Glycosides are compounds that consist of a sugar molecule bonded to a non-carbohydrate entity, such as an aglycone. Common examples of glycosides include cardiac glycosides like digoxin, which are used to treat heart conditions, and salicin, found in willow bark and converted by the body into salicylic acid, a precursor to aspirin.
Examples of lipids are: sterol glycosides, cerebrosides, and plant phytoglycolipids
Borax is used in the Schotten-Baumann reaction to identify anthraquinone glycosides because it reacts with the anthraquinone to form a precipitate. This reaction is specific for anthraquinone glycosides and does not occur with other types of glycosides.
Glycosides can be classified based on their therapeutic effects into categories such as cardiac glycosides (e.g. digoxin for heart conditions), saponins (e.g. for their anti-inflammatory and cholesterol-lowering properties), and anthraquinone glycosides (e.g. for their laxative effects). Each type of glycoside exerts specific therapeutic actions in the body.

Isolation and estimation of cardiac glycosides can be done using techniques such as column chromatography, thin layer chromatography (TLC), and high-performance liquid chromatography (HPLC). These methods involve extracting cardiac glycosides from plant sources using appropriate solvents, isolating them through chromatographic techniques, and quantifying them using suitable standards and detectors. Additionally, spectrophotometric methods can be employed for the estimation of cardiac glycosides based on their characteristic absorbance properties.
Saponins are natural organic compounds which are frequently found in plants; they are a class of glycosides.
Saponin triterpenoid glycosides, or commonly called ginsenocides.
