Carbon-13 Nuclear Magnetic Resonance Spectra of Phenolic Glycosides Isolated from Chestnut Galls

Abstract
The 13C-NMR spectra of 5 phenolic glycosides, dimethyl crenatin, cretanin, neocretanin, chesnatin (8) and chestanin (9) isolated from galls were compared and the structures 8 and 9 were confirmed as proposed in previous papers.
