Optimization for Degradative Process of Polymeric Proanthocyanidins from Chaenomeles cathayensis
摘要
Abstract
Using the content of (-)-epicatechin-(4β-8)-(-)-epigallocatechin 3-O-gallate (1),the main degradative product of polymeric proanthocyanidins (PPC) fiom Chaenomeles cathayensis with tea polyphenols (TP) as an indicator,the effects of reaction temperature,reaction time,PPC/TP ratio and HC1 concentration on the content of 1 were investigated by single factor experiment,and the degradative process was opyimized by response surface methodology.The results showed that the optimum degradation condition of PPC were established as 70 ℃ of reaction temperature,81.5 min of reaction time,1.5 ∶ 1 of PPC/TP ratio and 1％ of HCl concentration.Under this optimal condition,the actual content of 1 was 601.093 g/mL that was close to the theoretic value (606.103 g/mL),indicated that the response surface method to optimize the degradative process of PPC from C.cathayensis was feasible.关键词
