Mariposa Christia vespertillonis (L.) (MCV) Bakh. f. is a plant which commonly known as Mariposa or ‘butterfly wing’ because of the shape of its leaves is similar to a butterfly in terms of its color and shape. This plant has been known to use as a treatment for many diseases such as tuberculosis, bronchitis, inflamed tonsils, colds, muscle weakness and poor blood circulation. Supercritical Fluid Extraction (SFE) is the technology equipment that can be used for the extraction of MCV leaves. SFE is the process of separating one component from another by using supercritical fluids as the extracting media. The aim of this study is to obtain the most optimum conditions in term of temperature, pressure and particle size in order to achieve the high amount of yield in the MCV plant extract. To obtain the design parameter for each samples, three factor of manipulated parameter was used to evaluate the percentage of yield obtain from the extraction of MCV. The manipulated parameters for this experiment are Temperature (T), Pressure (P) and Particle Size (S). In this study, the ranges of each parameter used are based on previous studies.
