摘要： An upward flow extraction method, apparatus, and extract are disclosed. The upward flow extraction method can comprise loading extraction material into an extraction cell having a bottom portion and a top portion; introducing a first aliquot of extraction medium through the bottom portion of the extraction cell; expelling gas from the extraction cell through the top portion of the extraction cell; closing the top portion of the extraction cell and increasing the pressure in the extraction cell as extraction medium flows into the bottom portion of the extraction cell; stopping the flow of extraction medium into the extraction cell; steeping the extraction material in the extraction medium under pressure to produce an extract; and introducing a second aliquot of extraction medium through the bottom portion of the extraction cell to push extract through top portion of the extraction cell.
