NMR spectral analysis of polyphenols from Punica granatum.

Brevifolin carboxylic acid, brevifolin, corilagin, 3,6-(R)-hexahydroxydiphenoyl-alpha/beta)-1C4-glucopyranose, 1,2,6-tri-O-galloyl-beta-4C1-glucopyranose, 1,4,6-tri-O-galloyl-beta-4C1-glucopyranose, ellagic acid, 3,4,8,9,10-pentahydroxydibenzo[b,d]pyran-6-one, granatin-B and punicafolin were isolated from the leaves of Punica granatum. 1H and 13C NMR spectra of brevifolin carboxylic acid and brevifolin have been recorded and assigned for the first time. A new interpretation of the NMR data or related compounds is discussed. The structure of the new natural polyphenol-1,2,3- tri-O-galloyl-beta-4C1-glucopyranose has been established.
