Study on the Pigment of Lycium ruthenicum Murr.

Abstract

Abstract: This paper systematically studies the physical, chemical property and stability of the pigment of Lycium ruthenicum Murr., the results show that it is a type of anchocyanin and easy to solve in water, having resistance against heat in acid conditionand good resistance against visible light and vltravidet light. It is also found in the experiment that surose preservative don’t exert negative effects on the stability of the pigment while H2O2 has negative effects and Na2SO3 doesn′t have obvious effects, metal ions such as Fe2+, Fe3+, Al3+, Pb2+, Sn2+ have negative effects with a certain of the metal ion density.

Key words: , pigment of Lycium ruthenicum Murr.； physical and chemical property； stability；
