人参皂甙（Ginsenoside）是人参及各种人参中成药制剂中的主要成分。其甙元为人参二醇和人参三醇。人参皂甙Rg1是人参三醇甙元下的一种皂甙形式。本文采用高效液相分离分析及紫外可见分光光度检测，以人参营养液中的人参皂甙Rg1进行了定量分析，取得了较好结果，回收率97．46％，变异系数1．103％。
Ginsenoside is the main component of ginseng and various ginseng Chinese medicine preparations. The glycosides are panaxadiol and ginseng triol. Ginsenoside Rg1 is a saponin form of ginseng triol aglycone. In this paper, high-performance liquid separation analysis and UV-visible spectrophotometry were used to quantitatively analyze ginsenoside Rg1 in ginseng nutrient solution. Good results were obtained with a recovery rate of 97.46% and a coefficient of variation of 1.103%.
