摘要：

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-1-O-primeverosylxanthone, 1-hydroxy-3-methoxy-5-O-primeverosylxanthone, 5-hydroxy-3-methoxy-1-O-beta-D-glucosylxanthone, 3,5,6,7,8-pentamethoxy-1-O-primeverosylxanthone are new natural products. Their structures were established by spectroscopic (UV, EIMS, D/CIMS, H-1 and C-13 NMR) and chemical methods.
