Phytochemistry of genus Genrinna XXV: Study of the flavonic and xanthonic compounds in leaves ofGentim X marcailhouana RY. New cinnamoyl-C-glucosyl-flavones SummaryNine flavonic compounds:trans-cafeoyl-2"-isoorientin (6), trans-feruloyl-2"-isoorientin (7), trans-p-coumaroyl-2"-isoorientin (8), p-O-~-~-glucosyl-trans-cafeoyl-2"-isoorientin (9) and three xanthones : gentioside (lo), isogentisine (1 l), mangiferin (12), have been identified from leaves of Gentiana X marcailhouana RY. Compounds 8 and 9 were described for the first time. The cyclitol L-(+)-bornesitol(l3) has been also isolated.

Phytochemistry of Genus Gentiana. XXVI. Identification of a New Di‐O‐glucosyl Cinnamoyl‐C‐glucosylflavone in the Leaves of Gentiana X marcailhouana RY. A new di‐O‐glucosyl cinnamoyl‐C‐glucosylflavone has been identified as 4′‐O‐β‐D‐glucosyl‐2″‐O‐[2‐O‐β‐D‐glucosyl‐2,4,5‐trihydroxy‐(E)‐cinnamoyl]isoorientin (1).
