Extraction of the Pectin from Virginica Stem Bark and Study on its Structure and Composition

Abstract:

Using virginica stem bark as raw material, extracted with hydrochloric acid, sulfuric acid, and tartaric acid through an orthogonal experiment. Then, the structure of pectin was analyzed and compared with mulberry pectin. The result showed that the pectin extraction rate was stable and relative high when using tartaric acid diluents as extracting solution, with pH value at 2 and extraction time of 90 minutes. There were certain differences about the color of the pectin when extraction process was different. Infrared spectrum analysis showed that the composition of the pectin in virginica stem bark was basically same as that in mulberry branch bark.
