From a dichloromethane extract of the aerial parts and from a methanolic root extract of Chironia krebsii, 11 1-hydroxyxanthones and six xanthone glycosides have been isolated. The glycosides 5-hydroxy-3-methoxy-l-Oprimeverosylxanthone, 1-hydroxy-3-methoxy-5-O-primeverosylxanthone, 5-hydroxy-3-methoxy-l-O-fl-D-glucosylxanthone, 3,5,6,7,8-pentamethoxy-l-O-primeverosylxanthone are new natural products. Their structures were established by spectroscopic (UV, EIMS, D/CIMS, IH and ~3CNMR) and chemical methods.
