[Migration of phenolic active ingredients in Danshen Dizhuye during ultrafiltration of hollow fiber membrane].

Study the suitability of organic film for salvianolic acid in the ultrafiltration process of Danshen Dizhuye. UPLC was used to analyze the migration of nine phenolic active ingredients in Danshen Dizhuye during ultrafiltration of PES hollow fiber membrane and PS hollow fiber membrane. The structural composition of multi-components was analyzed by three different batches of Danshen Dizhuye before and after ultrafiltration of the two membranes.

[Study on "multi-dimensional structure and process dynamics quality control system" of Danshen infusion solution based on component structure theory].

As traditional Chinese medicine (TCM) preparation products feature complex compounds and multiple preparation processes, the implementation of quality control in line with the characteristics of TCM preparation products provides a firm guarantee for the clinical efficacy and safety of TCM preparation products. Danshen infusion solution is a preparation commonly used in clinic, but its quality control is restricted to indexes of finished products, which can not guarantee its inherent quality. Our study group has proposed "multi-dimensional structure and process dynamics quality control system" on the basis of "component structure theory", for the purpose of controlling the quality of Danshen infusion solution at multiple levels and in multiple links from the efficacy-related material basis, the safety-related material basis, the characteristics of dosage form to the preparation process.

Monodisperse rutile microspheres with ultrasmall nanorods on surfaces: synthesis, characterization, luminescence, and photocatalysis.

A complex nanostructure of rutile TiO(2) microspheres with ultrasmall nanorods on surfaces was prepared by a simple solvothermal method. This complex nanostructure is different from the hierarchical structure of microspheres composed of nanorods. The obtained complex nanostructure possesses an epitaxy-like interface between the nanorod-shell and the sphere-core, which often provides superior physical and chemical properties.
