Metabolic profiling of Polyporus umbellatus (Pers.) Fr

Polyporus umbellatus (Pers.) Fr. (Sin. Dendropolyporus umbellatus (Pers.) Jülich) is an edible and medicinal mushroom in the family Polyporaceae (phylum Basidiomycota). Widely distributed in the Northern hemisphere, it is reported for the first time its presence in central Italy, Lazio. Even though the known history of usage in traditional medicine of Polyporus umbellatus, the entire phytochemical profile of both the aqueous and organic extract has not been yet analysed, also specifically from sample of non-Asian origin. In this perspective, it is important to evaluate the presence of other possible bioactive compounds and investigate the quantities of metabolites with a nutraceutical impact. High resolution NMR spectroscopy with ¹H-NMR,¹H-¹H TOCSY, and ¹H-¹³C HSQC was employed, finding 45 metabolites in both aqueous and organic extract, identifying and quantifying compounds of interest for nutrition and human health.
