This process promotes enzymatic degradation of
cyanogenic glycosides. If the soaking or drying time is too short, enzymatic degradation will be inadequate, and
cyanogenic glycosides remain high (5).
The occurrence of the compound taxiphyllin, which is a
cyanogenic glycoside in raw shoots and its side effect on human health claim to introduce something new way of processing using scientific input to exclude the toxic compound without disturbing the nutrient reserve.The biosynthetic precursors of the
cyanogenic glycosides are different L-amino acids, which are hydroxylated, then the N-hydroxylamino acids are converted to aldoximes and these are converted into nitriles and hydroxylated to a-hydroxy nitriles and then glycosylated to
cyanogenic glycosides (29).

But shoots should be properly processed as they contain high level of toxic
cyanogenic glycosides. Using improved shoot processing methods based on scientific approach instead of crude and unhygienic ones will not only reduce toxic cyanogenic compound but also retain the nutritional values.
Under normal physiological conditions, tissues of cyanophoric plants do not contain free cyanide; rather they contain
cyanogenic glycosides, which upon hydrolysis by endogenous glycosidase yield free cyanide which could be toxic to the consumer [8, 9].
Seasonal variation in the production of tannins and
cyanogenic glycosides in the chaparral shrub, Heteromeles arbutifolia.
Concentration of saponins,
cyanogenic glycosides and alkaloids of trees species consumed by cattle in acahuales of low deciduous forest.
Both plants had more steroids and flavonoids except for the two phytochemicals, anthraquinones and
cyanogenic glycosides which were absent.
Quantification of
cyanogenic glycosides in seedlings of three Macadamia (Proteaceae) species.
Whole-bowel irrigation does offer an opportunity to completely cleanse the gastrointestinal tract of poisonous plant matter and should be reserved for patients who have ingested significant amounts of poisonous plant matter that will release toxins slowly over time in the gastrointestinal tract, such as apple or apricot kernels containing
cyanogenic glycosides or oleander seeds containing cardiotoxic glycosides.
The research has shown that the concentration of
cyanogenic glycosides, which break down to release toxic hydrogen cyanide, increased in plants in elevated CO2.
Cyanogenic glycosides included hydrocyanic acid (HCH), found in peach and cherry pits.
