Abstract: In this study the technical extraction conditions and the physico-chemical properties of the pigment from the fruit of Nitraria. sibirica Pal1 were investigated. The red pigment has the maximum absorption wavelength at 346 nm. The red pigment can be extracted under the following conditions: drying Nitraria sibirica fruit at about 30 ℃, soaking in 75% and pH 3 ethanol solution at 40 ℃ for 2 hours, and the proportion of meterial to liquid 1:10. The pigment is stable to acid, alkali, light, heat, food additive and metal ion.
