Abstract: Solubility differences were used method to determine andrographolide in supercritical CO2 with chemical association model to correlate the experimental data.The results showed that the solubility of andrographolide in supercritical CO2 increases as pressure increases and decreases as the temperature rises.Such changes of solubilities obey the classical Chrastil model.

Key words: supercritical CO2, andrographolide, solubility
