Phytochemistry of genus Gentiana XIII. Study of flavocic and xantonic compounds in the leaves of Gentiana campestris L. 2nd communication. By means of column chromatography on polyamide, we have isolated from the leaves of Gentiana campestris L. a new xanthone‐O‐glucoside, the 3,4‐dimethoxy‐5, 8‐dihydroxy‐xanthone‐1‐O‐β‐D‐glucopyranoside ( 2 ) and its aglucone, the 3,4‐dimethoxy‐1,5,8‐trihydroxy‐xanthone ( 1 ). The C‐glucosides mangiferin ( 3 ) and swertisin ( 4 ) have also been isolated and identified.
