@@@@The aim of this work is to optimize the Soxhlet extraction process for ursolic acid from Cynomorium. The content of ursolic acid was determined by the UV spectrophotometer method. The extraction condition was optimized using one-factor experimental design and orthogonal experimental design respectively. according to the results obtained in this work, the optimum extraction conditions can be given as follows:the ethanol content in extraction solvent was 95%, the ratio of materials to solvent was 1∶18(g/mL), the extraction temperature was 90 ℃, the processing time was 2 hours, and the extraction process should be repeated twice. Under the condition, the optimum extraction rate, with the value of 38.21 mg/g, was obtained.
