Journal ArticleDOI
Malva parviflora extract assisted green synthesis of silver nanoparticles.
TL;DR: The present process is an excellent candidate for the synthesis of silver nanoparticles that is simple, easy to perform, pollutant free and inexpensive.
Journal ArticleDOI
Phoenix dactylifera L. leaf extract phytosynthesized gold nanoparticles; controlled synthesis and catalytic activity.
Mervat F. Zayed,Wael H. Eisa +1 more
TL;DR: F Fourier transform infrared (FTIR) analysis suggests that the synthesized gold nanoparticles might be stabilized through the interactions of hydroxyl and carbonyl groups in the carbohydrates, flavonoids, tannins and phenolic acids present in P. dactylifera.
Journal ArticleDOI
Clean production of powdery silver nanoparticles using Zingiber officinale: The structural and catalytic properties
TL;DR: In this article, a clean, eco-friendly, inexpensive, and easy-to-operate solid state synthetic route is developed to prepare silver nanoparticles using Zingiber officinale (Ginger) powder.
Journal ArticleDOI
Naturally Occurring Xanthones; Latest Investigations: Isolation, Structure Elucidation and Chemosystematic Significance
Hesham R. El-Seedi,Dina M.H. El-Ghorab,Mai A. El-Barbary,Mervat F. Zayed,Ulf Göransson,Sonny Larsson,Robert Verpoorte +6 more
TL;DR: An updated literature survey covering the reports of naturally occurring xanthones in the period of 2005-2008 is presented and plant origin, the way of separation, and spectral analysis done for structure elucidation are discussed.
Journal ArticleDOI
In-vitro antioxidant and antimicrobial activities of metal nanoparticles biosynthesized using optimized Pimpinella anisum extract
TL;DR: In this article, Pimpinella anisum seeds were extracted under various conditions (solvent type, temperature, solvent/plant ratio and contact time). The potency of the resulted extracts towards biosynthesis of silver and gold nanoparticles was assessed.
