The objectives were to study the potential of Althaea officinalis radix in production of silver NPs, and the effect of the extract ethanol concentration on the produced NPs. Seventy and ninety-six percent hydroalcoholic extracts were prepared by percolation of the plant powder. The extract was concentrated by rotary evaporator and then freeze-dried. Silver ions were determined using atomic absorption analysis. The NPs were characterized by Nano-Zeta Sizer and TEM. Both of 70% and 96% of hydroalcoholic extracts of A. officinalis radix successfully synthesized spherical and poly-dispersed silver NPs. The conversion was fast and almost completed in 5 h.
