Prenylated benzopyran derivatives from two Polyalthia species
1996
Two new benzopyran derivatives, (6E,10E)-isopolycerasoidol and polycerasoidin methyl ester, have been isolated from a methanolic extract of the stem bark of Polyalthia cerasoides. Their structures were established on the basis of chemical and spectral evidence. Polyalthia sclerophylla contains (6E,10E)-isopolycerasoidol, besides the known polycerasoidin and polycerasoidol. In addition, a known phenylpropene derivative, trans-asarone, has also been isolated from both species and fully characterized.
Protein Biomarkers of Bovine Defective Meats at a Glance: Gel-Free Hybrid Quadrupole-Orbitrap Analysis for Rapid Screening
2021
An understanding of biological mechanisms that could be involved in the stress response of animal cattle prior to slaughter is critical to create effective strategies aiming at the production of high-quality meat. The sarcoplasmic proteome of directly extracted samples from normal and high ultimate pH (pHu) meat groups was studied through a straightforward gel-free strategy supported by liquid chromatography hybrid quadrupole-Orbitrap high-resolution mass spectrometry (LC-HRMS) analysis. A stepped proteomic pipeline combining rapid biomarker hunting supported by qualitative protein Mascot scores followed by targeted label-free peptide quantification revealed 26 descriptors that characterize…
