This paper reports the separation and determination of monosaccharide composition in lacquer polysaccharide (LPS) by HPLC. The five monosaccharides were analyzed on microBondapak NH2 column (300 mm x 7.8 mm i.d. 10 microns) and refractive index detection. The mobile phase was CH3CN-H2O-CH3OH
Lacquer polysaccharide (LP) from the sap of the lac tree (Rhus vernicifera) was degraded by hydrochloric acid. The molecular weights (M(w)) of hydrolysis products of lacquer polysaccharide (LPD) decreased with the increase of the reaction temperature. Sulfated derivatives (LPDSs) of LPDs were
