Meaning and Definition
The classification of organisms based on differences and similarities in their biochemical composition, especially chemical compounds like proteins, alkaloids, or flavonoids.
A sub-discipline of systematics that uses chemical data to establish taxonomic relationships, resolve evolutionary lineages, or identify species. It can also refer to the methodology itself for creating chemical profiles of organisms.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The concept and term are identical in both varieties. Spelling follows the standard pattern (e.g., 'classification' not 'classifycation').
Connotations
Purely technical and neutral in both regions. Implies a rigorous, laboratory-based scientific approach.
Frequency
Extremely rare outside of specific academic contexts in both the UK and US. Slightly higher frequency in British ecological and botanical literature historically.

Common Mistakes When Using “chemotaxonomy”
- Misspelling as 'chemotaxinomy' or 'chemotaxomony'.
- Using it as a countable noun (e.g., 'a chemotaxonomy') instead of an uncountable/mass noun.
- Confusing it with 'chemotyping', which is narrower in scope.
FAQ
Frequently Asked Questions
Yes, but often integrated with molecular phylogenetics. It remains crucial for identifying microorganisms (like bacteria and fungi), classifying plants (especially in complex groups like algae, bryophytes, and some angiosperms), and in drug discovery from natural sources.
It depends on the group. For plants: alkaloids, flavonoids, terpenoids, phenolic acids. For bacteria: fatty acids, proteins, pigments. For fungi: secondary metabolites, mycotoxins, polysaccharides.
Chemotaxonomy uses chemical phenotypes (expressed compounds), while DNA barcoding uses genetic sequences (DNA). Chemotaxonomy can reflect ecological adaptations or immediate physiological states, whereas DNA shows evolutionary history.
Extremely unlikely. You might find it in popular science articles about newly discovered species, rare plant identification, or advanced nature documentaries focusing on scientific methodology.
