Abstract:
The effect of far ultraviolet radiation on scavenging active oxygen radiacal of polysaccharides from Sargassum thvnbergii and Sargassum kvrneri was studied. The results showed that the scavenging superoxide an ion radiacal levels of two polysaccharides were obviously decreased after 24h by UVc radiation,but the inhibition of the peroxidization of PU-FA was very prominent.The changes of IR spectra before and after far ultraviolet radiation on the two polysac-charide were also studied by differential scanning calorimetry(DSC)and infrared absorption spectroscopy(IR)
