• Extracts of plant Hibiscus sabdariffa was used for synthesis of gold nanoparticles.
• Stability of the gold nanoparticles was studied in presence of glucose.
• Cytotoxicity of nanoparticles was studied against U87 Glioblastoma multiforme.
• Nanoparticles were investigated for cyctotoxicity under hyperglycemic condition.
In the present paper, a facile synthesis of gold nanoparticles is reported with leaf and stem extract of Hibiscus sabdariffa. Structural features of as synthesized nanoparticles are characterized by UV–vis spectroscopy, XRD, FTIR, and XPS. Morphology of the above synthesized gold nanoparticles is investigated by electron microscopy. The stability of the nanoparticles is studied in different concentrations of glucose which suggested their possible application under hyperglycemic condition. As synthesized nanoparticles has shown selective toxicity towards U87 glioblastoma multiforme cell line under normal and hyperglycemic condition, indicating their potential to be used in the development of value-added products in the biochemical industries. The possible mode of activity of the above nanoparticles has been studied by in vitro molecular techniques.
