Dalponte Dallabona, Ithiara published the artcileDevelopment of alginate beads with encapsulated jabuticaba peel and propolis extracts to achieve a new natural colorant antioxidant additive, Quality Control of 124-76-5, the main research area is jabuticaba peel propolis extract encapsulation alginate antioxidant additive; Anthocyanins; Plinia cauliflora; Polyphenolics; Scaptotrigona bipunctata.

This work aims to encapsulate anthocyanins and phenolic compounds extracted from a native Brazilian fruit peel – jabuticaba (Plinia cauliflora (Mart.) Kausel) and propolis from Tubuna (Scaptotrigona bipunctata) stingless bees, with great potential benefits for human health. The alginate encapsulation was conducted by the ionotropic gelation through the dripping into the CaCl2 solution Both raw extracts were characterized by TPC – total phenolic content (Folin-Ciocalteu), AA -antioxidant activity (DPPH and ABTS assays), and TMAC – total monomeric anthocyanin concentration (pH differential method); as well as their resultant mixture (2:1 jabuticaba/propolis). The obtained beads presented highly efficient encapsulation of total polyphenols (∼98%) and monomeric anthocyanins (∼89%), with spherical morphol. and smooth surface obtaining a mean diameter between 200 and 250μm. In vitro release study showed that JPE/alginate beads were completely disintegrated at pH 7.4 (intestinal pH), but they were resistant to gastric pH (1.2) presenting a slow release of about 40% in 240 min. This is the first report that encapsulates the mixture of jabuticaba and propolis extracts and may contribute to the utilization of a great source of bioactive compounds besides the potential pigment of anthocyanins, an alternative to natural and healthy food/beverage colorants.

Rys, Magdalena published the artcileBio-Herbicidal Potential of Nanoemulsions with Peppermint Oil on Barnyard Grass and Maize, HPLC of Formula: 124-76-5, the main research area is peppermint oil barnyard grass maize bioherbicidal nanoemulsions; Chlorophyll a fluorescence; Eco-Polysorbate 80; FT-Raman spectroscopy; isothermal calorimetry; phytotoxicity; polydispersity index; relative water content.

Bio-based nanoemulsions are part of green pest management for sustainable agriculture. This study assessed the physicochem. properties and the herbicidal activities of the peppermint essential oil nanoemulsions (PNs) in concentrations 1.0-10% stabilized by Eco-Polysorbate 80 on germinating seeds and young plants of maize and barnyard grass. Based on the design of experiment (DOE) results, the final nanoemulsion formulations were obtained with 1, 1.5, 2, and 5% of essential oil concentration Biol. analyses were conducted to select the most promising sample for selective control of barnyard grass in maize. Seedlings growing in the presence of PNs displayed an overall inhibition of metabolism, as expressed by the calorimetric analyses, which could result from significant differences in both content and composition of carbohydrates. Concentration-response sub estimation showed that leaf-sprayed concentration of PN causing 10% of maize damage is equal to 2.2%, whereas doses causing 50% and 90% of barnyard grass damage are 1.1% and 1.7%, resp. Plants sprayed with PN at 5% or 10% concentration caused significant drops in relative water content in leaves and Chlorophyll a fluorescence 72 h after spraying. In summary, peppermint nanoemulsion with Eco-Polysorbate 80 at 2% concentration is a perspective preparation for selective control of barnyard grass in maize. It should be analyzed further in controlled and field conditions.

Diniz-Silva, Helena Taina published the artcileSurvival of Lactobacillus acidophilus LA-5 and Escherichia coli O157:H7 in Minas Frescal cheese made with oregano and rosemary essential oils, SDS of cas: 124-76-5, the main research area is Lactobacillus Escherichia oregano rosemary essential oil; Dairy products; E. coli O157:H7; Lactobacillus acidophilus; Phenolics.

The effects of the incorporation of the essential oils from Origanum vulgare L.(OVEO; 0.07μL/g) and Rosmarinus officinalis L.(ROEO; 2.65μL/g) in combination in Minas Frescal cheese on the counts of the probiotic Lactobacillus acidophilus LA-5 and Escherichia coli O157:H7 were evaluated during refrigerated storage (7 ± 0.5°C). The terpenes of OVEO and ROEO, survival of the probiotic strain during in vitro digestion, as well as the physicochem. and sensory aspects were also monitored in Minas Frescal cheese. All terpenes decreased in cheese when the storage time increased. The incorporation of OVEO and ROEO delayed the increase in L. acidophilus LA-5 counts in cheese, but did not affect its ability to survive in cheese under simulated gastrointestinal conditions. The decreases in counts of E. coli O157:H7 observed in the first 15 days of refrigerated storage were strongly correlated (r ≥ 0.82) with the terpenes detected in cheese. Scores attributed for aroma, flavor, overall impression and purchase intention of cheese with OVEO and ROEO increased with the increase of the storage time. The incorporation of OVEO and ROEO in combination could be a strategy to control E. coli O157:H7 in probiotic Minas cheese during storage; however, the amounts of these substances should be cautiously selected considering possible neg. sensory impacts in this product.

Lu, Shijun published the artcileInvestigation of vaping fluids recovered from New York State e-cigarette or vaping product use-associated lung injury patients, Quality Control of 124-76-5, the main research area is electronic cigarette vaping fluid product human lung injury; EVALI; cannabis; diluents; electronic cigarettes; pesticides; terpenes; vaping fluid; vitamin E acetate.

E-cigarette or vaping product use-associated lung injury (EVALI) is a serious pulmonary condition that is associated with the extended use of certain vaping products. EVALI was first characterized in the summer of 2019 and has since been reported in all 50 U.S. states. From August 2019 through June 2021, the New York State Department of Health has reported more than 197 confirmed cases emanating from all regions of the state. The Wadsworth Center at the New York State Department of Heath received vaping cartridges recovered from EVALI patients for chem. anal. of their contents. Untargeted anal. methods using gas chromatog.-mass spectrometry and liquid chromatog.-high-resolution mass spectrometry as well as targeted analyses for a variety of analytes including cannabinoids, pesticides, vitamin E acetate (VEA) and mycotoxins were used to characterize the composition of the vaping fluids and several com. vaping fluid additives. From the analyses of the 284 e-cigarette devices recovered from patients, 82 were found to be nicotine-containing pods, and 202 devices containing cannabis oil, apparently from unauthorized or black-market dealers. The fluids from the cannabis-oil cartridges tended to have lower levels of THCs (Δ9-tetrahydrocannabinol + Δ8-tetrahydrocannabinol) and total cannabinoids compared with those of com. produced formulations and contained significant levels of diluents including VEA, medium-chain triglycerides, polyethylene glycol, and castor oil. VEA was the diluent most frequently detected, which was present in 132 (65.3%) of the vaping fluids that contained cannabis oil. When present, VEA ranged from 2.0 to 67.8% of the total mass of the oil with a mean content of 37.0%. In some cases, two or three diluents were detected in the same sample. The ratio of VEA to THCs varied widely, from 0.07 to 5.34. VEA and specifically the high ratios of VEA to THCs in black-market vaping fluids may be causative in EVALI. The safety of addnl. components and additives that are present in vaping fluids are likewise of concern.

Wang, Siyu published the artcileIron-catalyzed borylation and silylation of unactivated tertiary, secondary, and primary alkyl chlorides, Application In Synthesis of 124-76-5, the main research area is tertiary secondary primary alkyl chloride iron catalysis borylation silylation.

Herein, we describe an iron-catalyzed borylation and silylation of unactivated alkyl chlorides, delivering the tertiary, secondary, and primary alkylboronic esters, and secondary, primary alkylsilanes with high efficiency. This protocol exhibits broad substrate scope and good functional group compatibility, allowing the efficient late-stage borylation of biorelevant compounds, thus offering an excellent platform in drug discovery and development. Preliminary mechanistic studies suggest that an alkyl radical was involved in this catalytic system.

Qneibi, Mohammad published the artcileThe neuroprotective role of Origanum syriacum L. and Lavandula dentata L. essential oils through their effects on AMPA receptors, Product Details of C10H18O, the main research area is Origanum Lavandula essential oil neuroprotective AMPA receptor.

Lavandula dentata L. and Origanum syriacum L. essential oils have numerous health benefits and properties, such as possessing common components with a variant degree of depressive actions in the central nervous system. We investigated the depressive property of these oils on AMPA receptors, which are responsible for most of the fast-excitatory neurotransmission in the CNS and play a critical role in synaptic plasticity. Since excessive activation of AMPARs has been linked to neurotoxicity leading to various pathologies, we hypothesize that these oils have a neuroprotective role by acting directly on the kinetics of AMPARs. The current study results showed that the biophys. properties of AMPA receptor subunits showed a decrease in desensitization rate of GluA1 and GluA2 homomers, using O. syriacum, while administering L. dentata oil decreased the desensitization rate of GluA1 and GluA2 homomers, as well as GluA1/2 heteromers. As for the deactivation rate, both oils slowed the deactivation kinetics of all AMPA receptor subunits. Intriguingly, between the two oils, the effect of desensitization and deactivation was of a greater significance for L. dentata oil than O. syriacum. Our data suggest that the two oils contain components that are essential to identify, as those active components underlie the oils’ neuronal depressive properties reported, and to extract them to synthesize a potent neuroprotective drug to treat neurol. diseases potentially.

Vorobyova, Viktoria published the artcileApricot pomace extract as a natural corrosion inhibitor of mild steel corrosion in 0.5 M NaCl solution: a combined experimental and theoretical approach, Safety of rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, the main research area is Primus 2propanol extract steel corrosion inhibitor.

The inhibiting effect of 2-propanol extract of apricot pomace (APE) in respect to mild steel corrosion in 0.5 M NaCl is studied by gravimetric and potentiodynamic polarization methods. The characterization of APE is carried out by Fourier transform IR spectroscopy (FTIR) and gas chromatog.-mass spectrometry (GC-MS) anal. It is found that APE acts as a corrosion inhibitor in chloride-containing media. The maximum inhibiting efficiency (about 98%) is obtained in APE presence of 500 ppm after 40 h immersion. The results of the polarization test reveal that APE acts as a mixed type inhibitor decreasing both the anodic and the cathodic reactions rates. The adsorption of APE on the mild steel surface is investigated by AFM and SEM. DFT simulation calculations support the exptl. results obtained.

Zeliou, Konstantina published the artcileMetabolomic fingerprinting and genetic discrimination of four Hypericum taxa from Greece, HPLC of Formula: 124-76-5, the main research area is Hypericum metabolomic fingerprinting; Essential oil; Flavonoids; Genetic analysis; Hypericaceae; Hypericum spp.; Metabolomics; Multivariate analysis; Naphthodianthrones; Phloroglucinols; Sesquiterpenes; nrITS.

Hypericum perforatum has plenty of uses in traditional medicine and is the source of top-selling herbal drugs and food supplements. The secondary metabolite chem. for most of the nearly 500 Hypericum taxa is still unknown, even though they are used interchangeably. In the present study, we characterized four Hypericum populations from Achaia, Greece, belonging to H. perforatum ssp. veronense, H. perfoliatum, H. triquetrifolium, and an uninvestigated taxon, H. empetrifolium ssp. empetrifolium, in terms of their essential oils and polar bioactives in methanolic extracts via GC-MS, LC-HRMS, LC-DAD-MS, and HPLC-DAD. We also performed sequence anal. of nrITS to explore the genetic profile of these taxa and to examine whether their genotype is correlated to the metabolome. Sixty-three non-volatile compounds, phloroglucinols in their majority, and over one hundred (113) volatiles, mostly sesqui- and mono- terpenes, were detected. The concentration of the major polar constituents varied greatly among samples. In particular, phloroglucinols′ diversity and abundance in H. empetrifolium ssp. empetrifolium was remarkable. The PCA and Biplot anal. revealed the contribution of each compound to the total chemodiversity and also revealed certain compounds that contribute to the discrimination of the samples. Sequence anal. of nrITS revealed different genetic profiles and markers which can be used for the identification of the four Hypericum taxa. The Mantel test showed a relatively strong correlation between the genetic profile and the volatile compounds and low with the main polar metabolites.

Temerdashev, Z. A. published the artcileIdentification and Determination of the Components of Garden Sage (Salvia officinalis L.) Essential Oil, Isolated by Different Extraction Methods, COA of Formula: C10H18O, the main research area is Salvia essential oil camphor alphathujone betathujone hydrodistillation.

We studied the component composition of the essential oil of garden sage (Salvia officinalis L.), obtained by various extraction methods. Essential oils were obtained by hydrodistillation and subcritical CO2 extraction, supercritical fluid extraction, and subcritical extraction with solid-phase and liquid-liquid preconcentration The components were identified by comparing the recorded mass spectra with the spectra of individual compounds and the data of the NIST07 and WILEY8 data bases. For all extraction methods, the major essential oil components were 1,8-cineole, camphor, α-thujone, β-thujone, borneol, 4-terpineol, β-caryophyllene, β-caryophyllene oxide, and viridiflorol. The concentration of analytes in the extracts varied depending on the extraction method. In total, 104 components were identified in the extracts, of which 30 were extracted by hydrodistillation, 32 by subcritical CO2 extraction, 14 by supercritical fluid extraction, 46 and 62 by subcritical extraction with solid-phase and liquid-liquid extraction into the organic phase. An increase in the number of components in more stringent extraction methods as compared to hydrodistillation showed that, in the extracts, a deeper decomposition of macrocomponents might take place, except for camphor.

Abdelsalam, Nader R. published the artcileMorphological, biochemical, molecular, and oil toxicity properties of Taxodium trees from different locations, Quality Control of 124-76-5, the main research area is Taxodium Stophilus essential oil toxicity insecticide.

Taxodium is a deciduous conifer belong to family Cupressaceae, commonly known as cypresses. In the present study, two species of Taxodium trees from four locations in Egypt were investigated. Bald cypress and pond cypress as plant genetic resources were surveyed and tested for horticultural and morphol. traits using biochem. and mol. genetic techniques. Leaf essential oils (EOs) were analyzed by gas chromatog. coupled with mass spectrometry (GC/MS), subjected to bioassay for insecticidal activity against the rice weevil (Sitophilus oryzae L.) and the red flour beetle (Tribolium castaneum (Herbst)), and compared with three monoterpenes (D-limonene, camphor, and carvone). T. distichum var. distichum (bald cypress) growing in the drylands in the Alexandria, El-Beheira, Giza 1, and Qalyubia governorates had lower root hydrogen peroxide (H2O2), proline content, and leaf peroxidase activity than T. distichum var. imbricarium (pond cypress, Giza 2), growing in swamplands of the Giza governorate. Forty random amplified polymorphic DNA (RAPD-DNA) primers and 20 simple sequence repeats (SSRs) indicated 57.41% and 64.50% polymorphism, resp., between the Taxodium species. The main constituents of leaf EOs from trees growing in Alexandria were germacrene D (14.71%), borneol acetate (6.81%), ledene oxide-(II) (6.13%), and trans(β)-caryophyllene (6.13%); thujopsene (18.27%), 3-carene (14.49%), and cedrol (8.02%) were found in trees from Qalyubia; thujopsene (19.93%), α-caryophyllene oxide (17.32%), and cedrol (10.87%) from trees in Giza 1, α-pinene (63.80%) and thujopsene (10.15%) from trees in Giza 2, and El-Beheira α-pinene (26.66%), thujopsene (22.42%), and cedrol (11.30%) in trees from El-Beheira. S. oryzae was more susceptible than T. castaneum to the EOs from leaves of Taxodium trees from the four localities. Taxodium oil from El-Beheira followed by carvone and EOs from trees grown in Alexandria showed the lowest LC50 against S. oryzae with values of < 50, 28.52, and > 50μL/L, resp. Carvone, Taxodium EOs from El-Beheira and Qalyubia exhibited the lowest LC50 against T. castaneum with values of 53.37, 66.40, and 72.54μL/L, resp.
