A Novel Polysaccharide from Chrysanthemum morifolium

ZHENG Yun, LIU Liu, FANG Ji-Nian   


A novel polysaccharide was isolateded from Chrysanthemum morifolium Ramat. flowers by successive hot water extraction, anion-exchange chromatography and gel permeation chromatography. Sugar and methylation analysis, periodate oxidation, partial acid hydrolysis and NMR spectral analysis revealed that polysaccharide is composed of repeating units with the following structure: Araf-(1→5)-Araf-(1→4)-Glcp-(1→4)-Glcp 1 ↓ 6 [→4-Galp-(1→4)-Galp-(1→4)- Galp-(1→4)- Galp-(1→6)- Galp-(1]→n

Key words: Chrysanthemum morifolium , Asteraceae, polysaccharide, galactan
