Glycone and aglycone
glycoside (hydrolysis) --> glycone (sugar group) + aglycone (non-sugar group)
The sugar group is called a "glycone" and the non-sugar group is called an "aglycone" or genin part of the glycoside.
Upon hydrolysis, a sugar and non-sugar component (aglycone) are formed.
Cadenolide glycosides are steroids from sugars.
They are usually potentially heart toxic, but Digitalis species are used medically.
The glycone can consist of a single sugar group (monosaccharide) or several sugar groups (oligosaccharide).
Aglycone, is the non-sugar component formed when a glycoside is hydrolysed, the non-sugar compound remaining after replacement of the glycosyl group from a glycoside by a hydrogen atom.

Phenolic acids
The term “phenolic acids” is used for phenolic compounds having one carboxylic acid group.
Phenolic acids, phenolcarboxylic acids, are aromatic acid compounds with a phenolic ring and a C6-C1 skeleton, and are weak acids.
Phenolic acids occur in many plant species, especially in dried fruits, basidiomycetes mushrooms, soil humus, and human urine.
Phenolic acids are natural antioxidants, a vital human dietary component, a variety of functions in plants, and are in the therapeutic, cosmetics, and food industries.
These dietary antioxidant property through radical scavenging mechanism, shields against pathological conditions arise from oxidative stress.
Oxidative stress is imbalance between reactive oxygen species and the system's ability to detoxify the reactive intermediates or to repair the resulting damage.
Disturbances in the normal redox state of tissues can cause toxic effects through the production of peroxides and free radicals that damage all components of the cell.
Oxidative stress is involved in atherosclerosis, Parkinson's disease, heart failure, myocardial infarction, Alzheimer's disease, and chronic fatigue syndrome.
The two sub-groups of phenolic acids:
1. Hydroxybenzoic acids, occur conjugated with sugars or organic acids and bound with cell wall lignin.
They occur in red fruits, onions and black radish.
The four commonly found hydroxybenzoic acids are p-hydroxybenzoic, protocatechuic, vanillic, and syringic acids.
2. Hydroxycinnamic acids, occur as simple esters with quinic acid or glucose.
The most common hydroxycinnamic acids are ferulic acid, caffeic acid, p-coumaric acid and sinapic acid.
