Abstract

HRGC and HRGC-MS identifications of glycosidically bound Riesling leaf constituents were achieved after extraction with MeOH, Amberlite XAD-2 adsorption, and subsequent enzymatic hydrolysis of the glycoconjugates. Among the enzymatically liberated aglycons 23 bound C13 norisoprenoids were identified. With the aid of multilayer coil countercurrent chromatography (MLCCC) five major C13 glycosides were purified, and their structures ...
