Yu, Zhihui published the artcileComparative analysis of lipid profiles and flavor composition of marinated eggs from different species, Synthetic Route of 140-11-4, the main research area is chicken quail pigeon marinated egg flavor lipid.

This study compared lipid profiles and volatile composition in marinated eggs from different species (chicken, quail, and pigeon) using LC-ESI-MS/MS, and GC-MS, resp. The three marinated eggs showed significant differences in phosphatidylcholine, phosphatidylethanolamine (PE), and neutral lipid profiles of the three marinated eggs. Pigeon-eggs contained the highest content of PE but the lowest content of triglycerides. Seventy-six potential lipid metabolites such as Cer(d18:1/21:0), DG(15:0/18:2), and PE-O(16:1/18:2) were selected for the discrimination of all three groups. Pigeon-eggs contained the highest contents of C18:2 and C22:6, as well as n-3 and n-6 PUFA than quail-eggs and chicken-eggs. Major compounds including 2-Nonanone, 1-Octen-3-ol, and cyclic octaat. sulfur have greatly contributed to the distinction of eggs from different species. The highest levels of aldehydes, acids, and ketones were found in chicken-eggs. This study reported that lipidomic and volatile composition anal. are promising approaches for discriminating of marinated eggs from different species. Novelty impact statement : This is the first study that aiming at comparing the lipid profiles and volatile composition in marinated eggs from different species (chicken, quail, and pigeon) using LC-ESI-MS/MS and GC-MS. Pigeon-eggs contained the highest contents of glycerol phospholipid, n-3, and n-6 PUFA. The predominating volatile compositions of marinated eggs were alcs. aldehydes acids and ketones. Therefore, this study provides a better understanding of the quality of marinated eggs, and help customers to better choose higher nutritional values of marinated eggs.

Parrot, Isabelle published the artcileVolatile Compounds from Flowers of Elaeagnus x submacrophylla Servett.: Extraction, Identification of Flavonoids, and Antioxidant Capacity, Recommanded Product: Benzyl acetate, the main research area is Elaeagnus submacrophylla flavonoid volatile compound extraction antioxidant capacity; Elaeagnus submacrophylla; antioxidants; flavonoids; phenolic content; volatile compounds.

Beneficial to the ecosystem and with significant potential in permaculture, Elaeagnus x submacrophylla Servett. was studied here mainly for the identification of its floral odorants. After olfactory evaluation and determination of the volatile profile of freshly picked flowers by headspace/solid phase microextraction coupled with gas chromatog./mass spectrometry, an ethanolic extract was prepared and investigated for its antioxidant capacity. Unusual mols. were identified in the floral headspace, such as isochavicol or chrysanthemum acetate. The evaluation of the in vitro free radical scavenging capacity (from 0.4 to 1.3 mmol TE/g) and total phenolic content (65.1 mg GAE/g) of the extract pointed out a promising antioxidant activity, potentially related to the identification of several flavonoid glycosides. These results have to be considered in the context of the ever-increasing need to produce innovative natural extracts with notably interesting claims for the cosmetic field.

Gorni, Giacomo published the artcileFabrication of dye-sensitized solar modules based on a prototyping pilot line and their integration into energy storage microsystems, Recommanded Product: Benzyl acetate, the main research area is titania glass frit energy storage microsystem fabrication.

We successfully developed a prototyping pilot line for dye-sensitized solar modules up to 23 × 23 cm2. Dedicated ceramic materials were studied for large area application: we formulated a lead-free glass frit sealant with low softening point based on the ternary system Bi2O3-B2O3-ZnO and a TiO2 anatase screen-printable paste for semi-transparent photoanodes. Alongside traditional screen-printing, specific machines among which a thermal press, a dye injection equipment and an automatic electrolyte filler were designed and realized. A silver-free layout was adopted and the solar modules reached an efficiency close to 2%. Photovoltaic glass panels composed by interconnected DSSC modules were interfaced with custom integrated circuits to realize energy storage microsystems for two self-powered prototypes: a USB solar table for recharging of portable devices and a novel LED glass parapet for active night lighting are here presented.

Lam, Ying-Pong published the artcileAmide/Iminium Zwitterionic Catalysts for (Trans)esterification: Application in Biodiesel Synthesis, Name: Benzyl acetate, the main research area is amide iminium zwitterionic catalyst transesterification dehydrative esterification biodiesel synthesis.

A class of zwitterionic organocatalysts based on an amide anion/iminium cation charge pair has been developed. The zwitterions are easily prepared by reacting aziridines with aminopyridines. They are catalytically applicable to transesterifications and dehydrative esterifications. Mechanistic studies reveal that the amide anion and iminium cation work synergistically in activating the reaction partners, with the iminium cationic moiety interacting with the carbonyl substrates through nonclassical hydrogen bonding. The reaction can be applied to large-scale synthesis of biodiesel under mild conditions.

Gonzalez, Alexandre published the artcileExtraction and Identification of Volatile Organic Compounds in Scentless Flowers of 14 Tillandsia Species Using HS-SPME/GC-MS, Computed Properties of 140-11-4, the main research area is Tillandsia volatile organic compound flower mass spectrometry; PCA analysis; Tillandsia; faint-scented flowers; gas chromatography-mass spectrometry (GC-MS); headspace solid phase microextraction (HS-SPME); heatmap; scentless flowers; volatile organic compounds (VOCs).

VOCs emitted by flowers play an important role in plant ecol. In the past few years, the Tillandsia genus has been scarcely studied according to the VOCs emitted by flowers. Hence, we decided to enlarge the VOCs composition study already undergone in our laboratory on fragrant 3 Tillandsia species to 12 unscented and 2 faint-scented Tillandsia species and hybrids. The headspace solid phase microextraction (HS-SPME) coupled with gas chromatog. combined with the mass spectrometry (GC-MS) method was used to explore the chem. diversity of the VOCs. This study allowed the identification of 65 VOCs among the 14 species and between 6 to 25 compounds were identified in each of the species. The aromatic profile of 10 of the species and hybrids are similar to each other′s and show 8 predominant compounds: benzaldehyde, benzacetaldehyde, hexanol, hexanal, heptanal, octanal, nonanal, and furan-2-pentyl. Some specific compounds are present only in some unique species such as trans-calamenene, α-muurolene, and α-guaiene trans-β-bergamotene. The two faint-scented species studied present an original aromatic profile with a high number of monoterpenes or phenylpropanoids/benzenoids. Our studies allow a better understanding of the ecol. role and function of these VOCs in the interactions between these plants with their environment.

Three novel N-(α-bromoacyl)-α-amino esters: Me 2-(2-bromo-3-methylbutanamido)pentanoate, Me 2-(2-bromo-3-methylbutanamido)-2-phenylacetate and Me 2-(2-bromo-3-methylbutanamido)-3-phenylpropanoate were synthesized. Single crystal X-ray diffraction data are reported for compounds Me 2-(2-bromo-3-methylbutanamido)pentanoate and Me 2-(2-bromo-3-methylbutanamido)-2-phenylacetate. The cytotoxicity, anti-inflammatory and antibacterial activity of compounds bromoacyl amino esters were investigated. Addnl., the physico-chem. properties of studied compounds were calculated and an in silico toxicol. study of compounds the amino esters was performed. The low level of cytotoxicity and absence of antibacterial and anti-inflammatory activity of N-(α-bromoacyl)-α-amino esters in tested concentrations might be a beneficial prerequisite for their incorporation in prodrugs.
