A new xanthone‐O‐glycoside, the 1,7‐dihydroxy‐3‐methoxyxanthone‐8‐O‐β‐D‐glucopyranoside ( 7 ), has been isolated from the leaves of Gentiana verna L. by means of column chromatography on polyamid. Six known xanthones: 1‐hydroxy‐3,7,8‐trimethoxyxanthone‐1‐O‐primerveroside ( 2 ); 1,7,8‐trihydroxy‐3‐methoxyxanthone ( 3 ); 7‐hydroxy‐3,8‐dimethoxyxanthone‐1‐O‐primeveroside ( 4 ); 7,8‐dihydroxy‐3‐methoxyxanthone‐1‐O‐primeveroside ( 5 ); mangiferin 6 and the flavone C‐glycoside isoorientin 8 have also been isolated and identified.
