Synthesis of biogenic silver nanoparticles from the extract of Heliotropium eichwaldi L. and their effect as antioxidant, antidiabetic, and anti‐cholinesterase

Abstract

Recently, green nanotechnology has received much importance in different fields. It is concerned with the production of small-size nanoparticles (NPs).It is less toxic to human health and also environmentally benign. Heliotropium eichwaldi (HE) is an herbaceous weed and is widely distributed in Pakistan. The herb is used traditionally for earache, headache, cleaning, and

Synthesis, optimization, and characterization of silver/gold allied bimetallic from Hippeastrum hybridum (L.) and their ex vivo anti‐acetylcholinesterase activity in rat brain

“…The current results are in good accordance with the previous report. [41,42] The present UV results are also supported by Sher et al [9] For the synthesis of unique NPs, an ideal environment is required, for example, pH, plant, reaction time, salt concentrations, temperature, and stability period. A previous report by Qian et al [43] confirmed that different intrinsic factors affect the yield of NPs.…”

“…The FT‐IR Shimadzu (IR Prestige‐21) spectrometer (Japan) analysis of both plant HH and BNPs are shown in Figure 2. The different peaks that are exhibited by HH and their BNPs along with their corresponding phytochemicals and functional groups were confirmed by relating with the standard FT‐IR chart of Sher et al [ 40 ] See Table 1.…”

“…The results are also supported by previous studies. [2,40] An ideal temperature of the reaction medium is also required for unique morphology NPs generation. [48] Therefore, in this study, NPs were synthesized different temperature ranges, that is, 20 C to 100 C. A sharp peak at 542 nm was reported at 40 C, whereas at all other temperatures, the peak becomes broader and absorbance also deviate from the ideal range.…”

“…[8] The green synthesized BNPs showed significant electronic, biomedical, catalytic, and optical potential as correlated to single metal NPs. [4,9] The green synthesis also known as photosynthesis is the generation of NPs via herbal plants as a capping, reducing, and stabilizing ingredient. According to previous studies, these plant phytochemicals like flavonoids, citric acid, phenols, tannins, ascorbic acids, and saponins reduce the metal ions directly to NPs.…”
