 Prunasin, a cyanogenetic glycoside. The pharmacologists main interest in Wild Cherry Bark is due to the presence of the cyanogenetic glycoside prunasin.

 Benzaldehyde;Miscellaneous; 3, 4, 5-trimethoxybenzoic acid (= eudesmic acid), p-coumaric acid, scopoletin (a coumarin derivative), tannins, sugars.

 Main constituents:Wild cherry bark contains cyanogenic glycosides, particularly prunasin. These glycosides, once broken apart in the body, act to relieve choughs by quelling spasms in the smooth muscles lining bronchioles. Although wild cherry is a commonly used ingredient in cough syrups, there are no published clinical trials in humans to support its use for this indication.

 The bark contains prunasin and the enzyme prunase.Samples on hydrolysis yield glucose,benzaldehyde and about 0.07~0.16% of hydrocyanic acid,Also present are benzoic acid,trimethylgallic acid,p-coumaric acid,some tannin and a resin which gives scopoletin on hydrolysis.Modern methods of analysis have allowed detection,for the first time,of amygdalin in the leaves of several Prunus spp.including P.serotina and a cultivar of P.virginiana(F.S.Santamour,Phytochemistry,1998,47,1537).

 Much of the healing activity of wild cherry bark is associated with scopoletin: analgesic, antiarrhythmic, antibacterial, anticonstrictive (in the bronchial tubes), antihepatotoxic, anti-inflammatory, fungicide, lowering blood pressure, lowering blood sugars, relaxing the muscles, "sedating" the uterus. The bark is also about 1/2% hydrogen cyanide, just enough to stop coughing and to relax the bronchial tubes without having any other physiological effects.

 One of the constituents of the berry barks is the cyanogenic glucoside, amygdalin. With the addition of water, it chemically breaks down to form prunasin and then hydrocyanic acid, which is highly toxic and can be lethal even to livestock and humans that eat the leaves of the chokecherry or wild black berry bushes.

 Hydrogen cyanide is a chemical compound with chemical formula HCN. A solution of hydrogen cyanide in water is called hydrocyanic acid. Hydrogen cyanide is a colorless, very poisonous, and highly volatile liquid that boils slightly above room temperature at 26 Deg C. HCN has a faint, bitter, almond-like odor that some people are unable to detect due to a genetic trait.[1] Hydrogen cyanide is weakly acidic and partly ionizes in solution to give the cyanide anion, CN-. The salts of hydrogen cyanide are known as cyanides. HCN is a highly valuable precursor to many chemical compounds ranging from polymers to pharmaceuticals.

 Fruits that have a pit, such as cherries and apricots, bitter almonds and apples, from which almond oil and flavoring are made, contain small amounts of cyanohydrins such as mandelonitrile (CAS#532-28-5). Such molecules slowly release hydrogen cyanide.Some millipedes release hydrogen cyanide as a defense mechanism[4], as do certain insects such as some burnet moths. Hydrogen cyanide is contained in the exhaust of vehicles, in tobacco and wood smoke, and in smoke from burning nitrogen-containing plastics. Cyanide may be a cause of morbidity and mortality in fires.

 100g of crushed apple seeds can yield 217mg of Amygdalin which can generate ~10mg of HCN.
