Phytochemistry of genus Gentiana. XXII. Identification of new O ‐glucosides of mangiferin in Gentiana asclepiadea L. Two new O ‐glucosides of mangiferin (mangiferin‐7‐ O ‐β‐ D ‐glucoside ( 1 ) and mangiferin‐6‐ O ‐β‐ D ‐glucoside ( 2 )) have been isolated from the leaves of Gentiana asclepiadea L . This is the first full structure elucidation of naturally occurring O ‐glucosides of C ‐glucosylxanthones. The known C ‐glucosylflavone, saponarin ( 5 ) was also identified.
