“…The ligands were synthesized according to a previously published method. 4, 29 1 mmol of aryl chloride (m-or pchlorobenzoyl chloride) dissolved in anhydrous acetone was added to the potassium thiocyanate solution (1.1 mmol) in anhydrous acetone and, then the resulting mixture was stirred under reflux for half an hour. After the mixture was cooled to room temperature, a diethylamine solution (1.1 mol) in anhydrous acetone was added dropwise over a period of 15-20 min.…”

Four ruthenium complexes {[RuCl(CO)(PPh 3 ) 2 L 1 ], [RuCl(CO)(PPh 3 ) 2 L 2 ],[RuCl 2 (PPh 3 ) 2 L 1 ] and [RuCl 2 (PPh 3 ) 2 L 2 ]} supported with N-acylthiourea-based ligands were synthesized. The compounds prepared were characterized by 1 H NMR, 13 C NMR, elemental analysis, UV-vis, and magnetic susceptibility methods. The characterization of the molecular structure of two ruthenium complexes {[RuCl(CO)(PPh 3 ) 2 L 1 ] and [RuCl 2 (PPh 3 ) 2 L 1 ]} was also performed using the single crystal X-ray diffraction method. Single crystal X-ray analyses indicates the existence of different non-covalent interactions between different parts of the molecules, which led to the formation of three-dimensional supramolecular architectures and synthons. The magnetic susceptibility and UV-vis spectra of the prepared ruthenium complexes propose that they are of low-spin states, where Ru(II) is d 6 and Ru(III) is d 5 low spin. These ruthenium compounds functioned as catalysts for the NaBH 4 -mediated reduction of various nitro compounds. The catalytic results show that the [RuCl 2 (PPh 3 ) 2 L] type complexes exhibit higher catalytic activity than the [RuCl(CO)(PPh 3 ) 2 L] type complexes, and [RuCl 2 (PPh 3 ) 2 L 1 ] has high catalytic selectivity and efficiency in a short time (>99 yield with catalyst loading 0.01 mol in 0.5 h). Furthermore, the catalytic activity of [RuCl 2 (PPh 3 ) 2 L 1 ] was investigated using nitrobenzene as a model substrate to understand the reaction pathway, and this study proved that this nitro reduction proceeds via a direct pathway, with the formation of N-hydroxylamine as the main intermediate followed by the occurrence of aniline.

“…Olmedo et al found that camphor (35.70 g/100 g) was the most important component in REO, followed by verbenone (26.20 g/100 g) and b-caryophyllene (15.80 g/100 g) (24). In addition, another study showed that rosemary oil contains 45 volatile compounds, and eucalyptol (1,8-cineole) was the most abundant (33.15%), followed by camphor (10.31%), α-pinene (8.11%), isocaryophyllene (7.02%), bornyl acetate (5.66%), α-terpineol (4.92%), and camphene (4.22%), while differences in geographic location [30] may explain the differences between our study and previous studies. Generally, the natural antioxidant properties are mainly attributed to their phenolic contents; thus, their antioxidants action is like synthetic phenolic antioxidants [31].…”

The popularity of rosemary has grown as a natural alternative over the synthetic supplements due to its potential health benefits. The rosemary plant has been utilized to preserve food due to its ability to prevent oxidation and microbial contamination. The reason for this study was to determine the phytochemical components and antimicrobial activity of rosemary essential oil (REO) and the effect of REO addition (0.5 and 0.7%) on the chemical, microbiological, and sensory properties of stirred-like yogurt (SLY) during 16 days of storage at 4 °C. The obtained data observed that REO exhibited antimicrobial action against Escherichia coli, Staphylococcus aureus, and Salmonella marcescens, as well as fungi (Aspergillus flavus) and yeasts (Candida albicans). Increased REO to 0.7% accelerated (p < 0.05) the development of lactic acid bacteria (LAB) in SLY (8.3 log cfu/g) and delayed yeast growth up to 12 days. Molds and coliforms were also not found in the SLY samples with REO. In comparison to control samples, sensory results showed that the addition of REO improves the overall acceptance of SLY (p < 0.05). In conclusion, the current study found that REO could be used as a natural preservative during the production of SLY to extend shelf-life and promote LAB development.
