چکیده
Abstract Biosynthesis of nanoparticles is the preferred route for fabrication biocompatible and cheaper drugs. In this study, extract major secondary metabolite from Helichrysum aureonitens , 3,5-dihydroxy-6,7,8-trimethoxyflavone, were used to synthesize silver zinc oxide nanoparticles. Spectroscopic microscopic techniques confirmed formation The flavone alone showed higher DPPH radical scavenging ability (IC 50 = 487.1 μg mL −1 ) relative control, butylated hydroxytoluene. addition, synthesized using had ferric reducing potential (Fe 3+ Fe 2+ compared other test samples. cytotoxic activity plant extract, flavone, their biosynthesized was also investigated MTT assay against cancerous MCF-7 (breast adenocarcinoma) A549 (human lung adenocarcinoma)), non-cancerous HEK293 embryonic kidney) cell lines. decreased viability 68.6 without being HEK293, even at high concentrations. Silver significantly moderately but induced death low This study provides a green synthesis confirms therapeutic effectiveness H. thereby validating its use in ethnomedicine.

Mushrooms (Agaricus bisporus) mediated biosynthesis of sliver nanoparticles, characterization and their antimicrobial activity
In this paper we report an eco-friendly route for the synthesis of sliver nanoparticles using Agaricus bisporus (white button mushroom) extract. The synthesized silver nanoparticles were confirmed and characterized by UV-Visible spectrum of the aqueous solution containing silver ions showed a peak at 420 nm corresponding to the surface plasmon absorbance of silver nanoparticles. Transm...
