Estimating the term…
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.

A method for extracting at least one ingredient from a biological sample, wherein a liquid charger of an extraction device is brought in contact with a first side of the sample and wherein an extraction liquid is applied to the first side of the sample by using the liquid charger, wherein further at least one sampling device of the extraction device is used, wherein the sampling device is brought in contact with a second side of the sample and wherein a sample fluid comprising the extraction liquid and the ingredient is collected by using the sampling device, wherein the liquid charger and the sampling device are connected by at least one connection mechanism, wherein the connection mechanism is adapted to vary a distance between the liquid charger and the sampling device and wherein the liquid charger applies a clamping force to the sample located between the liquid charger and the sampling device, wherein the biological sample is taken from a plant and is selected from the group consisting of leaves, trunks, stems, roots, storage roots, branches, inflorescences, flowers, infructescences, fruits, ears, cobs and seeds, wherein the extraction device is clamped onto the biological sample and the extraction is performed without cutting the plant into pieces.
An extraction system, comprising at least one extraction device for extracting at least one ingredient from a biological sample, the extraction device having at least one liquid charger, wherein the liquid charger is adapted to be brought in contact with a first side of the sample and wherein the liquid charger is adapted to apply an extraction liquid to the first side of the sample, the extraction device further having at least one sampling device, wherein the sampling device is adapted to be brought in contact with a second side of the sample and wherein the sampling device is adapted to collect sample fluid comprising the extraction liquid and the ingredient, the extraction system further comprising at least one biological sample, wherein the biological sample is clamped between the liquid charger and the sampling device, wherein the liquid charger and the sampling device are connected by at least one connection mechanism, wherein the connection mechanism is adapted to vary a distance between the liquid charger and the sampling device and wherein the liquid charger applies a clamping force to the sample located between the liquid charger and the sampling device, wherein the biological sample is taken from a plant and is selected from the group consisting of leaves, trunks, stems, roots, storage roots, branches, inflorescences, flowers, infructescences, fruits, ears, cobs and seeds, wherein the extraction device is clamped onto the biological sample for performing the extraction without cutting the plant into pieces.
