“…In addition, assessment of the optimal concentration among different extract concentrations has shown that increasing the extract concentration will augment nanoparticle synthesis. On the other hand, increasing the concentration of silver nitrate solution has increased nanoparticle synthesis rate, as well [ 33 ]. In general, when the volume of the extract increases under constant conditions, more organic material surrounds the nanoparticles.…”

“…In FTIR spectroscopy, oxygenated compounds present in the alcoholic and phenolic substances of the extract act as one of the active stabilizing agents to reduce silver nanoparticles [ 33 ]. Although the exact mechanism of nanoparticle formation during green synthesis is not yet known, it seems that terpenoids, sugars, phenols, and other plant extract compounds can be used in the synthesis of metal nanoparticles [ 38 ].…”

Objective. Vaccinium genus plants have medicinal value, of which Vaccinium arctostaphylos (Caucasian whortleberry or Qare-Qat in the local language) is the only available species in Iran. Public tendency to use herbal remedies and natural products such as synthesized nanoparticles is increasing due to the proof of the destructive side effects of chemical drugs. Nanosilver products have been effective against more than 650 microbe types. This study was aimed at assessing the possibility of green synthesis of silver nanoparticles using Vaccinium arctostaphylos aqueous extract and at evaluating its antibacterial properties, as well. Materials and Methods. In order to synthesize silver nanoparticles, different volumes of Vaccinium arctostaphylos aqueous extract (3, 5, 10, 15, and 30 ml) were assessed with different silver nitrate solution concentrations (0.5, 1, 3, 5, and 10 mM) and different reaction time durations (1, 3, 5, 10, and 20 minutes) at room temperature using a rotary shaker with a speed of 150 rpm. Ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction analysis (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM) were carried out. The antibacterial activity of the aqueous extract and the synthesized nanoparticles was evaluated, as well. Results. Silver nanoparticle formation process was confirmed with XRD analysis, transmission electron microscopy (TEM), and FTIR spectroscopy. The UV-Vis spectroscopy of silver colloidal nanoparticles showed a surface plasmon resonance peak at 443 nm under optimal conditions (3 ml aqueous extract volume, 1 mM silver nitrate solution concentration, and 3 min reaction time under sunlight exposure). The reduction of silver ions to silver nanoparticles in solution was confirmed, as well. Based on X-ray diffraction analysis, the size of silver nanoparticles was in the range of 7-16 nm. TEM images showed an even distribution of silver nanoparticles, with a spherical shape. FTIR spectroscopy demonstrated the presence of different functional groups of oxygenated compounds such as carboxyl, hydroxyl, and nitrogenous groups. The antibacterial properties of the synthesized nanoparticles were confirmed. Conclusion. The synthesized nanoparticles showed more antibacterial properties against gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus) than gram-negative ones (Escherichia coli and Salmonella enteritidis).

A simple, facile and rapid microwave irradiated system was applied to synthesize silver nanoparticles using 'Golden Delicious' apple pulp (Malus domestica) and cumin (Cuminum cyminum) seed extracts. The phytosynthesized AgNPs were characterized by Ultraviolet–Visible Spectroscopy (UV–vis), Fourier transform infrared (FTIR), X-ray Diffraction (XRD) Transmission Electron Microscopy (TEM) and Zeta sizer analysis. In the study, the presence of face-centered cubic crystalline structured metallic silver in AgNPs from apple and cumin extracts and the monodisperse nature of AgNPs with the size distribution range of 5.46–20 nm and 1.84–20.57 nm were confirmed, respectively. This study established an efficient green synthesis approach that created so far, the smallest silver nanoparticles by using these two extracts. According to the results obtained, AgNPs synthesized using both extracts were non-toxic against L929 mouse fibroblast cells, while they were effective against both Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria with a greater effect on S. aureus. Moreover, AgNPs synthesized through cumin extract exhibited a higher ABTS scavenging ability (96.43 ± 0.78% at 160 μg/mL) in comparison to apple pulp extract mediated AgNPs, while both AgNPs showed lower activity for DPPH (27.84 ± 0.56% and 13.12 ± 0.32% from cumin seed and apple pulp extracts, respectively). In summary, our results suggest the green non-cytotoxic AgNPs synthesized in this study could be a promising template for further biological and clinical applications. Graphical abstract

The use of plants for medicinal purposes is performed empirically by traditional knowledge with the use of preparations that seek to extract their active principles, and are considered to be fundamental to human health. In this context, the aim of the present study was to of this study was to carry out a systematic review of the biological activities of the Arecaceae family distributed throughout Brazil. This research was carried out through a comprehensive search using the following databases, Scopus, Portal Periódicos Capes, PubMed, Google Scholar and Science Direct, using the following descriptors: “Arecaceae” and “Biological properties of the family Arecaeae”, checked at <www.theplantlist.org/> to check synonyms. It was possible to identify numerous biological activities in the arecaceae family, among the most recurring ones, the antioxidant, antimicrobial and anti-inflammatory activity. These activities are justified by the presence of fatty acids, phenolic compounds, alkaloids and terpenes. Studies routinely report lauric acid as a major in the plants of this family, which makes it a potential compound to cure or assist in the treatment of various diseases.
