  • Publication number: 20080166438
    Abstract: The present invention describes the identification and isolation of chromones and novel chromone compositions from plant sources that exhibit up-regulation of adiponectin production by adipocytes and the normalization of virtually hundreds of genes related to glucose and fatty acid metabolic and signaling pathways. The chromone compositions are effective in enhancing adiponectin production by adipocytes and regulating genes involved in fatty acid biosynthesis, mitochondrial ?-oxidation of fatty acids, steroid biosynthesis, gluconeogenesis, fat transport, PPAR?/RXR? liver signaling and xenobiotic metabolism. The chromone compositions can be used to increase insulin sensitivity, improve glucose tolerance, lower triglyceride levels and balance glucose levels in mammals.
