- n. Any of a group of organic compounds, occurring abundantly in plants, that yield a sugar and one or more nonsugar substances on hydrolysis.

- n. A molecule in which a sugar group (the glycone) is bound to a non-sugar group (the corresponding aglycone) by a nitrogen or oxygen atom. Glycosides yield a sugar after undergoing hydrolysis.

The plant stores the cyanide in an inactive form, typically as a cyanogenic glycoside, which is a sugar molecule with an attached cyanide group (carbon triple-bonded to nitrogen).
Plants that contain cardiac glycoside can cause changes in the rate or rhythm of your child's heart.
But a tiny, naturally-occurring steviol glycoside constituent (about two to four percent of a whole leaf) of the plant, called rebaudioside A (also known as reb A, rebiana, stevia extract), was passed into Generally Regarded As Safe (GRAS) status by the FDA in 2008.
Don't experiment with it though as the glycoside content causes vomiting even in moderate doses.
And it seems to have a glycoside called P-57, that does affect the brain's sense of appetite.
It contains vitamins B1, B2, B12, C, and E and is a source of glycoside steroids, which in other plants are known to be responsible for their tonic properties generally and sexual energy—enhancing properties especially.
The cardiotonic activity of arjuna may be due to either or both its glycoside content or the free-radical scavenging actions of the plant s tannins and flavones.
Using chemical and enzymatic methods for analysis of creatinine phosphate, ATP, ADP, and AMP, we showed that neither development of "experimental failure" in vitro (a steady loss of contractile force over hours) nor recovery from failure on addition of a cardiac glycoside was due to changes in concentration of these high-energy phosphates.
These substances may be natural constituents of the seeds, such as gossypol and cylopropenoid fatty acids in cottonseed, cyanogenetic glycoside in linseed, ricin in castor beans, sinigrin or sinalbin in mustard seed, saponin in shea nuts, the trypsin inhibitor in soyabeans, or toxic mould metabolites, such as aflatoxin, which may form if the seeds are allowed to spoil by moulds.
In A. robusta, the glycoside was present without the corresponding hydrolytic enzyme.
