“…In North Africa, Atlas Pistachio fruit or leaves decoctions are used traditionally by the local population to treat eye infection or diarrhea [69]. Recent studies emphasized other properties such as antioxidant, antimicrobial, antidiabetic, and antitumor activities [7,57,69,71]. Several studies have been devoted to the effects of bioactives from Pistacia species, including Atlas Pistachio, including gastroprotective and anti-H. pylori activities [4,60].…”

Pistacia atlantica, which belongs to the Anacardiaceae family, is an important species for rural people in arid and semi-arid areas. The fruit, rich in oil, is used in traditional medicine for the treatment of various diseases. The oil extracted from this species growing in a northern area of Algeria and its fatty acid composition were previously studied. However, the largest areas where this species is present (traditional cultivation) is located in southern Algeria. Moreover, studies on oil fatty acid composition and essential oil were always conducted separately. This study was performed in order to assess the fatty acid and volatile organic compound composition of P. atlantica vegetable oil. The seeds were collected randomly from Djelfa (300 km South of Algiers, Algeria). Oil content and fatty acid composition were determined by Soxhlet extraction. The seeds contained high concentrations of oil (32–67%). The major fatty acids were oleic (39–49%), linoleic (23.6–31%), and palmitic (21.3–26.6%) acids. The ratio of polyunsaturated fatty acids (PUFA) to saturated fatty acids (SFA) indicated that the content of unsaturated fatty acids was approximately three times higher than that of SFA. This ratio is widely used in epidemiological studies and research on cardiovascular diseases, diabetes, and metabolic syndrome. The ratios of -acids, i.e., -9/-6 and -6/-3, were 1.3–2 and 18.5–38.3, respectively. Crushed seeds were analyzed by headspace solid-phase microextraction (SPME) coupled with gas chromatography–mass spectrometry. More than 40 compounds were identified, mainly monoterpenes (C10H16), such as α-terpinene and terpinolene, but also sesquiterpenes (C15H24) at lower levels. The value of this species as a source of healthy oil rich in -3 acid and its effects on cardiovascular disease risk are discussed.

“…A great variety of syntheses have been proposed over the years, being the Chloroauric acid HAuCl 4 the most used precursor for colloidal gold. These variations include the use of reducing agents [12], stabilizing agents [13], reaction medium [14], pH control [15], reaction temperature [16], among others. Gold nanoparticles are obtained mainly by a conventional heating method and microwave synthesis [17], being the latter the most studied in recent years, due to short synthesis times and small amounts of reagent.…”

The influence of synthesis method, cycles quantity and sonication time in the gold nanoparticles size and plasmon resonance were analyzed to establish the synthesis with smaller nanoparticle size and higher absorbance. Gold nanoparticles were analyzed by UV-Vis spectrophotometry, dynamic light scattering (DLS) and surface electron microscopy (SEM). The results indicate that the nanoparticles obtained by microwave have bigger size but higher absorption. These nanoparticles were analyzed one year after its synthesis and it was found that the plasmon resonance signal remains almost unchanged. Finally, two equation were derived from the analyzes for estimate molar extinction coefficient, molar concentration and nanoparticle average diameter.

“…The larger gold nanoparticles may be due to the aggregation of the smallest one due to the SEM instrument. The observed nanoparticles were not dispersed effectively due to the colloidal solution and the formation of nano-clusters 36 . The image of SEM showed the circular, rod and spherical shape of NPs with a diameter range of 1 µm various gold NPs 37 .…”

In present work, the gold nanoparticles have been prepared through green synthesis using maize extract at room temperature, the maize extract was used as reducing and stabilizing agents for AuNPs (gold nanoparticles), synthesized gold nanoparticles were confirmed by the color change of the aqueous solution, and the PH of the solution was 7.8, after the confirmation, green gold nanoparticles were characterized through various techniques like UV-Visible spectroscopy, FT-IR (Fourier Transform Infrared Spectroscopy), SEM (Scanning Electron Microscopy), TEM (Transmission Electron Microscopy) and EDAX (Energy Dispersive X-ray analysis). UV-Visible spectroscopy was used to determine the green gold nanoparticles, the absorbance peak was observed at 540 nm with the spherical sized gold nanoparticles, and green gold nanoparticles were also confirmed by TEM, and average particle size of gold nanoparticles was observed 30 nm. FT-IR results represent the various phenolic compounds like alkaloids and flavonoids in aqueous solution. The size, shape and other properties were confirmed through Scanning Electron Microscopy and EDAX analysis. Green synthesis of the gold nanoparticles at room temperature is the innovative process for the various biomedical applications in the field of biomedical science and engineering because of the non-toxic property of the green gold nanoparticles.
