A term used in phytomedicine and pharmacognosy to describe a proposed class of plant-derived substances characterised in research literature by their capacity to interact non-specifically with the hypothalamic-pituitary-adrenal (HPA) axis and sympathoadrenal system, without meeting the threshold for a registered therapeutic claim in Australia.

A naturally occurring, nitrogen-containing organic compound produced by plants (and some fungi and animals) that typically exerts pronounced physiological effects in humans and other mammals.

Anthocyanins are a class of water-soluble flavonoid pigments responsible for the red, purple, and blue colouration found in many fruits, flowers, and vegetables.

A bitter principle is a structurally diverse class of intensely bitter-tasting secondary metabolites found in plants, characterised by their ability to stimulate taste receptors rather than by any single shared chemical scaffold.

Carotenoids are a large class of fat-soluble pigments synthesised by plants, algae, and some fungi and bacteria, responsible for yellow, orange, and red colouration in many fruits, vegetables, and flowers.

A concentrated, volatile aromatic extract obtained from plant material — typically by steam distillation, cold expression, or solvent extraction — that captures the characteristic odour compounds of the source species.

Flavonoids are a large class of polyphenolic secondary metabolites found widely across the plant kingdom, characterised by a fifteen-carbon skeleton arranged in two phenyl rings joined by a three-carbon bridge.

A glycoside is a plant-derived organic compound in which one or more sugar molecules are chemically bonded to a non-sugar component (the aglycone), a structural arrangement that influences how the compound is stored in plant tissue and how it behaves once the bond is cleaved.

Mucilage is a class of high-molecular-weight, water-soluble (or water-swelling) polysaccharides produced by many plants, characterised by a viscous, gel-like consistency when hydrated.

Phytosterols are a class of naturally occurring sterol compounds found in plant cell membranes, structurally analogous to cholesterol in animals, and the subject of ongoing phytochemical and nutritional research.

Polyphenols are a structurally diverse class of plant-derived secondary metabolites characterised by multiple phenolic hydroxyl groups, found widely across fruits, vegetables, legumes, and botanical preparations.

A resin is a solid or semi-solid amorphous mixture of organic compounds — primarily terpenoids and phenolic constituents — secreted by specialised plant cells, typically as a protective response to mechanical injury, pathogen attack, or environmental stress.

Saponins are a structurally diverse class of plant-derived glycosides characterised by a lipid-soluble aglycone (sapogenin) core bonded to one or more hydrophilic sugar chains, giving them pronounced amphiphilic and surface-active properties.

Tannins are a structurally diverse class of polyphenolic plant secondary metabolites characterised by their ability to bind and precipitate proteins, forming the chemical basis of leather-tanning and astringency in foods and plant extracts.

A volatile oil (also called an essential oil) is a complex, lipophilic mixture of low-molecular-weight organic compounds produced in specialised plant secretory structures, characterised by rapid evaporation at room temperature and a distinctive, often intense aroma.
