The invention relates to a process for obtaining raw materials from autumn foliage, which is characterized by the fallen foliage being comminuted, extracted in one or more stages with one or more solvents and after removing the solvents, the extract or extracts and the residue are separate. The process can be performed with different solvents with different dielectric constant. From the individual extracts there are obtained new perfumes or flavoring agents or intermediate products for producing foods or feeds, or for producing selling agents or binders, as well as cosmetics, pharmaceuticals, cosmetics for treatment purposes, canning agents, fertilizers and inks, while the extraction residue can be used as a sulphur-free fuel.
