Phytochemistry of genus Gentiana, XIX: Identification of new C‐glycosylflavones in Gentiana pyrenaica L. Five flavone C‐glucosides [6‐C‐β‐D‐glucopyranosyl‐tricine (1) or isopyrenine; 7‐O‐β‐D‐glucopyranosyl‐6‐C‐β‐D‐glucopyranosyltricine (2) or isopyrenine‐7‐O‐glucoside; isoscoparine‐7‐O‐glucoside (3); 7‐O‐β‐D‐glucopyranosyl‐6‐C‐β‐D‐glucopyranosylacacetine (4) and isovitexine‐7‐O‐glucoside (5) or saponarine] as well as the flavonol glucoside isoquercitrine (9) have been isolated chromatographically, using polyamide and cellulose columns, from the aerial parts of Gentiana pyrenaica L. 1 and 2 are new compounds and the first glycoflavones trisubstituted on cycle B. Compound 4 is also encountered for the first time in nature.
