Editing Crocus (section)

=== Phytochemistry ===
The Iridaceae contain a wide range of [[phenolic compounds]]. However, [[6-Hydroxyflavone]]s are found only in ''Crocus'', which is also [[characterised]] by the presence of [[crocin]]s, water-soluble yellow [[carotenoid]]s, in the floral tissues. Crocin is a [[diester]] of [[crocetin]], responsible for the colour of the styles and stigma of ''C. sativus'', and hence saffron.{{sfn|NCBI|2022a}}{{sfn|NCBI|2022b}} A few species contain [[mangiferin]], a {{chem name|glucosylxanthone}}.{{sfn|Goldblatt et al|1998|p=311}}{{sfn|Mohtashami et al|2021}}

While the flowers may vary dramatically between species, there is little variation in the leaves,{{sfn|Harris|2022}} but sufficient variability in corm tunics that they may be used as an aid in differentiating [[taxa]].{{sfn|Serviss et al|2016}}
