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.
