Abstract
|
|
|
|
The aqueous ethanolic whole plant extract of Rosa arabica was found to contain the new natural dimeric phenolic compound, ellagic acid 3,3´-dimethyl ether 4-O-α-rhamnopyranoside, 9, along with ten known phenolic metabolites (1-8, 10 and 11). Structures of all compounds (1-11) were established by routine methods of analysis and confirmed by FAB-MS, ¹H and ^(13)C NMR spectral analysis.
