a non specific stimulant of immunogenesis; also used for erytrocytes hemolysis and automatic leucocyte numbering.
Triterpene saponine, mixture of 4 glycosides from plants of the Acanthophyllum genus.
Acanthophylloside A: minor component, chemical formula unspecified;
Acanthophylloside B: C₈₆H₁₃₆O₄₈ - 40%;
Acanthophylloside C: C₉₂H₁₄₆O₅₃ - 25%;
Acanthophylloside D: C₈₆H₁₃₆O₄₉ - 25%.

• Molecular Weight : Acanthophylloside B: 1936 Da.
  Acanthophylloside C: 2098 Da.
  Acanthophylloside D: 1952 Da.
  
  
• Solubility in : dissolves in water with stable foam, practically not in alcohol and chloroform.
  
  
• Purity min. : 80% (TLC)
  
  
• Biological Activity : non-specific stimulant of immunogenicity. As an erythrocyte hemolytic, it can be used for leucocyte numbering (2% solution in 0.9% NaCl solution). It can also be used for obtaining barb antigens for diagnostic solution (0.54% Allochroside in 10% virus-containing aphtose suspension) and for the production of inactivated antibarb vaccines.
  
  
• Toxicity (LD₅₀) : mice (i.v.): 3.5 - 7.05 mg/kg.
  
  
• Storage recommendations : Store at +4°C, in dark place.
  
  
• CAS Reg. No. : 141489-39-6
