Objective: To optimize the optimum process parameters of 5-hydroxymethylfurfural in accelerated solvent extraction (ASE) coke. Methods: Selecting the accelerated solvent extraction conditions of coke angelica 5-hydroxymethylfurfural: three factors of extraction temperature, static extraction time and static cycle number were used in Box-Benhnken center combination design. The extraction process parameters were optimized by response surface analysis. And compared with reflux extraction and ultrasonic extraction. Results: Through the optimization and experimental verification, the best experimental parameters for the extraction of coke radix sinensis by accelerated solvent extraction were as follows: heating temperature 50°C, static extraction time 12m in and static cycle times 1. Conclusion: Compared with traditional methods, ASE extraction method has the advantages of convenience, time saving and high extraction efficiency.
