Tobacco flavors increase the attractiveness of a tobacco brand and ultimately promote addiction. Information about what flavor and how much flavor is in flavor capsules can provide an effective way to regulate tobacco flavor. In this study, 128 flavor chems. were identified and quantified by gas chromatog.-mass spectrometry using libraries and authentic standards Validation of the developed method was performed for interference, detection limits, calibration curves, accuracy, and precision. Menthol was the main ingredient in all capsules, and the carcinogenic pulegone was detected. Detected menthofuran, benzyl alc., geraniol, and eugenol cause toxic or severe irritation, and detected lactones can increase nicotine addiction by inhibiting nicotine metabolism in smokers. Margin of exposures for carcinogenic pulegone and non-carcinogenic menthol were well below safety thresholds, indicating a significant risk of inhalation exposure. It is desirable to prohibit the use of flavor capsules in consideration of human risk.

Cheng, Huan published the artcileComparison and evaluation of aroma-active compounds for different squeezed Chinese bayberry (Myrica rubra) juices, Recommanded Product: Methyl 3-phenyl-2-propenoate, the publication is Journal of Food Processing and Preservation (2021), 45(11), e15924, database is CAplus.

Chinese bayberry is one of the most valuable fruits with unique flavor in China. Juice aroma can be affected by processing methods, especially squeezing. The present study aimed to differentiate the aroma profiles of bayberry juices under 4 squeezing conditions (freshly/frozenly squeezed at room temperature/4°C). A total of 66 volatiles and 25 active aroma were identified as “green,” “floral,” “fruity” and “woody” odor. The contents of volatiles, including aldehydes, alcs., and esters in the freshly squeezed groups were significantly higher than frozenly squeezed groups. It was found juices squeezed at room temperature had “fermented” flavor. The total content of volatiles in frozenly squeezed at room temperature was the lowest, especially β-caryophyllene and humulene. By using GC-MS-O combined with principal component anal., the bayberry juice freshly squeezed at 4°C was of the best flavor quality, which would be used as optimal condition for squeezing process of bayberry fruits. Novelty impact statement : This work further investigates the effect of 4 different squeezing conditions on volatile aroma compounds of bayberry juice. According to the results of GC-MS-O combined with principal component anal., the contents of volatiles, including aldehydes, alcs., and esters in the freshly squeezed groups, were significantly higher than frozenly squeezed groups, and the bayberry juice obtained by squeezing fresh fruit at 4°C had the best aroma quality.

The reactions of the N-heterocyclic carbene-phosphinidene adducts (NHC)PSiMe₃ and (NHC)PH with the dinuclear ruthenium and osmium complexes [(η⁶-p-cymene)MCl₂]₂ (M = Ru, Os) afforded the half-sandwich complexes [(η⁶-p-cymene){(NHC)P}MCl] and [(η⁶-p-cymene){(NHC)PH}MCl₂] with two- and three-legged piano-stool geometries, resp. (NHC = IDipp, IMes; IDipp = 1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene; IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene). The complexes were initially tested as precatalysts for the hydroboration of benzonitrile, and the most active species, the ruthenium complex [(η⁶-p-cymene){(IMes)P}RuCl], was further used for the efficient hydroboration of a wide range (ca. 50 substrates) of nitriles, carboxylic esters, and carboxamides in neat pinacolborane (HBpin) under comparatively mild reaction conditions (60-80°C, 3-5 mol % catalyst loading). Preliminary mechanistic and kinetic studies are reported, and stoichiometric reactions with HBpin indicate the initial formation of the monohydride complex [(η⁶-p-cymene){(IMes)P}RuH] as the putative catalytically active species.

Guo, Qiyong published the artcileComparative analysis of volatile profiles in four pine-mushrooms using HS-SPME/GC-MS and E-nose, Synthetic Route of 103-26-4, the publication is Food Control (2022), 108711, database is CAplus.

Pine-mushrooms is rich in bioactive compounds, possess a unique aroma profile for culinary art. In China, pine-mushroom has been produced in Southwest and Northeast area. However, the discrepancy of volatile profiles in pine-mushrooms from two regions was unclear due to different extraction and detection method applied in research. This study attempted to compare the volatile profiles of four pine-mushrooms from Southwest (LS) and Northeast (HEB, SY, MDJ) using Headspace Solid Phase Microextraction coupled with Gas Chromatog. Mass Spectrometry (HS-SPME/GC-MS) and Electronic nose (E-nose). showed a significant difference in aroma profiles among samples. A total of 100 volatile compounds were identified, and separated into 11 classes. Benzaldehyde and hexanal were detected in all samples, which could be the pivotal aroma components in pine-mushrooms. Aromatic components, were present in LS pine-mushroom from Southwest China, including abundant of Me (Z)-N-hydroxybenzenecarboximidate, benzaldehyde, and Me 3-phenylprop-2-enoate. Meanwhile, some alcs. (such as oct-1-en-3-ol, hexan-1-ol) were characteristic compounds present in HEB, SY and MDJ samples. Principal component anal. (PCA) of E-nose data showed a clear distinction among samples. In addition, this study also highlighted the correlation between key volatile compounds detected by GC-MS and E-nose sensors, which could be benefit for further explanation to the origin of differences in sensory quality of pine-mushrooms.

In this study, we investigated the bioactive potential (antibacterial and antioxidant), anticancer activity and detailed phytochemical analysis of Selaginella repanda (S. repanda) ethanolic crude extract for the very first time using different in vitro approaches. Furthermore, computer-aided prediction of pharmacokinetic properties and safety profile of the identified phytoconstituents were also employed in order to provide some useful insights for drug discovery. S. repanda, which is a rich source of potent natural bioactive compounds, showed promising antibacterial activity against the tested pathogenic bacteria (S. aureus, P. aeruginosa, E. coli and S. flexneri). The crude extract displayed favorable antioxidant activity against both 2,2-diphenyl-1-picrylhydrazyl (DPPH) (IC50 = 231.6 mu g/mL) and H2O2 (IC50 = 288.3 mu g/mL) molecules. S. repanda also showed favorable and effective anticancer activity against all three malignant cancer cells in a dose/time dependent manner. Higher activity was found against lung (A549) (IC50 = 341.1 mu g/mL), followed by colon (HCT-116) (IC50 = 378.8 mu g/mL) and breast (MCF-7) (IC50 = 428.3 mu g/mL) cancer cells. High resolution-liquid chromatography-mass spectrometry (HR-LC-MS) data of S. repanda crude extract revealed the presence of diverse bioactive/chemical components, including fatty acids, alcohol, sugar, flavonoids, alkaloids, terpenoids, coumarins and phenolics, which can be the basis and major cause for its bioactive potential. Therefore, achieved results from this study confirmed the efficacy of S. repanda and a prospective source of naturally active biomolecules with antibacterial, antioxidant and anticancer potential. These phytocompounds alone with their favorable pharmacokinetics profile suggests good lead and efficiency of S. repanda with no toxicity risks. Finally, further in vivo experimental investigations can be promoted as probable candidates for various therapeutic functions, drug discovery and development.

The aminohydroxylation of various alkenes using FmocNHCl as a nitrogen source is reported. In general, in the absence of a ligand, the reaction provided racemic Fmoc-protected amino alcohols with excellent regioselectivity but in low to moderate yields. However, in some instances, the yield of an amino alcohol product and the regioselectivity could be altered by the addition of a catalytic amount of triethylamine (TEA). The Sharpless asymmetric variant of this reaction (Sharpless asymmetric aminohydroxylation (SAAH)), using (DHQD)(2)PHAL (DHQD) or (DHQ)(2)PHAL (DHQ) as chiral ligands, proceeded more readily and in higher yield compared to the same reaction in the absence of a chiral ligand. The enantiomeric ratios (er) of all but two examples exceeded 90:10 with many examples giving er values of 95:5 or higher, making FmocNHCl a highly practical reagent for preparing chiral amino alcohols. The SAAH reaction using FmocNHCl was used for the preparation of D-threo-beta-hydroxyasparagine and D-threo-beta-methoxyaspartate, suitably protected for Fmoc solid phase peptide synthesis.

While the popularity of electronic cigarettes (e-cigarettes) has rapidly increased in recent years, the regulation around the composition of such e-cigarettes has lagged. Many components of the e-cigarettes and liquid flavorings (e-liquids) used in these products are not disclosed, and the potential for exposure to toxic compounds via use of these products is significant. Reported herein is an analysis of the components of e-cigarettes as well as of three popular e-liquids via gas chromatography – mass spectrometry. These results show that components of the e-cigarette contain large quantities of aromatic compounds, and that the e-liquids contain smaller quantities of potentially concerning additives. Most notably, 96% of the extract from the filter was composed of benzyl chloride, a potent DNA alkylating agent, a result which should be of significant concern to consumers, regulatory agencies, and e-cigarette manufacturers.
