Polyphenolic characterisation of plant mixture (Lisosan® Reduction) and its hypocholesterolaemic effect in high fat diet-fed mice

Lisosan® Reduction is a plant mixture produced from powder of fermented Triticum aestivum (Lisosan® G), Desmodium adscendens, Malus domestica, Picrorhiza kurroa and Hordeum vulgare. The aim of this study was to characterise the phenolic profile of Lisosan® Reduction and to evaluate the effects of aqueous extract on mice fed a high fat diet (HFD). Syringic acid, trans sinapic acid and neochlorogenic acid were identified by HPLC-DAD to be the dominant polyphenols of Lisosan® Reduction, followed by vitexin, trans p-coumeric acid and trans ferulic acid. Mice treated with aqueous extract of Lisosan® Reduction (60 mg/kg b.w.) showed a significant decrease of serum cholesterol, glucose and triglycerides level and a significant increase of CYP7A1 gene expression, compared to HFD group.
