高山红景天多糖RSA部分酸水解产物RSA-c的制备和组成分析

Production and Component Analysis of RSA-c--a Product of Rhodiola sachalinensis Polysaccharide RSA Being Partly Acid-hydrolyzed

从高山红景天(Rhodiola sachalinensis A.Bor)根状茎提取分离出水溶性多糖RSA,经三氯乙酸部分水解后得到RSA-e.IR,PC和 GC分析表明:RSA-c是仅由一种单糖

A water - soluble polysaccharide RSA has been isolated from the rhizome of Rhodiolasacchalinensis A. Bor. A product of RSA - c was obtained after RSA was partly acid -hydrolyzed with TCA. IR, PC and GC analysis indicated that RSA - c was composed of onlyGalA and it was an acid homopolysaccharide.
