  <name>Eupatorin</name>
  <description>Eupatorin, also known as 3',5-dihydroxy-4',6,7-trimethoxyflavone, is a member of the class of compounds known as 7-o-methylated flavonoids. 7-o-methylated flavonoids are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, eupatorin is considered to be a flavonoid lipid molecule. Eupatorin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Eupatorin can be found in lemon verbena, mandarin orange (clementine, tangerine), and peppermint, which makes eupatorin a potential biomarker for the consumption of these food products. </description>

      <definition>A substance that augments, stimulates, activates, potentiates, or modulates the immune response at either the cellular or humoral level. A classical agent (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contains bacterial antigens. It could also be endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Its mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy is related to its antigen-specific immunoadjuvanticity.</definition>
