We established callus cultures of the monocotyledonous plants Kniphofia foliosa and K. tuckii (Asphodelaceae), which produce the anthraquinone derivatives chrysophanol and its glycosides. The minor product chrysophanol 8-O-β-gentiobioside was fully characterized by spectroscopic analysis and synthesis.
