| Zusammenfassung: | Two new xanthone‐O‐glycoside, the 1,3,5‐trihydroxy‐xanthone‐8‐O‐β‐D‐glucopyranoside (3), the 1,5‐dihydroxy‐3‐methoxyxanthone‐8‐O‐β‐D‐glucopyranoside (4), have been isolated from the leaves of Gentiana campestris L. by means of column chromatography on polyamid. Two known xanthones (1, 2) which are respectively the aglycones of 3 and 4 and a flavone: iso‐orientine (5) have also been isolated and identified. |
