Abstract:
Objective: To study the best condition of extracting effective component in Daphne odora Thurrb fresh flower by CO 2 supercritical fluid extraction(SFE). Methods: Uniform design was taken in these 4 factors: extracting pressure, extracting temperature, releasing pressure and releasing temperature, together with the experiments of 7 levels in each factor. Results: The best conditon in SFE: extracting pressure 35MPa, extracting temperature 40 ?C , releasing pressure over 8MPa and releasing temperature 36 ?C . Conclusion: This method is simple, highly selective and efficient in extracting effective component of Daphne odora thurrb fresh flowers.
