超微粉碎对油菜花粉多糖溶出率的影响

目的：比较不同浸提时间下油菜花粉超微粉和普通粉多糖溶出率的差异。方法：采用苯酚-硫酸法检测多糖含量，红外光谱法测定多糖结构。结果：油菜花粉超微粉多糖的溶出量和溶出速度都大于油菜花粉普通粉。超微粉碎和普通粉碎所得的油菜花粉多糖其主要官能团没有差异。结论：超微粉碎技术能显著提高油菜花粉多糖的溶出量和溶出速度，在油菜花粉多糖提取过程中的应用是可行的。

Influence of ultramicro-pulverization on polysaccharide dissolubility of pollen of Brassica campestris L.

Objective：To compare the polyssccharide dissolubility of different time in the compound of pollen of Brassica campestris L.Methods：Phenol-sulfuric acid method was employed to determine polysaccharide contents,infrared spectrum was used to analyse polysaccharide structuze.Resnlts：The dissolution amount and dissolution velocity of pollen of Brassica campestris L.in the ultramicro-powder were sinificantly increased compared with those of ordinary powder .IR spectrum proved that the primary groups of polyssccharide had no difference beiween tow kindo of powder,Conclusion：Ultramicro-pulvecization could remarkably increase the polysacharide dissolubility of pollen of Brassica campestris L.
