Investigation of the underlying mechanism of Buyang Huanwu decoction in ischemic stroke by integrating systems pharmacology-proteomics and in vivo experiments.

Buyang Huanwu Decoction (BHD) has been effective in treating ischemic stroke (IS). However, its mechanism of action remains unclear. The study intended to explore the potential mechanism of BHD against IS using systems pharmacology, proteomics, and animal experiments.

[Supercritical CO2 extraction of fatty oils from bee pollen and its GC-MS analysis].

The extraction of fatty oils from bee pollen with supercritical CO2 was studied. The effects of extraction pressure, extraction temperature and the grinding size of the bee pollen on the yields were discussed. The optimal condition of this method was: extraction pressure 30MPa,extraction temperature 55 degrees C, separator I pressure 14MPa, separator I temperature 45 degrees C, separator II pressure 6MPa, separator II temperature 40 degrees C, extraction period 2 hours.
