    • An extraction apparatus comprising a boiler, an extraction chamber for holding material from which a compound is to be extracted, and a condenser for condensing the vaporized solvent, and returning the condensed solvent to the extraction chamber. A fluid connection between the boiler and the extraction chamber allows passage of vaporized solvent from the boiler to the extraction chamber and condensed solvent from the extraction chamber to the boiler. The extraction apparatus is configured such that, when the extraction apparatus is in use, the solvent moves repeatedly through a cycle in which: the solvent vaporizes within the boiler; the vaporized solvent passes from the boiler into the extraction chamber by way of the at least one fluid connection, and bubbles through condensed solvent within the extraction chamber so as to agitate the condensed solvent; the vaporized solvent condenses in the condenser and returns as condensed solvent to the extraction chamber; the condensed solvent interacts with the material in the extraction chamber to extract the compound; and at least a portion of the condensed solvent containing the extracted compound returns to the boiler from the extraction chamber. A corresponding method is also disclosed.
