Abstract

Abstract: Polysaccharides from fruit of quince was obtained by hotwater extraction and ethanol precipitation. The content of polysaccharide was determined by spectrophotometry.The content of polysaccharide assayed by phenol-vitriolic colorimetry at 490nm,was 67.28% with3.08% of RSD (n=4). Recovery value for the polysaccharides assayed was 101.2%. The concentrated polysaccharides was purified by polyamide column and the results showed that decolorization was significant.

Key words: quince polysaccharide, phenol-vitriolic, determination, purification
