Cyanogenic glycosides

Many plants contain cyanogenic glycosides. Toxicity of the cyanogenic glycoside results when the compound is enzymatically cleaved to release hydrogen cyanide (HCN) that is toxic to the pathogen. Sorghum contains the cyanogenic glycoside dhurrin (6.9). This compound is of interest to both pathologists and entomologists as an example of a preformed resistance compound and acts as an insect feeding deterrent and as a fungicidal agent (Starr et al., 1984; Adewusi, 1990).
