Abstract: This paper discussed the way to obtain yellow pigment from Cape jasmine:First, put Cape jasmine into alcohol.The mixed liquid was drawn and extracted, Second, the solid and liquid were separated. Third, filtration of micro-membrane andconcentration of vacuum membrane were carried out. Fourth, yellow pigment was obtained through vacuum extraction by ultra-critical CO2. The rate of extraction, purification and colour of the product were very much promoted in comparison with thetraditional technology and skill.

Key words: Cape jasmine, extraction and refinement of pigment, extraction through ultra-critical CO2
