   From the journal: Tetrahedron   Abstract During our continuous investigation on a Thai traditional medicinal plant, Stephania venosa Spreng, an alkaloid that seemed to be O-methyldehydrobulbocapnine (MDB) or dehydrocrebanine (DC), had been isolated. However, none of the previously reported 1H- and 13C-NMR data for MDB and DC matched our charts. Thus, we herein report the unambiguous determination of the alkaloid structure as DC via a successful INADEQUATE experiment using 10 mg of the unenriched natural specimen as well as an in silico estimation. Furthermore, ...

   From the journal: Physical Chemistry Chemical Physics   Abstract Solid-state 13C NMR spectroscopy has been used in conjunction with selectively 13C-labeled mono- and disaccharides to measure 13C–13C spin-couplings (JCC) in crystalline samples. This experimental approach allows direct correlation of JCC values with specific molecular conformations since, in crystalline samples, molecular conformation is essentially static and can be determined by X-ray crystallography. JCC values measured in the solid-state in known molecular conformations can then be compared to corresponding JCC values calculated in the same conformations using ...

AccuTOF-DART

May 21, 2020 (Peabody, MA) – JEOL USA announces that it has been awarded a major contract by the US Department of Homeland Security Customs and Border Protection for five JEOL AccuTOF-DART Direct Analysis in Real Time, Time-of-Flight Mass Spectrometers. These instruments will enhance the analytical capabilities of five US Customs and Border Protection laboratories across the country. Three additional labs already installed the AccuTOF-DART in recent years, bringing the total usage to eight ...

A joint paper was published with the RIKEN-JEOL Collaboration Center, Institute for Integrated Cell-Material Sciences (WPI-iCeMS), University of Warwick, and JEOL RESONANCE Inc. This article has also been featured on the cover! Highlights: Selective detection of 1H signals of API in a tablet formulation is proposed. 1H signals of excipients are suppressed. 1H signals in the vicinity of nuclei (here 14N) which only appear in API are excited. 1H{14N} magnetization is diffused to 1Hs in API crystals by RFDR recoupling.   Link to the ...

DART_ethanol concentration_in_Beer_via_DART.jpg

The alcohol content of beverages is tightly regulated, and determination of alcohol content in beverages is important for labeling compliance and quality control.  Traditional testing methods for alcohol content are typically based upon measurements of physical properties such as specific gravity (relative density) and refractive index.  Standardized methods for determination of alcohol by volume use a distillation method to determine specific gravity.  Headspace gas chromatography is typically used in forensic laboratories when there is ...
