不同年份园参生理和化学性状研究

Research on the Physiology and Chemistry Characteristics of the Cultivated Ginseng Roots in Different Years

目的:更全面地确定人参适宜采收年限,并了解生理指标与有效成分指标的相关性,深化人参采收理论。方法:用比色法测定总皂苷含量,用HPLC法测定单体皂苷含量。用常规方法测定折干率,淀粉、总糖、还原糖、可溶性糖、粗脂肪和可溶性蛋白含量,以及淀粉酶和蔗糖酶活性。结果:人参总皂苷的含量与折干率、各种糖类物质、蔗糖酶活力有很好的相关性。结论:人参有效成分与糖类物质关系密切,长白县栽培人参可从4年时开始采收。

Objective： To identify the optimal harvest year of ginseng roots, and reveal the correlation between the physiological items and the efficiency components for improving the ginseng harvest theory. Methods：The total ginsenoside content was tested with colorimetric method, three single ginsenoside contents were tested with HPLC method, and the root dry to fresh ratio （DF） , the content of starch, total sugar, inverse sugar, soluble sugar, crud fat the activity of amylase and sucrase were tested with common methods. Results：There are a novel correlation between the ginsenosides content and the DF, the saccharide content and the activity of sucrase . Conch^ion：There is a close correlation between the ginsenoside and the saccharide, and the ginseng root can be harvested when it is cultivated four years old in the Changbai County,Jilin Province, China.
