目的：人参系龟龄集的君药，为确保本品的质量，建立了人参的含量测定方法。方法：采用薄层扫描法测定龟龄集中人参的人参皂苷Ｒｇ１含量。以氯仿—甲醇—水（６５∶３５∶１０）１０℃以下放置的下层溶液为展开剂；１０％硫酸乙醇溶液为显色剂；双波长反射法锯齿扫描：λｓ＝５４１ｎｍ，λＲ＝７００ｎｍ；狭缝０４ｍｍ×０４ｍｍ；灵敏度：中；线性化参数：ＳＸ＝３。结果：通过方法学考察，点样量在１０３～６１８μｇ范围内呈良好的线性关系，其回归方程为：Ｙ＝３３４２＋７７３３Ｘ，ｒ＝０９９６；平均回收率为１０１２％（ｎ＝３）。结论：试验表明，方法可靠，数据准确，操作简便、易行。 Objective: Ginseng Department of turtle age set of medicine, in order to ensure the quality of this product, the establishment of a method for the determination of ginseng. Methods: The content of ginsenoside Rg1 in Guiling ginseng was determined by TLCS. The lower solution with chloroform-methanol-water (65:35:10) below 10 ° C was used as developing solvent; the solution with 10% sulfuric acid was developed as color reagent; dual-wavelength reflection zigzag scanning: λs = 541nm, λR = 700nm; 0  4mm × 0  4mm; Sensitivity: Medium; Linearization parameter: SX = 3. Results: Through the methodological study, the sample volume showed a good linear relationship in the range of 103 ~ 618μg, the regression equation was: Y = 3342 + 7733X, r = 0996; the average recovery rate was 101  2% (n = 3). Conclusion: The experiment shows that the method is reliable, the data is accurate, the operation is simple and easy.
