Porphyran, the sulfated polysaccharide from red algae Porphyra haitanensis, possesses excellent bioactivities, especially the immune activity. In order to provide a water-soluble macromolecule prodrug of 5-FU showing slow release of 5-FU, reducing side-effect, we employed porphyran as a drug car...detailed
In the present study various extraction methodologies have been adopted to derive sulfated polysaccharides (SPs) called as porphyran (POR) from low tide (LT) and high tide (HT) samples of Porphyra vietnamensis. Initially various taxonomical differences among LT and HT samples of P. vietnamensis ...detailed
Porphyran extracted from red algae Porphyra haitanensis is a sulfated polysaccharide, which possesses excellent antioxidant activities. In this study, we prepared the acetylated, phosphorylated and benzoylated derivatives of porphyran. And then the antioxidant activities of all the samples were ...detailed
We found that discolored waste nori with no commercial value, contains much higher level of porphyran than normal nori that is a sheeted food stuff prepared from P. yezoensis used in sushi. Chemical analyses revealed that mean molecular mass of the porphyran prepared from discolored nori (dc-por...detailed
Porphyran, a sulfated polysaccharide, isolated from discolored nori (Porphyra yezoensis) (dc-porphyran) and one fraction (F1) purified from dc-porphyran by DEAE-chromatography showed the protective effects on LPS-induced endotoxin shock in mice. Intraperitoneal (i.p.) treatment with dc-porphyran...detailed
The hypolipidemic and antioxidant effects of porphyran from the red algae Porphyra haitanensis as a dietary supplement were evaluated in mice. The levels of serum TC, TG and LDL-C in MP group increased significantly (pdetailed
