[Analysis of constituents from different parts of Callicarpa nudiflora by UPLC-Q-TOF-MS/MS].

The aim of this study was to clarify the main components of the green leaves of Callicarpa nudiflora,and to compare the difference of main components between the green leaves,yellow leaves,branches and seeds. In this study,ultra-high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) coupled with the UNIFI scientific information system was adopted. And the identification of the main chemical components of C.

Preparation of Chitosan and Water-Soluble Chitosan Microspheres via Spray-Drying Method to Lower Blood Lipids in Rats Fed with High-Fat Diets.

This experiment aimed to investigate the effects of the chitosan (CTS) and water-soluble chitosan (WSC) microspheres on plasma lipids in male Sprague-Dawley rats fed with high-fat diets. CTS microspheres and WSC microspheres were prepared by the spray-drying technique. Scanning electron microscopy (SEM) micrographs showed that the microspheres were nearly spherical in shape.

Hypolipidemic effects of chitosan nanoparticles in hyperlipidemia rats induced by high fat diet.

The aim of this study was to investigate the hypolipidemic effects of chitosan nanoparticles(CTS-NP) preparations with ionotropic gelation, rotary evaporation, and spray-drying technique. Male SD (Sprague-Dawley) rats were separated into five groups, a normal diet group, a high fat emulsions group, a CTS control group and CTS-NP groups treated with two different doses of CTS-NP. The nanoparticles were spherical in shape and had a smooth surface.
