Tannins from the leaves of Punica granatum

1997

Hussein, S.A.M. | Barakat, H.H. | Merfort, I. | Nawwar, M.A.M.

Leaves of Punica granatum contain the new gallotannins, 1,2,4-tri-O-galloyl-beta-glucopyranose and 1,3,4-tri-O-galloyl-beta-glucopyranose together with the hitherto unknown ellagitannins, 1,4-di-O-galloyl-3,6-(R)- hexahydroxydiphenyl-beta-glucopyranose and brevifolin carboxylic acid 10-monopotassium sulphate. Structures were established by conventional methods of analysis and confirmed by 1H, 13C NMR, 2D-chemical shift correlation NMR and ESI-MS (negative mode) spectrometric analysis.
