Objective: To establish a microemulsion liquid chromatography system with direct sample loading for determining the serum level of emodin in rats.
Methods: The separation was performed on C₁₈ column (Hypersil BDS, 5 µm,150 mm×4.6 mm) with the microemulsion mobile phase consisting of 3.
The purpose of this study is to explore the feasibility and superiority of using rapid expansion of supercritical solution (RESS) technology in the field of traditional Chinese medicine. The extract of magnolia bark (EMB) was obtained by supercritical carbon dioxide (SCF-CO2) extraction technology. Microparticles of EMB were manufactured by RESS technology.
