Abstract: The optimum extraction conditions of pigment in peel of Rose multiflora Thunb. were studied by orthogonal test. And the stability of the pigment was analyzed. Results showed that the highest yield was obtained under the conditions of 60℃, 60% ethanol, 1:6 the ratio, pH6 and extraction time 4 hours. The pigment was resistant to light, heat, acid and common food additives. So as a kind of natural plant pigment it can be used extensively in food, beverage and medicine etc.

Key words: Rosa multiflora Thunb., pigment, extraction, stability, orthogonal test
