不同清蒸工艺对何首乌糖类成分含量的影响

Different steamed process on the influence of multiflower knotweed carbohydrate component content

目的:观察何首乌不同蒸制时间糖类成分的含量变化。方法:用硫酸-苯酚法测定何首乌及其炮制品中还原性糖、水溶性糖和多糖的含量。结果:何首乌炮制后均较生品含糖量高,其中蒸制35 h,100℃干燥,还原性糖和水溶性糖含量最高。结论:清蒸何首乌最佳条件为蒸制35 h,100℃干燥。

Objective：To research the contents of saccharides in radix polygoni multiflori with different steamed time.Methods：contents of reducing saccharides,water-soluble saccharides and polysaccharides in radix polygoni multiflori and its processed products were determined by phenol-sulpheric acid method.Results：The contents of saccharides were the highest of than those in the crude drug,after steaming 35 h,100 ℃ dry,the reducing saccharides and water-soluble saccharides contents were highest.Conclusion：The radix polygoni multiflori optimum condition is to steam for 0.5 h and the desiccation temperature is 100 ℃.
