[Objective] The aim was to study the problems in the application of natural dye. [Method] A proposal for extraction of pigment in marigold was offered. The best extraction agent, the most suitable solid-liquid ratio and the mostappropriate extraction time were determined. [Resultl The results showed that ： the extraction rate of pigment was higher in binary mixed solvent than in single solven. The more suitable solvent was the mixed solvent which ratio of petroleum ether and ethanol was 3：2. The pigment should be extracted triple, the most suitable solid-liquid ratio was 1：15, and the most appropriate extraction time was 2.5 h. The material was easy of access, and extraction process was simple and highly efficient. It had low energy consumption and no pollution. [Conclusion] The best result would appear by utilizing the mixed solvent which ratio of petroleum ether and ethanol was 3：2. solid-liquid ratio was 1：15, the pigment should be extracted triple, and each time costed 2.5 h.
