Abstract: This paper studied the extraction method, basic properties and stability of the yellow pigment obtained from Jasmine nudiflorum L. The effects of pH value, metal ions, oxidants, temperature and light on the stability of the yellow pigment were studied. The optimum technology of extraction is that the sample: solvent (1:40), selecting acetone (pH=6.0), heated at 60℃ for 1.0h.

Key words: Jasmine nudiflorum L, pigment, extraction, stability
