Abstract:
Objective To optimize the supercritical CO2 extraction conditions of volatile oil from Wenjing Huoxue cataplasm. Methods On the basis of single factor investigation on the comprehensive score of extraction yield , osthole content and isoimperatorin, the effects of extraction temperature, pressure and time on the comprehensive score of extracted volatile oil were optimized by orthogonal design. Results In the single factor experiment, the factors that had a great influence on the comprehensive score of the extracted volatile oil were extraction temperature, extraction pressure and extraction time. The orthogonal experiment results showed that the extraction temperature and extraction pressure had a significant influence on the comprehensive score of volatile oil. The optimized extraction process was as follows: extraction temperature at 55 ℃, extraction pressure as 30 MPa, and extraction time as 2 h. Conclusion The extraction process optimized in this experiment is stable and feasible, which could be used for the extraction and preparation of the volatile oil.
