in lowering the metal oxides and stabilizing their nanoparticles. In conclusion, it could be noted that metal oxide nanoparticles have antimicrobial activity and photocatalytic potential.
Keywords: Catharanthus roseus; metal oxide nanoparticles; Green synthesis; applications.
