ABSTRACT
The solubility of Ferulic acid and Tetramethylpyrazine in supercritical carbon dioxide was determined at temperatures from 308 to 338 K and pressures from 10 to 35 MPa. The data presented in this work are valuable to know the possibility of their extraction from Ligusticum Chuanxiong Hort.with supercritical carbon dioxide. Experimental data of the solubility of Ferulic acid and Tetramethylpyrazine were correlated by Chrastil equation and the value of AARD was 12.92% and 4.23% respectively.
