    • Abstract

       

      The13C NMR data of flavonol-3-methyl ethers indicated that the methylation of one of the hydroxyl groups in theo-dihydroxy system causes an upfield shift in the unsubstitutedo-carbon as usual but with the other hydroxylatedo-carbon the shift is always downfield. The spectra of the acetates indicated that 5-OCOCH3 and 5-OCOCH3 resonated downfield compared to that of other acetoxyl groups. The13C NMR data of these compounds is being reported for the first time.
