Abstract
- The purpose of the study is to characterize the chemical diversity in Rice bran (RB) lipidome and determine whether daily RB consumption for 4 weeks may modulate plasma lipid profiles in children.Untargeted and targeted lipidomics via ultra-performance liquid chromatography coupled with high-resolution tandem mass spectrometry (UPLC-MS/MS) were 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 was conducted on data recorded in a clinical study (NCT01911390, n = 18 moderately hypercholesterolemic children) before and after 4 weeks of dietary intervention (15 g/d) with a control or RB supplemented snack. Untargeted lipidomic revealed 118 lipids as the core of lipidome across all 17 varieties among which phospholipids were abundant and oxylipins present. Phytoprostanes and phytofurans were quantified and characterized. Lipidome analysis of the children plasma following RB consumption revealed the presence of novel polar lipids and oxylipins alongside putative modulations in endocannabinoids associated with RB consumption.The investigation of novel polar lipids, oxylipins, phytoprostanes, and phytofurans in RB extracts provides support for new health-promoting properties especially interesting for people at risk for cardiometabolic disease.
