title: Two new ellagic acid rhamnosides from Punica granatum heartwood.
abstract: From Punica granatum heartwood two new ellagic acid rhamnosides, 3- O-methylellagic acid 4-O-alpha-L-rhamnopyranoside (1) and 3,4'-O-dimethylellagic acid 4-O-alpha-L-rhamnopyranoside (2) were isolated together with brevifolincarboxylic acid, 3-O-methylellagic acid and 4,4'-O-dimethylellagic acid.
