Investigation of a betainic alkaloid from Punica granatum

Nat Prod Res. 2005 Jul;19(5):541-6. doi: 10.1080/14786410500034949.

Abstract

Spectroscopic investigations reveal that a hydroquinone pyridinium alkaloid isolated from the leaves of pomegranates Punica granatum L. (X-ray) exists as a mixture of a conjugated and a cross-conjugated heterocyclic mesomeric betaine in aqueous and DMSO-d6 solution. Twofold deprotonation yields an anionic tripole.
