摘要：

Solubility of Hibiscus cannabinusL. seed (particle size 400 um) oil in supercritical carbon dioxide was determined at pressure of 34.47-48.26 MPa, temperature of 50-80°C and constant flow rate of 5 mL min-1. It was found that the solubility of Hibiscus cannabinus L. in supercritical carbon dioxide increased with the increased of temperature. The extraction yield increased with increased in temperature and pressure. The maximum yield was 8.66% at 48.26 MPa and 80°C for 40 min of extraction. The mass transfer coefficients for Hibiscus cannabinus L. oil was found to be 0.0072 sec-1 at 48.26 MPa and 80°C. © 2010 Asian Network for Scientific Information.
