Functional Components

The pigments in black and red peanut skins were comparative analyzed in this paper. The pigments were extracted with ethanol solution, purified by AB-8 macroporous resin, and black peanut skins pigment (BPSP) was separated by ethyl acetate to obtain different compositions. The compositions of pigments were qualitatively analyzed by special chemical reaction of organics and UV-visible spectrophotometry. The results show that the compositions of BPSP are mainly anthocyanins and proanthocyanidins, and the contents are 9.39% and 16.62%, respectively. The proanthocyanidins are found in red peanut skins pigment (RPSP), and the content is 24.51%, and no anthocyanin is checked out. It is convenient, rapid, economical and effective for special chemical reaction of organics and UV-visible spectrophotometry, and it is suitable for preliminary identification of natural organics structure.
