| Abstract: | A flavonoid disaccharide compound, quercetin 3 (6 p hydroxy cinnamoyl glucosyl) rhamnosyl, extracted from gingko, is studied by NMR.\ 1H,\ \{13\}C chemical shifts are assigned for the disaccharide. It is shown by \{\}\ \{13\}C chemical shifts and \{\}\ 1H NOE correlation that the rhamnosyl takes a 1 2 connection in this molecule. |
