A new xanthone, a new xanthone glycoside and a known xanthone have been isolated from the chloroform and ethyl acetate fractions of Halenia corniculata (Gentianaceae). They were identified as 1,3-dihydroxy-2,4,5,7-tetramethoxyxanthone, 1-hydroxy-2,7-dimethoxy-3-O-β-D-glucopyranosylxanthone and 1,2,3-trihydroxy-5-methoxyxanthone. 1,3-Dihydroxy-2,4,5,7-tetramethoxyxanthone is a revised structure from 1,6-dihydroxy-2,3,4,8-tetramethoxyxanthone reported by our previous paper.
