Abstract: The stability of red pigment extracted from the fruit of Nitraria sibirica Pall.of Xinjiang was studied. The results showed that the stability of the Nitraria fruit pigment was influenced by various degree of temperature, pH, oxidant, reducing agent, illumination, metal ion, additive and so on. There are more obvious influence of pigment stability by oxidant, reducing agent, Fe3+, Al3+,Cu2+

Key words: fruit of Nitraria sibirica Pall, red pigment, stability
