Abstract
An experimental design has been built in order to study the influence of different parameters on the crystallization ratio and purity of andrographolide extraction using supercritical CO2: pressure (8–24 MPa), temperature (40–70 °C) and extraction duration (45–105 min). Crystallization ratios are between 14.32 and 72.29 wt%, and purities are between 43.11 and 79.78 wt%, indicating that the experimental design covers a large range of results. The results indicate that pressure and extraction duration are the most influencing parameters.
