Gatzias, I. S. published the artcileGeographical differentiation of feta cheese from northern Greece based on physicochemical parameters, volatile compounds and fatty acids, Category: esters-buliding-blocks, the main research area is physicochem property volatile compound fatty acid feta cheese Greece.

The present study aimed to differentiate feta cheese samples produced in northern Greece according to geog. origin. In 2006 the EU, through Council Regulation (EC) 510/2006 succeeded in giving a competitive advantage to the quality and diversity of the Union’s agricultural production by adopting PDO (Protected Designation of Origin) and PGI (Protected Geog. Indication) regulations among EU members. Feta cheese has been approved as a Greek PDO product in 2008. Feta cheese samples from the regions of Ioannina, Arta, Thessaloniki, Larissa and Evros, were subjected to physicochem., fatty acid and volatile compounds analyses. Using multivariate statistical anal. (MANOVA/LDA) and the cross-validation method, cheese samples achieved a correct classification rate of 61.8%, 65.8% and 88.2% based on physicochem. parameters, volatile profile and fatty acid composition, resp. Fatty acids were the most efficient parameters for the differentiation of cheese samples. When all three above parameters were combined the correct classification rate of cheese samples increased to 89.5%.

de Castro, Antonio published the artcileEffect of Spanish-style processing steps and inoculation with Lactobacillus pentosus starter culture on the volatile composition of cv. Manzanilla green olives, COA of Formula: C11H22O2, the main research area is Lactobacillus fermentation volatile compound olive; Lactobacillus pentosus; Manzanilla cultivar; Processing; Table olives; Volatile composition.

The effects of the main steps of Spanish-style processing (alk. treatment and fermentation) on the volatile composition of cv. Manzanilla green olives were studied. Both spontaneous and controlled fermentations were considered. In the latter case, a Lactobacillus pentosus strain from green olive fermentation brine was used as starter culture. The volatile profile was determined by headspace solid-phase microextraction (HS-SPME) combined with gas chromatog.-mass spectrometry (GC-MS). Most of the volatile compounds detected in fresh olives decreased or were undetected after alk. treatment, while several compounds (mostly acetic acid, 2-methylbutanoic acid, and ethanol) were formed as a result of this treatment. Over 50 new volatile components, mostly esters and phenols, appeared as a result of fermentation The most outstanding finding was a considerable increase in 4-Et phenol (almost 100-fold increase) in inoculated olives compared to the uninoculated product. However, a sensory panel did not find significant differences in odor perception.

Barrozo, Mayara Macedo published the artcileRepellent and acaricidal activity of coconut oil fatty acids and their derivative compounds and catnip oil against Amblyomma sculptum, Product Details of C11H22O2, the main research area is Amblyomma sculptum coconut oil fatty acid catnip repellent acaricidal; Acaricidal activity petri dish bioassay; Amblyomma sculptum; Coconut oil; Larval pack bioassay; Repellency.

This study was carried out aiming to evaluate the repellent and acaricidal activity of major ingredient compounds from coconut oil including their Me ester derivatives and catnip oil against nymphs and larvae of Amblyomma sculptum. Repellent candidates, coconut oil free fatty acids (coconut FFA mainly C12, C10 and C8 acid); lauric acid (C12 acid); capric acid (C10 acid); Me laurate; Me caprate and 10% each of C12, C10 and C8 acid (1:1:1) in lavender oil formulation (CFA in lavender formula) and catnip oil (Nepeta cataria), were screened using a Petri dish bioassay to assess repellency. Catnip oil, Me caprate, Me laurate, and CFA in lavender formulation repelled ticks strongly (P lt 0.05) at almost all times evaluated, with an average of 77.8-100% repellency. Some candidate repellents with consistent strong repellence observed were selected for further evaluation, with coconut CFA in lavender formula showing a repellency lasted up to 7 days, while those of catnip oil and Me caprate were active for 4 and 3 days, resp. For the acaricide test, five concentrations (2.5; 5; 10; 15 and 20 mg/mL) were evaluated using the larval packet test. Only CFA in lavender formula and two Me esters showed acaricidal activity, with Me laurate presenting the strongest toxicity at 15 mg/mL concentration, which was effective against more than 93% of the tested larvae. Catnip oil caused no mortality of A. scultptum larvae in all concentrations tested.

Hopkins, Davis H. published the artcileThe molecular basis for the neofunctionalization of the juvenile hormone esterase duplication in Drosophila, Related Products of esters-buliding-blocks, the main research area is Drosophila juvenile hormone esterase neofunctionalization; Juvenile hormone esterase; Neofunctionalization; Odorant degrading enzyme; Structural evolution.

The Drosophila melanogaster enzymes juvenile hormone esterase (DmJHE) and its duplicate, DmJHEdup, present ideal examples for studying the structural changes involved in the neofunctionalization of enzyme duplicates. DmJHE is a hormone esterase with precise regulation and highly specific activity for its substrate, juvenile hormone. DmJHEdup is an odorant degrading esterase (ODE) responsible for processing various kairomones in antennae. Our phylogenetic anal. shows that the JHE lineage predates the hemi/holometabolan split and that several duplications of JHEs have been templates for the evolution of secreted β-esterases such as ODEs through the course of insect evolution. Our biochem. comparisons further show that DmJHE has sufficient substrate promiscuity and activity against odorant esters for a duplicate to evolve a general ODE function against a range of mid-long chain food esters, as is shown in DmJHEdup. This substrate range complements that of the only other general ODE known in this species, Esterase 6. Homol. models of DmJHE and DmJHEdup enabled comparisons between each enzyme and the known structures of a lepidopteran JHE and Esterase 6. Both JHEs showed very similar active sites despite low sequence identity (30%). Both ODEs differed drastically from the JHEs and each other, explaining their complementary substrate ranges. A small number of amino acid changes are identified that may have been involved in the early stages of the neofunctionalization of DmJHEdup. Our results provide key insights into the process of neofunctionalization and the structural changes that can be involved.

Gao, Yadong published the artcileVisible-Light-Induced Nickel-Catalyzed Cross-Coupling with Alkylzirconocenes from Unactivated Alkenes, Computed Properties of 110-42-9, the main research area is alkene alkyl iodide zirconocene nickel photochem regioselective cross coupling; aralkyl chloride alkene zirconocene nickel photochem regioselective cross coupling; aryl iodide alkene zirconocene nickel photochem regioselective cross coupling; unsaturated bromide alkene zirconocene nickel photochem regioselective cross coupling.

Visible-light-induced single nickel-catalyzed C(sp3)-C(sp3), C(sp3)-C(sp2) and C(sp3)-C(sp) cross-coupling reactions were reported using alkylzirconocenes, which were easily generated in-situ from terminal or internal unactivated alkenes through hydrozirconation and chain walking. This method was mild and applicable for a large range of substrates including primary, secondary, tertiary alkyl, aryl, alkenyl, alkynyl halides and a variety of alkenes. Mechanistic studies suggested a novel nickel-catalyzed radical cross-coupling pathway, which represented the first visible-light-induced transformation of alkylzirconocenes.

Park, Hyeon-Yong published the artcileDiscrimination of Platycodon grandiflorum and Codonopsis lanceolata using gas chromatography-mass spectrometry-based metabolomics approach, Application of Methyl decanoate, the main research area is Platycodon Codonopsis metabolomics gas chromatog mass spectrometry traditional medicine; Codonopsis lanceolata; Gas chromatography-mass spectrometry (GC-MS); Metabolite profilings; Multivariate statistical analysis; Platycodon grandiflorum.

Species of herbaceous flowering perennial plant of the family Campanulaceae such as Platycodon grandiflorum (P. grandiflorum) and Codonopsis lanceolata (C. lanceolata) widely used in traditional medicine to treat different diseases. In spite of different medicinal results after consumption of the plants, it is hard to distinguish between two of them, because of their similar morphol. characteristics. In this study, a gas chromatog.-mass spectrometry (GC-MS) – based metabolite profiling approach was performed and examined to discriminate tuberous roots of P. grandiflorum and C. lanceolate for medicinal purposes. Two basic approaches for sample preparation, headspace solid-phase microextraction (HS-SPME) and solvent extraction were adopted. Multivariate statistical techniques, such as orthogonal partial least-squares discriminant anal. (OPLS-DA) plots showed significant differences between P. grandiflorum and C. lanceolata for polar primary and volatile organic metabolites. A number of potential candidates were suggested as the chemomarkers for discrimination of two plants.

Osorio, Pedro R. A. published the artcileEssential oil of Noni, Morinda citrifolia L., fruits controls the rice stem-rot disease without detrimentally affect beneficial fungi and ladybeetles, Product Details of C11H22O2, the main research area is Morinda fruit essential oil.

The use of botanical fungicides has been presented as a promising tool to replace the use of synthetic compounds, as the former seems to offer reduced risks to the environment and human health. Here, we characterized the major constituents and evaluated the potential of essential oils of Noni, Morinda citrifolia L. plants for controlling stem-rot disease caused by the fungus Sclerotium rolfsii Catt in Neotropical rice, Oryza sativa L., fields. Using in silico mol. predictions and toxicol. approaches, we further assessed the essential oil selectivity against beneficial organisms such as the fungi Trichoderma asperellum Samuels, Lieckfeldt & Nirenbeand the ladybeetles Eriopis connexa Germar and Coleomegilla maculata DeGeer. Our results revealed that octanoic acid (64.0 %), butanoic acid (10.2 %), and hexanoic acid (8.6 %) were the major oil components. When applied at 30 mg/mL, the essential oil inhibited mycelial growth, whereas at 10 mg/mL, it inhibited the germination of all S. rolfsii sclerotia. The essential oil application at 25 mg/mL reduced disease severity in both curative (56.4 %) and preventive (71.2 %) methods. Essential oil applications (30 mg/mL) did not affect the beneficial fungus T. asperellum nor did it kill any ladybeetle. Our mol. docking analyses reinforced the essential oil selectivity actions predicting higher potential interactions between its major components and the tyrosine-tRNA ligase of S. rolfsii compared to those of T. asperellum. Collectively, our findings demonstrated that Noni essential oil could control S. rolfsii infestations without causing any detrimental effects on relevant beneficial organisms, highlighting its potential as an alternative fungicide.
