Abstract
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.
