1H-NMR CHEMICAL SHIFT OF THE FLAVONOL 5-HYDROXY PROTON AS A CHARACTERIZATION OF 6- OR 8-ISOPRENOID SUBSTITUTION

1H Nmr examination of 6- or 8-isoprenoid substituted flavonols has shown that the location of isoprenoid side chain on A ring can be deduced from the chemical shift of the 5-hydroxy proton.The application of this 1H nmr technique to identification of the
