Abstract:

Bioactive components of polysaccharides were extracted from roots, stems, and leaves of Oresitroph rupifraga Bge using water extraction-ethanol precipitation. Meanwhile, the contents of polysaccharides were determined at 624 nm by anthrone-sulfuric acid method. The contents of polysaccharides in roots, stems and leaves of Oresitrophe rupifraga Bge were 6.28%, 10.47%, and 3.29%, respectively. These results indicated that stems of Oresitrophe rupifraga Bge are the major locations of bioactive polysaccharides.

Key words: Oresitrophe rupifraga Bge, polysaccharide, determination
