A method of recovering oleagineous compounds from hydrothermally treated biomass, including providing a biomass feedstock as an aqueous biomass suspension and processing the biomass suspension at a reaction temperature and a reaction pressure for a reaction time in a reactor to produce a product mixture is provided. In a separation step, the product mixture is contacted with an extraction fluid comprising at least one extraction agent selected from the group consisting of monoaromatic hydrocarbons, monoaromatic alcohols and monoaromatic ethers to obtain an organic liquid phase that contains at least a part of the oleagineous compounds. Use of at least one corresponding extraction agent in a method of recovering oleagineous compounds from hydrothermally treated biomass is also subject of the invention.
