Plant-mediated green synthesis of nanomaterials has been increasingly gaining popularity due to its eco-friendly nature and cost-effectiveness. In the present study, we synthesized silver nanoparticles (AgNPs) by using an aqueous solution Saudi Origanum vulgare L. plant extract as a bioreducing agent. The as-synthesized AgNPs were characterized various microscopic spectroscopic techniques. results indicated formation crystalline face-centered cubic (fcc) AgNPs. Additionally, FT-IR study...
Take your pick: Either enantiomer of either diastereomer substrates bearing adjacent stereogenic centers is accessible through reaction an (R)- or (S)-lithiated carbamate with (S)-boronic ester (see scheme; pin=pinacolate, OCb=substituted carbamate).

The reactions of Hoppe's lithiated carbamates with vinylboranes and boronic esters give allylic boranes/boronic esters, subsequent addition aldehydes provides a new route to enantioenriched homoallylic alcohols high enantiomeric ratios diastereomeric ratios. Specifically, sparteine-complexed trans-alkenyl-9-BBN derivatives followed by gave (Z)-anti-homoallylic in greater than 95:5 er 99:1 dr. However, the special case methyl-substituted carbamate, diamine-free conditions were required...
Freie Wahl: Jedes Enantiomer eines jeden Diastereomers von Substraten mit benachbarten stereogenen Zentren ist über die Reaktion (R)- oder (S)-lithiierten Carbamats einem bzw. (S)-Boronsäureester zugänglich (siehe Schema, pin=Pinacolat, OCb=Carbamat-Gruppe).
The essential oil and aqueous distillate composition of Origanum vulgare L. were analyzed by GC/MS. Sixty-seven different components detected in both oils. Sixty-four characterized for the derived from aerial parts, whereas thirty-three volatile distillates O. L., representing 99.8% 98.5% oils, respectively. main parts carvacrol (70.2 ± 1.37%), γ-terpinene (5.6 0.11%), p-cymene (4.5 0.42%), trans-sabinene hydrate (3.8 0.07%), thymol (2.2 0.12%). In comparison, compounds (92.5 0.97%), (2.5...
Essential oils (EOs) from the stems and leaves of Origanum vulgare L. grown in Saudi Arabia Jordan were analyzed by gas chromatography-mass spectrometry (GC-MS) GC-flame ionization detector (FID) techniques on two different columns (polar nonpolar). A detailed phytochemical analysis led to identification 153 constituents these essential oils. Both Jordanian plants are classified chemotypes rich cymyl-compounds. However, contains carvacrol as major component is, thus, characterized a...
Renewed COVID-19 outbreaks, stemming from the highly infectious Delta and Omicron variants, prompted rising fears of a 'pandemic among unvaccinated'. To address this prevalent vaccination crisis, media framing communication strategies can amplify scientific evidence on vaccines to reach diverse geographic socio-economic communities. The critical role engage encourage large populations regarding vaccine acceptance has been rarely studied, despite growing hesitancy. present study used...
The aim of the current study was to explore preservative effect aqueous coriander extract and butylated hydroxytoluene (BHT) on shelf life refrigerated chicken patties for 9 days. For this purpose, BHT (100 ppm) (1%) applied improve storage stability. were evaluated their physiochemical characterization including total phenolic content (TPC), thiobarbituric acid reactive substances (TBARS), peroxide value (PV), carbonyl, metmyoglobin, instrumental color, microbial analysis (total plate...
Crystalline zinc oxide (ZnO) thin films with highly preferential c-axis-oriented crystals were prepared using the reactive e-beam evaporation technique. Prior to deposition, ZnO targets from (99.999%) powder. Post-deposition thermal annealing was performed at various temperatures ranging 200 700 °C for 2 h in air investigate effect of on structural and optical properties. Structural characterization including that crystal structure, orientation, phase, stress, strain, grain size surface...
The volatile chemical constituents derived from two Asteraceae species (Artemisia judaica and A. herba-alba) were analyzed compared for the first time using gas chromatography techniques (GC–MS, GC–FID, Co-GC, LRI determination, database literature searches) on different stationary phase columns (polar nonpolar). This analysis led to identification of a total 110 81 components whole plant (stems, leaves flowers) oils herba-alba respectively. major classes compounds in both plants included...
The chemical components of essential oils derived from leaves and flowers Lantana camara growing in Saudi Arabia are analyzed for the first time using gas chromatography techniques (GC–MS, GC–FID, Co-GC, LRI determination, database literature searches) on two different stationary phase columns (polar nonpolar). This analysis led to identification total 163 compounds oils. 134 were identified oil obtained L. camara, whereas 127 flowers; these account 96.3% 95.3% composition, respectively....

Cholinesterases (ChEs) play a vital role in the regulation of cholinergic transmission. The inhibition ChEs is considered to be involved increasing acetylcholine level brain and thus has been implicated treatment Alzheimer's disease. We have designed synthesized series novel indole derivatives screened them for acetylcholinesterase (AChE) butyrylcholinesterase (BChE). Most tested compounds exhibited inhibitory activity against AChE BChE. Among 4f 6e showed highest with IC50 91.21±0.06...
Plant extracts have shown promising corrosion inhibitive actions for different metals in diverse corrosive climate. In numerous studies, it has been demonstrated that features of plant are due to the presence complex mixtures phytomolecules their composition. However, rare efforts made identify those accountable activity extracts. Therefore, this paper, several Matricaria aurea were prepared and assessed anticorrosive mild steel (MS) media (1.0 M HCl). Among tested extracts, methanolic...
