The water-soluble glucan was obtained from Pleurotus florida fruit bodies by hot water extraction, ethanol precipitation, DEAE cellulose dialysis and Sephadex G-75 gel filtration.
      
Water and methanol extracts prepared from the stem of C.
      
Berberine present in the water and methanol extract was determined by RP-HPLC.
      
Methanol extracts demonstrated better inhibitory effects on cultured L929 cells followed by purified berberine from cell suspension cultures and water extracts.

Some important factors affecting the photodegradation, such as the concentration of TiO2, the initial concentration of aniline, and the existing water vapor, are also studied.
      
The optimal eluant is 60% (v/v) ethanol-water with pH value of 10.
      
Particulate iodine speciation from the same measurement campaigns show that the non-water-soluble iodine compounds are the main iodine species during the marine particle formation.
