Hibiscus sabdariffa L. calyces extract using different temperatures (T) at 50-70 C, pressure (P) at 8-12 MPa, and modifier ratio at 5-10%. This work used a supercritical carbon dioxide (SCCO2) extraction with ethanol and water as a modifier. The solubility of the extract was then measured before correlating using Chrastil, del Valle & Aguilera (dVA), and Adachi-Lu (AL) models. This study revealed that a low T and increase in P at a constant modifier ratio would boost the anthocyanins content, contradicted with the extraction of total yield value, which is higher when increase T and low P. Meanwhile, analyzed results show that the solubility of Hibiscus sabdariffa calyces' extracts has successfully fitted the Chrastil's model with AARD of 27.72% as compared with dVA (35.42%) and AL models (50.23%).
