从酸浆果实中分离提取出了多糖,并应用分光光度法对酸浆果实中的多糖含量进行了测定。经蒽酮—硫酸显色,于580nm处测定,其多糖的含量为5.22%,RSD=1.35%(n=3)。研究结果表明,此测定方法简便,样品溶液在4h内显色稳定,重现性较好,平均回收率为98.9%+1.40%,RSD=1.42%(n=3)。 The polysaccharides were isolated and separated from the fruits of the pulp, and the content of polysaccharides in the fruits of the berries was determined by spectrophotometry. The anthrone-sulfuric acid color, measured at 580nm, the polysaccharide content of 5.22%, RSD = 1.35% (n = 3). The results showed that the method was simple, the color of the sample solution was stable and reproducible within 4h, and the average recovery was 98.9% + 1.40%, RSD = 1.42% (n = 3).
