AB-8树脂和D101树脂纯化桑叶多糖的比较

Compare of polysaccharide in sangye purified AB-8resin and D101 resin

犤目的犦试验针对有降血糖作用的水溶性桑叶多糖成分的纯化工艺进行比较。犤方法犦桑叶的水煎液分别用两种大孔吸附树脂洗脱分离。用分光光度法分别测定两个采用不同树脂工艺所得水溶性桑叶多糖的含量。犤结果犦采用AB-8树脂提取桑叶多糖产率与采用D101树脂提纯化桑叶多糖产率相比较不仅无显著差异,而且产率也比较稳定。犤结论犦AB-8树脂和D101树脂都可作为纯化桑叶多糖的工艺。

To compare the different purification of water-soluble polysaccharide in sangye with lowering blood sugar effect.The elution separation of the decocted solution of sangye was done by two kinds of absorb resin with bigger foramen.The content of polysaccharide obtained by different methods was detected with spectrophotom-etry.There was no difference of productivity between using AB-8resin and D101resin.The productivity was stable.[Conclusion]AB-8resin and D101resin both can be used to purify polysaccharide in sangye.
