摘要

The present invention relates to a plant cell extract with adjuvant activity obtainable by extracting fresh plant material consisting of substantially living cells, originating from saponin producing plants of the genera Quillaja, Saponaria or Gypsophilia. Furthermore the invention provides compounds having adjuvant activity obtainable by separating the plant cell extract into its components. Both the extract and the compounds thus obtained have various applications in adjuvants and vaccines.
