Studies on the Composition of Polysaccharide from Bupleurum scorzonerifolium / 中草药

Composition of the polysaccharide from Bupleurum scorzonerifolium Willd. was studiedby high resolution capillary gas chromatography after hydrolysis and followed by acetylation and esterifica-tion of the hydrolysate. The results showed that it is composed of arabinose, ribose, D-xylose, D-man-nose, D-glucose and D-galactose, with a molar ratio of 0. 106 : 2. 652 : 4. 070: 0. 519 : 0. 930 : 2. 518.
