人参、西洋参和红参中糖类含量的比较研究

Comparative Study of Sugar Content in Panax ginseng,P.quinquefolium and Red Ginseng

目的:测定不同产地、不同年限的人参、西洋参和红参中糖类成分的含量,并分析其含量分布规律。方法:以葡萄糖作为对照品,采用紫外分光光度法对不同产地、不同年限的人参、西洋参、红参中的总糖、还原糖和可溶性多糖的含量进行测定。结果:不同产地、不同年限的人参、西洋参和红参总糖的含量差别不大;还原糖含量以西洋参最低,人参和红参差别不明显;可溶性多糖含量红参最高,人参次之。结论:人参、西洋参和红参中糖类含量存在差异,这种差异与产地和生长年限有关,亦导致它们的药效有差异。

OBJECTIVE： To determine the contents of sugar in Panax ginseng, P quinquefolius and red ginseng of different ag- es from different producing area, and to analyze the distribution regularity of it. METHODS ： Using glucose as control, UV spectro- photometry was used to test the contents of total sugar, reducing sugar and soluble polysaccharide in P ginseng, P quinquefolium and red ginseng of different ages from different producing area. RESULTS ： There was little difference of the total sugar content in P ginseng, P quinquefolium and red ginseng of different ages from different producing area; the content of reducing sugar was the lowest in P. quinquefolium, but there was no significant difference in P ginseng and red ginseng. The content of soluble polysaccha- ride was the highest in red ginseng, followed by in P ginseng. CONCLUSION： There were differences of the sugar content in P ginseng, P. quinquefolium and red ginseng. The differences relate to producing areas and producing years. This leads to the differ- ence of efficacy.
