Abstract: OBJECTIVE Detection of the sugar content of ginseng from different areas in Changbai Mountains. Analysis of distribution about sugar content in different regions of ginseng. METHODS The total sugar, reducing sugar and soluble polysaccharide in ginsengs from 15 different areas in Changbai Mountains were detected by ultraviolet spectrophotometry. RESULTS Total sugar and reducing sugar levels were the highest in the Changbaixinfangzi and Changbaierdaogang districts, while they were the lowest in Yanjihunchun and Dunhuaqiuligou districts. The level of soluble polysaccharide was the highest in the Dunhuaqiuligou district, and it was the lowest in Changbaixinfangzi and Changbaierdaogang districts. There were other differences of the contents in the rest regions. CONCLUSION There are differences in different regions of ginseng about the total sugar, reducing sugar and soluble polysaccharide. There is a certain relationship between these differences and geography locations.
