The extraction technology of Schisandra pigment was optimized by response surface method on the basis of single factor experiment with anthocyanin from Schisandra pigment extract as index and ethanol concentration, extraction time, solid-liquid ratio and extraction temperature as factors. The pigment stability was studied with chroma as index.The results showed that: with the ethanol of concentration of 55% as the extracting solution, the solid-liquid ratio 1∶20g/mL, extracted for 80min at 80℃, the amount of pigment extracted from the fruit can reach the maximum of 11.89 mg/L. The pigment stability experiments showed that light stability was good; sucrose and ascorbic acid were of stable and hyperchromic effect; the pigment was oxygenated easily by hydrogen peroxide, and was stable in acidic, neutral and alkalescent conditions; the pigment changed color under alkali conditions; Ca2+, Mg2+, Na+, K+ had little effect on the stability of the pigment, Al3+ had damaging effect on the stability of the pigment, and Fe3+ and Cu2+ had protective effect on the stability of the pigment.
