Phytochemistry of genus Gentiana XXV: Study of the flavonic and xanthonic compounds in leaves of Gentiana X marcailhouana R Y . New cinnamoyl‐ C ‐glucosyl‐flavones Nine flavonic compounds: isoorientin ( 1 ), isovitexin ( 2 ), isoorientin‐4′‐ O ‐β‐ D ‐glucoside ( 3 ), isovitexin‐4′‐ O ‐β‐ D ‐glucoside ( 4 ), luteolin‐7‐ O ‐β‐ D ‐glucoside ( 5 ), trans ‐cafeoyl‐2′′‐isoorientin ( 6 ), trans ‐feruloyl‐2′′‐isoorientin ( 7 ), trans‐p ‐coumaroyl‐2′′‐isoorientin ( 8 ), p‐O ‐β‐ D ‐glucosyl‐ trans ‐cafeoyl‐2′′‐isoorientin ( 9 ) and three xanthones: gentioside ( 10 ), isogentisine ( 11 ), mangiferin ( 12 ), have been identified from leaves of Gentiana X marcailhouana R Y . Compounds 8 and 9 were described for the first time. The cyclitol L ‐(+)‐bornesitol ( 13 ) has been also isolated.
