Chrysophanol glycosides from callus cultures of monocotyledonous Kniphofia spp. (Asphodelaceae)

Abstract

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. © 2004 Pharmaceutical Society of Japan.
