first investigation on secondary metabolites occurring in intact and damaged fruiting bodies of Russula nobilis growing in Europe, are reported. Intact mushrooms contain fatty acid esters of velutinal, while three new sesquiterpenoids, russulanobilines A–C, along with eight known ones were isolated from extracts of injured fruiting bodies. The structures of the new compounds were elucidated on the
