Objective To study the optimal conditions for the effective components in the supercritical CO2 fluid extraction (SFE) from the flowers of Reynolds. Methods A uniform design method was used to extract the four factors of pressure, extraction temperature, analytical pressure and analytical temperature. Each factor was tested at 7 levels. Results The best extraction conditions in SFE: extraction pressure 35 MPa, extraction temperature 40 °C, analytical pressure 5-8 MPa, analytical temperature 36 °C. Conclusion This method is a simple, highly selective and highly efficient method for extracting the active ingredients of Rhododendron flowers from Phnom Penh
