✦ Synopsis

Phytochemistry of genus Gentiana, XX. Identification of new di‐O‐glucosides of C‐glucosylflavones in Gentiana asclepiadea L.

Two new O‐glucosides of C‐glucoside flavonic compounds [isoorientin‐2″,4′‐di‐O‐β‐D‐glucoside (1) and isovitexin‐2″‐4′‐O‐β‐D‐glucoside (2)] have been isolated from leaves of Gentiana asclepiadea L. This is the first case of di‐O‐glucosides of C‐glucoside flavones occurring in nature.
