CYNOPHORE GLYCOSIDES

• Cyanophore/CYANOGENIC Glycosides

  ● upon hydrolysis yields HCN, benzaldehyde and sugars

  ● Medicinal activity of Cyanogenic glycosides is due

  to the presence of HCN

  ● Test:

  ○ guignard test

  ○ Picric acid

  ○ Addition of mercurous nitrate
• A.Wild Cherries

  ● Aka prunus virginiana / wild black cherry tree

  ● From dried bark/stem - Prunus serotina

  ● Prunasin - formed from the partial hydrolysis of amygdalin
• B. Apricot Pits

  ● Prunus armeniaca

  ● Source of laetrile or amygdalin - with anti cancer claims
• C. Cassava

  ● Mannihot esculenta

  ● Mannihotoxin : toxic cyanogen

  ● Contains linamarin a cyanogen which produces

  cyanide.
