| Abstract: | Vanillin assay was carried out in H 2SO 4 medium to determine the procyanidin content in aqueous solution of grape seed extract. Factors affecting the colormetric reaction including H 2SO 4 concentration, vanillin concentration, the reaction temperature and reaction time, etc, were studied, and proper reaction condition was obtained. Assessment of the method proved its reliability, and the method was used to determine the procyanidin content of several kinds of grape seeds from different origins and by different wine-making methods. |
