Abstract:

This paper will give a description of an effective method that analyze s a mixture from the roots of Ampelopsis sinica with direct-coupled LC-NMR . Stop flow experiments were carried out. The main composition was determined as a re sveratrol tetramer Vitisin B by means of  1H-LCNMR and WETGCOSY.

Key words: Liquid chromatography-nuclear magnetic resonance, NMR spectroscopy,  Ampelopsis sinica
