✦ Synopsis

Phytochemistry of genus Gentiana XXI: The cinnamoyl‐C‐glucosylflavones and their O‐glucosides in Gentiana punctata L.

Three new (1–3) and three previously identified (4–6) cinnamoyl‐C‐glucosyl‐flavones have been isolated from the leaves of Gentiana punctata L. The structures of the new compounds were established as: trans‐cafeoyl‐2″‐iso‐orientin‐4′‐O‐β‐D‐glucoside (1), trans‐feruloyl‐2″‐isovitexin‐4′‐O‐β‐D‐glucoside (2) and trans‐feruloyl‐2″‐isovitexin (3). Isoscoparine (8) and O‐β‐D‐glucosyl‐2″‐iso‐orientin (7) were also isolated and identified.
