Accurate determination of volatile-flavor components in bos grunniens milk by high-throughput dynamic headspace gas chromatographic-mass spectrometry

A dynamic headspace (DHS) with DVB/CAR/PDMS trapping materials was coupled to a gas chromatography-mass spectrometry for the separation and identification of volatile-flavor compounds in bos grunniens (yak) milk. The principal components analysis coupled with response surface methodology optimized the main variables of the device (10 g sample quality, 5 min desorption time, 3.0 g adding sodium chloride, 72 C extraction temperature, 28 min pre-equilibrium time and 86 min extraction time). Total 235 volatile components were identified. The limit of detections and quantifications of volatile components were 0.01?5.35 mg kg?1 and 0.01?9.41 mg kg?1, respectively, with relative standard deviation from 0.2% to 6.4%. The method performed well during volatile-flavor components analysis from the yak milk sample, producing excellent extraction parameters for the volatile components. Eighty-two volatile components identified in yak milk belonged to a broad range of chemical classes (ketones, aldehydes, aromatics, acids, alkanes, and estes), and 73 of them were at trace levels. Meanwhile, using gas chromatography-olfactometry technique, 11 volatile components were identified as contributors to the aroma of yak milk. In conclusions, a sensitive, convenient and reliable method was developed for the accurate determination of volatile-flavor compounds in yak milk utilizing DHS-GC/MS analyses.

Profiling and Application of Photoredox C(sp3)-C(sp2) Cross-Coupling in Medicinal Chemistry

Recent visible-light photoredox catalyzed C(sp3)-C(sp2) cross-coupling provides a novel transformation to potentially enable the synthesis of medicinal chemistry targets. Here, we report a profiling study of photocatalytic C(sp3)-C(sp2) cross-coupling, both decarboxylative coupling and cross-electrophile coupling, with 18 pharmaceutically relevant aryl halides by using either Kessil lamp or our newly developed integrated photoreactor. Integrated photoreactor accelerates reaction rate and improves reaction success rate. Cross-electrophile coupling gives higher success rate with broad substrate scope on alkyl halides than that of the decarboxylative coupling. In addition, a successful application example on a discovery program demonstrates the efficient synthesis of medicinal chemistry targets via photocatalytic C(sp3)-C(sp2) cross-coupling by using our integrated photoreactor.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C7H12O3, you can also check out more blogs about233276-38-5
