An extraction device (110) for extracting at least one ingredient from a biological sample (112) is disclosed, specifically for extracting metabolites from a plant specimen. The extraction device (110) has at least one liquid charger (116) which is adapted to be brought in contact with a first side (122) of the sample (112). The liquid charger (116) is adapted to apply an extraction liquid (128), specifically at least one solvent, to the first side (122) of the sample (112). The extraction device (110) further has at least one sampling device (118) which is adapted to be brought in contact with a second side (124) of the sample (112). The sampling device (118) is adapted to collect sample fluid (126) comprising the extraction liquid (128) and the ingredient.
