Heracleum persicum Desf. ex Fischer seeds are a rich source of essential oils (EOs) with high antimicrobial and antioxidant effects. In order to determine the phytochemical variability in various Iranian H. persicum populations, seed samples were collected from 10 different climatic locations. The current study indicated that hexyl butyrate (20.9-44.7%), octyl acetate (11.2-20.3%), hexyl-2-methylbutyrate (4.81-8.64%), and octyl 2-methyl butyrate (3.41-8.91%) were the major components of the EOs. The maximum (44.7%) and the minimum (20.9%) content of hexyl butyrate were obtained from Kaleibar and Sari populations, respectively. Moreover, the octyl acetate content ranged from 2% (in Mahdasht) to 20.3% in Torghabeh population. The CA and PCA analysis divided the 10 Iranian H. persicum populations into three major groups. Populations from Khanghah, Kaleibar, Shebeilo, Showt, Mahdasht, and Amin Abbad showed a distinct separation in comparison with the other populations, having high contents of hexyl butyrate (39.8%) and low contents of octyl acetate (13.5%) (Chemotype II). According to correlation analysis, the highest correlation coefficient was among habitat elevation and hexyl butyrate content. In addition, the mean annual precipitation was negatively correlated with the content of hexyl butyrate. Although octyl acetate content showed high correlation with soil EC and mean annual temperature, it was not statistically significant. In general, in order to have plants with a high content of hexyl butyrate, it is recommended to harvest these plants from regions with high altitude and low rainfall such as Kaleibar. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Electric Literature of C10H20O2).

Octyl acetate (cas: 112-14-1) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Electric Literature of C10H20O2

Advanced treatment of wet-spun acrylic fiber manufacturing wastewater using three-dimensional electrochemical oxidation was written by Zheng, Tianlong;Wang, Qunhui;Shi, Zhining;Fang, Yue;Shi, Shanshan;Wang, Juan;Wu, Chuanfu. And the article was included in Journal of Environmental Sciences (Beijing, China) in 2016.COA of Formula: C9H16O4 The following contents are mentioned in the article:

A three-dimensional electrochem. oxidation (3D-EC) reactor with introduction of activated carbon (AC) as particle micro-electrodes was applied for the advanced treatment of secondary wastewater effluent of a wet-spun acrylic fiber manufacturing plant. Under the optimized conditions (c.d. of 500 A/m², circulation rate of 5 mL/min, AC dosage of 50 g, and chloride concentration of 1.0 g/L), the average removal efficiencies of COD (COD_cry), NH₃-N, total organic carbon (TOC), and UV absorption at 254 nm (UV₂₅₄) of the 3D-EC reactor were 64.5%, 60.8%, 46.4%, and 64.8%, resp.; while the corresponding effluent concentrations of COD_cry, NH₃-N, TOC, and UV₂₅₄ were 76.6, 20.1, and 42.5 mg/L, and 0.08 Abs/cm, resp. The effluent concentration of COD_cry was less than 100 mg/L, which showed that the treated wastewater satisfied the demand of the integrated wastewater discharge standard (GB 8978-1996). The 3D-EC process remarkably improved the treatment efficiencies with synergistic effects for COD_cry, NH₃-N, TOC, and UV₂₅₄ during the stable stage of 44.5%, 38.8%, 27.2%, and 10.9%, resp., as compared with the sum of the efficiencies of a two-dimensional electrochem. oxidation (2D-EC) reactor and an AC adsorption process, which was ascribed to the numerous micro-electrodes of AC in the 3D-EC reactor. Gas chromatog. mass spectrometry (GC-MS) anal. revealed that electrochem. treatment did not generate more toxic organics, and it was proved that the increase in acute biotoxicity was caused primarily by the production of free chlorine. This study involved multiple reactions and reactants, such as Ethyl methyl adipate (cas: 18891-13-9COA of Formula: C9H16O4).

Ethyl methyl adipate (cas: 18891-13-9) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Abstract: Coffee is one of the most important commodities worldwide. The industrial processing of coffee cherries generates a considerable volume of byproducts such as wastewater, coffee pulp, mucilage, and husk. These byproducts have sugars and nutrients that can be converted into value-added products via microbial action. In this study, for the first time, we evaluated the potential of coffee pulp and coffee wastewater as substrate for alc. fermentation produce a distilled beverage. The must composed by dry or wet coffee pulp and coffee wastewater added of com. sucrose or sugarcane molasses was fermented by S. cerevisiae. After a screening step, a larger fermentation was carried out with the wet pulp added of sucrose due to its higher alc. fermentation efficiency. The distilled beverage contained 38% (volume/volume) ethanol and 0.2 g/L of acetic acid. The contaminants furfural, hydroxymethylfurfural and Et carbamate were below detection level. Among the 48 volatile compounds detected, the majority (21) were Et esters usually associated with floral and sweet aromas. Et decanoate (996.88μg/L) and Et dodecanoate (1088.09μg/L) were the most abundant esters. Coffee spirit presented taste acceptance of 80% and sugarcane spirit, 70%. The tasters indicated an aroma acceptance of 86% for the coffee spirit and 78% for the sugarcane spirit. The results of this work demonstrate the potential for using coffee byproducts to produce a good quality distilled beverage. Considering our results, especially sensorial anal., we can infer that the produced coffee beverage represents a new alternative for adding value to the coffee production chain. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Related Products of 2198-61-0).

Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Related Products of 2198-61-0

Partial least square and k-nearest neighbor algorithms for improved 3D quantitative spectral data-activity relationship consensus modeling of acute toxicity was written by Stoyanova-Slavova, Iva B.;Slavov, Svetoslav H.;Pearce, Bruce;Buzatu, Dan A.;Beger, Richard D.;Wilkes, Jon G.. And the article was included in Environmental Toxicology and Chemistry in 2014.SDS of cas: 763-69-9 The following contents are mentioned in the article:

A diverse set of 154 chems. that included US Food and Drug Administration-regulated compounds tested for their aquatic toxicity in Daphnia magna were modeled by a 3-dimensional quant. spectral data-activity relationship (3D-QSDAR). Two distinct algorithms, partial least squares (PLS) and Tanimoto similarity-based k-nearest neighbors (KNN), were used to process bin occupancy descriptor matrixes obtained after tessellation of the 3D-QSDAR space into regularly sized bins. The performance of models utilizing bins ranging in size from 2 ppm × 2 ppm × 0.5 Å to 20 ppm × 20 ppm × 2.5 Å was explored. Rigorous quality-control criteria were imposed: 100 randomized 20% hold-out test sets were generated and the average R²_test of the resp. models was used as a measure of their performance, and a Y-scrambling procedure was used to identify chance correlations. A consensus between the best-performing composite PLS model using 0.5 Å × 14 ppm × 14 ppm bins and 10 latent variables (average R²_test = 0.770) and the best composite KNN model using 0.5 Å × 8 ppm × 8 ppm and 2 neighbors (average R²_test = 0.801) offered an improvement of about 7.5% (R²_{test consensus} = 0.845). Projection of the most frequently occurring bins on the standard coordinate space indicated that the presence of a primary or secondary amino group-substituted aromatic systems-would result in an increased toxic effect in Daphnia. The presence of a second aromatic ring with highly electroneg. substituents 5 Å to 7 Å apart from the first ring would lead to a further increase in toxicity. Environ Toxicol Chem 2014;33:1271-1282.

Volatolomics approach by HS-SPME-GC-MS and multivariate analysis to discriminate olive tree varieties infected by Xylella fastidiosa was written by Mentana, Annalisa;Camele, Ippolito;Mang, Stefania M.;De Benedetto, Giuseppe E.;Frisullo, Salvatore;Centonze, Diego. And the article was included in Phytochemical Analysis in 2019.Safety of Methyl heptanoate The following contents are mentioned in the article:

Xylella fastidiosa (Xf) is a pathogenic bacterium that causes diseases in olive trees. Therefore, anal. methods for both the characterization of the host/pathogen interaction and infection monitoring are needed. Volatile organic compounds (VOCs) are emitted by plants relate to their physiol. state, therefore VOCs monitoring can assist in detecting stress or infection states before visible signs are present. In this work, the headspace-solid phase microextraction-gaschromatog.-mass spectrometry (HS-SPME-GC-MS) technique was used for the first time to highlight VOCs differences between healthy and Xf-infected olive trees. VOCs from olive tree twig samples were extracted and analyzed by HS-SPME-GC-MS, and hence identified by comparing the exptl. linear retention indexes with the reference values and by MS data obtained from NIST library. Data were processed by principal component anal. (PCA) and anal. of variance (ANOVA). The HS-SPME step was optimized in terms of adsorbent phase and extraction time. HS-SPME-GC-MS technique was applied to the extraction and anal. of VOCs of healthy and Xf-infected olive trees. More than 100 compounds were identified and the differences between samples were evidenced by the multivariate anal. approach. The results showed the marked presence of Me esters in Xf-infected samples, suggesting their probable involvement in the mechanism of diffusible signal factor. The proposed approach represents an easy and solvent-free method to evaluate the presence of Xf in olive trees, and to evidence volatiles produced by host/pathogen interactions that could be involved in the defensive mechanism of the olive tree and/or in the infective action of Xf.

Development of a method based on thermal desorption-gas chromatography/mass spectrometry for the determination of 103 volatile organic compounds in mattresses was written by Cao, Shurui;Wen, Yao;Xi, Cunxian;Li, Xianliang;Zhang, Lei;Wang, Guomin;Shang, Jingchuan. And the article was included in International Journal of Environmental Analytical Chemistry in 2020.Formula: C7H14O3 The following contents are mentioned in the article:

A sensitive and reliable method based on environment test chamber coupled with thermal desorption and gas chromatog.-mass spectrometry (ETC-TD-GC/MS) was developed and validated for the determination of 103 volatile organic compounds (VOCs) emitted from mattresses. In the study, two com. sorbent tubes were compared in terms of adsorption efficiency towards the target analytes. The result illustrated that the multisorbent tubes containing Carbopack C, Carbopack B and Carboxen 1000 had better performance than Tenax TA tubes owing to their large surface area, low capacity for water and high temperature stability, which allowed a wide range of VOCs to be absorbed, especially for VOCs with low b.ps. and small mols. To achieve the optimum conditions for the anal., several thermal desportion parameters were accurately investigated. Under the optimal conditions, the method showed good linearities, with correlation coefficients ranging from 0.9982 to 0.9999 and the method detection limits and method quantification limitsfor target compounds in the range of 0.006 ∼ 0.561μg/m³ and 0.020 ∼ 1.870μg/m³, resp. In order to evaluate the performance of the developed method on real samples, various mattresses from different manufacturers were analyzed. All mattress samples were found to emit VOCs and the values of area-specific emission rate (SERs) for total target compounds were in the range of 90.25 ∼ 288.63μg/m²·h. Moreover, the SERs of VOCs were influenced by the type of sponge materials and mattress fabric layers. The study demonstrated that the method is sensitive, accurate and well-suited for the determination of VOCs emitted from mattresses.

A modified Patel-Teja cubic equation of state. Part II: Parameters for polar substances and its mixtures was written by Forero G., Luis A.;Velasquez J., Jorge A.. And the article was included in Fluid Phase Equilibria in 2014.Recommanded Product: 763-69-9 The following contents are mentioned in the article:

In this work, the parameters of the equation of state formed by the Patel-Teja pressure-volume-temperature relationship and the alpha function of Heyen have been estimated for 184 polar substances. To obtain the parameters of the proposed model, pseudo-exptl. data have been generated using the DIPPR correlations for vapor pressure and liquid d. The proposed model in conjunction with the Wong-Sandler mixing rules and the NRTL activity model have been used to describe the vapor liquid equilibrium of some complex mixtures Three kinds of binary systems have been analyzed and they are those of the type: polar substance/aromatic, polar substance/n-alkane and polar substance/n-alkanol. Based on the homologous series concept, generalized expressions for the binary interaction parameters in the Wong-Sandler-NRTL mixing rules were developed in order to correlate vapor-liquid equilibrium at low pressures for the selected mixtures For n-alkanes and aromatic compounds, the acentric factor has been used to generalize the binary interaction parameters for mixtures with a polar substance and these kinds of compounds In the case of systems composed by a polar substance and an alc., the reduced dipole moment of the alcs. is used to develop the generalized expressions. Ninety-two binary mixtures were analyzed and a relative average absolute deviation of 1.21% was estimated for the bubble pressure. Finally, the model was validated by predicting binary vapor-liquid equilibrium at high pressures and for ternary mixtures In both cases, the results are satisfactory. The average absolute deviations in bubble pressure are 2.34% for high pressure predictions and 1.15% for ternary mixtures This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Recommanded Product: 763-69-9).

Melia azedarach is a common tree used in the traditional medicine of Nepal. In this work, leaves were considered as source of bioactive constituents and composition of methanol extract was evaluated and compared with starting plant material. Flavonoid glycosides and limonoids were identified and quantified by HPLC-DAD-MSn approaches in dried leaves and methanolic extract, while HPLC-APCI-MSn and GC/MS anal. were used to study phytosterol and lipid compositions β-Sitosterol and rutin were the most abundant constituents. HPLC-APCI-MSn and HPLC-DAD-MSn anal. revealed high levels of phytosterols and flavonoids in methanolic extract accounting 9.6 and 7.5% on the dried weight, resp. On the other hand, HPLC/MSn data revealed that limonoid constituents were in minor amount in the extract <0.1%, compared with leaves (0.7%) indicating that degradation occurred during extraction or concentration procedures. The methanol extract was subjected to different bioassays, and antioxidant activity was evaluated. Limited inhibitory activity on acetyl and butyryl cholinesterase, as well as on amylase were detected. Moreover, tyrosinase inhibition was significant resulting in 131.57±0.51 mg kojic acid equivalent/g of dried methanol extract, suggesting possible use of this M. azedarach extract in skin hyperpigmentation conditions. Moderate cytotoxic activity, with IC50 of 26.4μg/mL was observed against human ovarian cancer cell lines (2008 cells). Our findings indicate that the Nepalese M. azedarach leaves can be considered as valuable starting material for the extraction of phenolics and phytosterols, yielding extracts with possible cosmetic and pharmaceutical applications.

Variability in volatile composition of crimson seedless (vitis vinifera) in association with maturity at harvest was written by Maoz, Itay;Kaplunov, Tatiana;Beno-Mualem, Dlila;Lewinsohn, Efraim;Lichter, Amnon. And the article was included in American Journal of Enology and Viticulture in 2018.COA of Formula: C8H16O2 The following contents are mentioned in the article:

Crimson Seedless is a popular table grape cultivar worldwide because of its appearance, balanced sugar and acidity, and excellent texture. In this study, we assessed variability of volatile compounds in berries among different vineyards and explored its association to maturity at harvest. Volatile composition of Crimson Seedless was analyzed in berries sampled from six vineyards in two adjacent regions. The volatile composition consisted of 43 compounds that were identified in all vineyards tested, and 12 compounds showed variable patterns. This anal. enables differentiation between vineyards based on location of the vineyard, berry acidity, or total soluble solids (TSS), but not according to berry weight To eliminate environmental or horticultural effects, berries from another vineyard were separated by d. into categories of higher and lower maturity (>17.5 Brix and <16.0 Brix, resp.). Clear differences were observed among the volatiles of the two berry groups, corresponding in large part to the pattern observed among the vineyards. Many volatile compounds derived from fatty acid metabolism increased, but linolenic acid derivatives decreased, in association with TSS. Among the volatile compounds identified from the seven vineyards, 1-octanol, Me hexanoate, and l-octen-3-ol were associated with higher TSS levels, and (E)-2-hexenal was associated with lower TSS levels. In conclusion, while regional conditions affect berry composition, maturity at harvest is a major, well-defined factor that can account for the observed variability. Compounds that accumulate or decrease in mature berries may serve as addnl. markers for assessing table grape maturity.

Establishment of the volatile signature of wine-based aromatic vinegars subjected to maceration was written by Perestrelo, Rosa;Silva, Catarina L.;Silva, Pedro;Camara, Jose S.. And the article was included in Molecules in 2018.Computed Properties of C7H14O3 The following contents are mentioned in the article:

The flavoring of vinegars with aromatic fruits and medicinal herbs is a practice with increasing trend mostly in countries with oenol. tradition, resulting in a product of improved quality and consumer attractiveness. This study was directed towards the evaluation of the impact of the maceration process on the volatile signature of wine-based aromatic vinegars (WBAVs). The evaluation was performed using solid phase microextraction (SPME) combined with gas chromatog. combined with mass spectrometry (GC-MS). Exptl. parameters influencing headspace solid (HS)-SPME extraction efficiency, were optimized using an univariate exptl. design. The best results were achieved using a polydimethylsiloxane (PDMS) fiber, 10 mL of vinegar sample, at 50 °C for 30 min of extraction This way One hundred and three volatile organic compounds (VOCs), belonging to different chem. families including Et esters (37), higher alcs. (20), fatty acids (10), terpenoids (23), carbonyl compounds (six), lactones (five) and volatile phenols (two), were identified in wine vinegar (control) and WBAV. As far as we know, 34 of these VOCs are reported for the first time in macerated vinegars. Higher alcs. and lactones are the major chem. families in WBAV macerated with apple, whereas terpenoids are predominant in WBAV macerated with banana. The obtained data represent a suitable tool to guarantee the authenticity and genuineness of WBAV, as well as to promote the production of WBAV with improved sensorial and organoleptic properties. To the best of our knowledge, there are no reported studies dealing with the volatile signature of WBAV enriched with banana, passion fruit, apple and pennyroyal.
