A method for separating and recovering compounds from biomass is provided. In the method, an aqueous extraction fluid (1) in essentially gaseous phase, such as steam, is propagated through a reaction area (10A) containing biomass feedstock. When extraction fluid (1) advances through the biomass feedstock, in predetermined reaction conditions, a target compound (C1, C2) separates from the essentially solid feedstock matter and travels, with the extraction fluid, towards the end of the reaction area, in where the target compound is recovered in the form of an essentially liquid medium (2). The method is beneficial for extracting long-chain hemicelluloses from cellulose-containing feedstocks.
