1 The attached cyanide ion inhibits the enzyme, thus causing cell death. The shrub cherry laurel is common in most parts of the UK and Europe. Its leaves contain cyanogenic glycosides, molecules comprising a sugar residue attached to a cyanide-containing non-carbohydrate residue.When these compounds are broken down by enzymes they release HCN.atural cyanide compounds are also found in apricot stones, cherry pips, peach and plum stones, corn, chickpeas, cashews and almonds. The Romans and Egyptians knew this all too well and extracted the prussic acid (hydrogen cyanide) from peach stones to use as a poison. Cherry laurel leaves contain deadly cyanide.
