Abstract:
Bianthraquinone glycosides are formed during the preparation and conservation of fluid extracts of cascara. Analysis of these preparations has shown that up to 20% of total amount of anthracene glycosides can be dimerized. These dimers are devoid of laxative activity. They are absorbed in the intestine and very slowly excreted.
