| Abstract: | This paper deals with studies on the acyl functions and their substitution site in flavonoid glycosides. As an example, the structure of a navonol glycoside with two glucose units, one rhamnose unitand three acetyl groups in the molecule was studied by means of 2D NMR analyses. For the purposeof systematization of research on the acyl fiavonoid glycosides, a summary was made for acyl functionsfound in flavonoid glycosides and their 13C NMR chemical shift. On the other hand, the chemical shifteffects of acyl groups in the flavonoid glycosides was analysed. |
