| Abstract: | The extraction method of pigment from Lycium barbarum was studied. Using the petroleum ether as organic solvents in the extraction that the proportion of solid materials arel is 1 ： 23. Extraction temperature is 85 ℃. Extraction time is 3h. The spectrophotometer measurements were conducted at 445 nm of the orange red extraction of Lycium barbarum pigment. The solubility and the stability of pigment are presented in this paper with different temperature, pH, 1 ight, oxidants and metal ions. |
