The invention discloses a method for extracting and separating zelanone compounds from Eurasian purpurea. The steps are as follows: air-drying and pulverizing medicinal materials, supercritical CO 2 extraction, molecular distillation separation, industrial chromatographic purification, and finally obtaining 9-carbonyl-10 ,11-dehydrozelenone and 9-carbonyl-10Hβ-zelenone, the obtained products have high purity and high transfer rate, the whole process is reasonable and feasible, the process is simple, the solvent is single and easy to recover, and it is suitable for large-scale industrial production, Has a strong practical value. |
