Citrus peel extracts attenuated obesity and modulated gut microbiota in mice with high-fat diet-induced obesity

Polymethoxyflavones (PMFs) and hydroxyl PMFs (HOPMFs) are mainly found in citrus peel and have shown anti-obesity potential in in vitro and in vivo studies. Herein, we have investigated the anti-obesity effects of two citrus peel extracts obtained via supercritical fluid extraction: PMF A, with a lower content of PMFs and HOPMFs, and PMF B, with a higher content of PMFs and HOPMFs. PMF A and PMF B were administered orally for 16 weeks to mice...
