چکیده
Enzymatic browning negatively impacts product quality and shelf-life of packaged fresh-cut lettuce. Metabolite profiles lettuce are affected by the process. The purpose this study was to identify metabolomic marker compounds predict browning, which could be applied discern accessions suited for commercial production industrial breeding programs. Romaine with different susceptibilities were evaluated in two independent trials growing seasons. Metabolites analyzed using ultra-high-performance liquid chromatography coupled high-resolution mass spectrometry (UHPLC-HRMS). Principal component analysis (PCA) performed visualize clusters, trends, discriminative ion features. Seven metabolites, including quinic acid, caffeoylquinic 3-hydroxytetradecanedioic, cichorioside B, 8-deacetylmatricarin-8-sulfate, dicaffeoylquinic acid 9S,12S,13S-trihydroxy-10Z-octadecenoic increased storage time (day 0 vs. day 3) Three lactucopicrin-15-oxalate, tri-4-hydroxyphenylacetyl glucoside 15-deoxylactucin-8-sulfate, decreased 3). Two additional phenolic dicaffeoyltartaric caffeoyltartaric acids, identified as potential compounds, whose presence on samples immediately after cutting correlated development (represented ΔHue). metabolites help elucidate biochemical metabolism pathways during enzymatic have serve predicting resistant accessions.

Xuebijing (XBJ) injection is an ethnomedicinal formula that has been widely used in the therapy of sepsis in China. However, the underlying theraputic mechanisms remain uninvestigated. In this research, a metabolomic method based on UHPLC-Q-Orbitrap HRMSwas applied tomake a holistic evaluation of XBJ on septic rats which were induced by the classical cecal ligation and puncture (CLP) operation....

Apocynaceae is a botanical family distributed mainly in tropical and subtropical regions of the world. In Brazil, they comprise about 90 genera and 850 species, inhabiting various types of vegetation. Within this large botanical family, the genus Hancornia is considered monotypic, with its only species Hancornia speciosa Gomes. Antihypertensive, antidiabetic, and antiviral activities are descri...

Here we present a workflow to analyze the metabolic profiles for biological samples of interest including; cells, serum, or tissue. The sample is first separated into polar and non-polar fractions by a liquid-liquid phase extraction, and partially purified to facilitate downstream analysis. Both aqueous (polar metabolites) and organic (non-polar metabolites) phases of the initial extraction are...
