Overview of the Metabolite Composition and Antioxidant Capacity of Seven Major and Minor Cereal Crops and Their Milling Fractions.

Cereal grains play an important role in human health as a source of macro- and micronutrients, besides phytochemicals. The metabolite diversity was investigated in cereal crops and their milling fractions by untargeted metabolomics ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) of 69 samples: 7 species (barley, oat, pearl millet, rye, sorghum, triticale, and wheat), 23 genotypes, and 4 milling fractions (husk, bran, flour, and wholegrain). Samples were also analyzed by antioxidant activity.

Omics data reveals the phenolic fingerprint of Brazilian whole wheat flours of different technological qualities.

Unlabelled: Common wheat () is one of the most consumed staple foods used for bakery products. Outer layers of grain present a great diversity of bioactive compounds, especially phenolic compounds (PC). Free and bound PC were extracted from eight genotypes of whole wheat flours (WWF) presenting different technological classifications.

Rice Bran Lipidome Identifies Novel Phospholipids, Glycolipids, and Oxylipins with Roles in Lipid Metabolism of Hypercholesterolemic Children.

Scope: The purpose of the study is to characterize the chemical diversity in rice bran (RB) lipidome and determines whether daily RB consumption for 4 weeks may modulate plasma lipid profiles in children.

Methods And Results: Untargeted and targeted lipidomics via ultra-performance liquid chromatography coupled with high-resolution tandem mass spectrometry (UPLC-MS/MS) are applied to identify bioactive RB lipids from a collection of 17 rice varieties. To determine the impact of RB (Calrose-USA variety) supplementation on plasma lipid profile, a secondary analysis of plasma lipidome is conducted on data recorded in a clinical study (NCT01911390, n = 18 moderately hypercholesterolemic children) before and after 4 weeks of dietary intervention with a control or RB supplemented (15 g day ) snack.

Profile of phenolic compounds in jabuticaba ( sp.) a potential functional ingredient.

Phenolic compounds have attracted a lot of attention due to their benefits to human health. Jabuticaba () fruit has been described as an excellent source of these compounds, while Jabuticaba leaf, considered as plant residue, has shown functional effects. The present study aimed to characterize the phenolic profile in two different leaves extracts (hydroalcoholic ethanol and butanol) of by UPLC-ESI-QTOF-MS.

Effects of cooking on the phytochemical profile of breadfruit as revealed by high-resolution UPLC-MS.

Background: This study evaluated the impact of cooking on the profile of bioactive compounds in unripe breadfruit. To this end, the accessibility of bioactive compounds by various solvents was assessed through total phenolic content and antioxidant capacity analyses. The most efficient solvent was applied to extract the metabolites, which were evaluated by ultra-performance liquid chromatography coupled with high-resolution quadrupole time-of-flight mass spectrometry in MS mode.

Metabolomic approach for characterization of phenolic compounds in different wheat genotypes during grain development.

The phenolic-profiling of seven different wheat (Triticum aestivum) genotypes was investigated for the first time during different stages of grain development (milky, softy, physiological maturity and mature). Free and bound phenolic compounds were extracted separately and analyzed by UPLC-QTOF-MS. Total phenolic content significantly decreased, up to 50% depending on the genotype, towards the maturation of grain.

Dataset on phenolic profile of seven wheat genotypes along maturation.

This article contains data on phenolic-profiling of seven wheat genotypes along maturation (softy, milky, physiological maturity and mature). This supplementary data is related to research "Metabolomic approach for characterization of phenolic compounds in different wheat genotypes during grain development" (Santos et al., 2018).
