摘要：

Piperine is a member of the lipids family commonly found in peppercorn,ginger and other natural sources and is grouped as an alkaloid.The solubility of piperine has been determined in carbon dioxide at near critical and supercritical conditions in a dynamic extraction apparatus.The conditions studied were at pressures ranging from 10 to 20 MPa and temperatures at 293,300,313,323 and 333 K.The results showed that piperine solubility increased with increasing pressure at all temperatures studied.The solubility of piperine in near critical conditions was slightly higher than that at supercritical conditions only at the low-pressure range.Two semi-empirical density dependent correlations,namely the Chrastil model and the Dilute Solution model,were also used to estimate the solubility data.Although both models showed good correlation with the solubility data,the Dilute Solution model performed better prediction than the Chrastil model.
