不同品种和年限人参中糖类含量比较研究

A Comparative Study on Sugar Content in Different Varieties of Ginseng Grown for Different Years

[目的]检测不同品种和年限人参糖类成分的含量,并分析其分布规律。[方法]采用紫外分光光度法对高丽参、西洋参、林下参和园参的总糖、还原糖和可溶性多糖含量分别进行检测。[结果]不同品种人参总糖含量以林下参最低;还原糖含量以林下参最低,高丽参和园参含量最高;可溶性多糖含量以林下参和高丽参最高。不同年限园参的检测发现,7年生园参的总糖含量明显降低,还原糖含量明显升高。[结论]不同品种人参糖类含量存在差异,且差异与生长环境和加工程序有一定关系;不同年限园参中糖类的含量与其生长年限有关。

[Objective] To detect sugar content in different varieties of ginseng grown for different years and analyze the distribution rules of sugar content.[Method] Ultraviolet spectrophotometry was adopted to detect the content of total sugar,reducing sugar and soluble polysaccharide in Korea ginseng,American ginseng,ginseng cultivated under forest and planted ginseng.[Result] Of the four ginseng varieties,the ginseng cultivated under forest had the lowest content of total sugar and reducing sugar,the highest reducing sugar content was found in Korea ginseng and planted ginseng,the ginseng cultivated under forest and Korea ginseng had the highest content of soluble polysaccharide.Of the planted ginseng grown for different years,the total sugar content in planted ginseng reduced significantly,while the content of reducing sugar improved obviously.[Conclusion] The sugar content in ginseng varied from varieties to varieties,and was related to the growth environment and processing procedures;while the sugar content in planted ginseng was influenced by its growth years.
