Green formulation of Ag nanoparticles by Hibiscus rosa-sinensis: Introducing a navel chemotherapeutic drug for the treatment of liver cancer

An eco-friendly biosynthesized Ag NPs immobilized Hibiscus rosa-sinensis extract has been introduced. The as-prepared nanoparticles were characterized using UV-Vis, SEM, and FT-IR analysis. In the FT-IR test, the presence of many antioxidant compounds with related bonds caused the excellent condition for reducing of silver in the silver nanoparticles. In UV-Vis, the clear peak in the wavelength of 428 nm indicated the formation of silver nanoparticles. The synthesized nanoparticles had very low cell viability and high anti-liver cancer activities dose-dependently against pleomorphic hepatocellular carcinoma (SNU-387), hepatic ductal carcinoma (LMH/2A), morris hepatoma (McA-RH7777), and novikoff hepatoma (N1-S1 Fudr) cell lines without any cytotoxicity on the normal cell line (HUVEC). The synthesized nanoparticles inhibited half of the DPPH molecules in the concentration of 78 mg/mL. Perhaps notable anti-liver cancer activities of the synthesized nanoparticles against common liver cancer cell lines are linked to their antioxidant activities.
