제목 | Negative pressure cavitation extraction of paclitaxel from Taxus chinensis and its kinetic analysis |
초록 | In this study, the recovery efficiency of paclitaxel from Taxus chinensis was remarkably improved through negative pressure cavitation extraction. Most of the paclitaxel could be recovered from the biomass at a negative pressure of -260 mmHg with a one-time extraction in a short operating time (10-20 min). The pseudo-second-order model was suitable for the kinetic analysis, and the diffusion of paclitaxel in the biomass played a dominant role in the overall extraction rate according to the intraparticle diffusion model. As the negative pressure increased (0, -160, -260 mmHg), the extraction rate constant (4.3325-5.9126 mL/mg·min), the effective diffusion coefficient (1.083x10-12-1.377x10-12 m2/s) and the mass transfer coefficient (1.428x10-7-2.371x10-7 m/s) increased.
