Study Notes
Anthraquinones
- Anthraquinones are glycosides with a core structure of the anthracene nucleus
- They have two keto groups attached to the benzene ring
- Common sugar moieties include arabinose, rhamnose and others
### Medicinal Uses
- Anthraquinone glycosides are used as stimulant cathartics
- Anthraquinone glycosides cause a more drastic reaction than anthranol and anthrone glycosides
Anthraquinone Action
- Anthranols and anthrones elicit a discomforting “gripping” action
- C-glycosides are activated only after oxidative cleavage in the presence of FeCl3 in acidic mediums
- Anthraquinone dimmers release free anthraquinone (or rhein) and sugar moiety
Anthraquinone Containing Drugs
- Cascara bark, frangula and senna leaves are common anthraquinone glycosides
