In organic chemistry, a cyclitol is a cycloalkane containing at least three hydroxyl, each attached to a different ring carbon atom.{{GoldBookRef|title=Cyclitols|file=C01493|doi=10.1351/goldbook.C01493
Even simple cyclitols can be complicated from the perspective of stereochemistry. For example, cyclohexanetriol exists in three isomers (1,2,3-, 1,2,4-, and 1,3,5-). Furthermore, nine stereoisomers are possible for 1,2,3,4,5,6-cyclohexanehexol (inositol), two of them being enantiomers.

- Ciceritol, a pinitol digalactoside
Phosphates
- Phytic acid; (1R,2S,3r,4R,5S,6s)-cyclohexane-1,2,3,4,5,6-hexayl hexakis[dihydrogen(phosphate)]; inositol hexakisphosphate
Other cyclitols
Applications
Aside from their utility to plants, cyclitols are useful as precursors to synthetic materials.
Analysis methods
Théodore Posternak and others described the separation of cyclitols by paper chromatography using three methods of development: Tollens' reagents, the Meillère reagent (based on the Scherer-Gallois reaction), and digestion by Acetobacter suboxydans followed by Tollens' reagent.
