Polysaccharides from Fritillaria pallidiflora Bulbs and Their Antioxidant Activity
- 64 Downloads
Aqueous extraction, alcohol precipitation, and ion-exchange chromatography of Fritillaria pallidiflora Schrenk bulbs isolated for the first time neutral water-soluble polysaccharide FPSP-N, the structure of which was characterized by FTIR spectroscopy and gas chromatography (GC). The results showed that the isolated compound was a heteropolysaccharide with the monosaccharides Glc, Gal, Ara, Man, Xyl, and Rha. The polysaccharide FPSP-N possessed strong antioxidant properties with respect to the DPPH radical in in vitro tests.
The plant F. pallidiflora is a member of the lily family and grows in Xinjiang-Uyghur Autonomous Region of China. Bulbs of F. pallidiflora have been used for hundreds of years in traditional Chinese medicine as a cough suppressant, antiasthmatic, and expectorant . Therefore, further studies of its polysaccharide composition on the molecular level could expand its potential for applications in the pharmaceutical industry. Studies of polysaccharides with...
