Component analysis of cultivated ginseng, cultivated wild ginseng, and wild ginseng and the change of ginsenoside components in the process of red ginseng.

摘要

Objectives The aim of this experiment is to provide an objective differentiation of cultivated ginseng, cultivated wild ginseng, and wild ginseng through component analysis, and to know the change of ginsenoside components in the process for making red ginseng. Methods Comparative analysis of ginsenoside Rb1, Rb2, Rc, Rd, Re, Rf, Rg₁, Rg₃, Rh₁ and Rh₂ from the cultivated ginseng 4 and 6 years, cultivated wild ginseng, and wild ginseng were conducted using High Performance Liquid Chromatography(hereafter HPLC). And the same analyses were conducted in the process of red ginseng. Results 1. For content comparison of ginsenoside Rb₁, Rc, Rd, Rf, Rg₁ and Rh₁, wild ginseng showed high content, followed cultivated ginseng 4 and 6 years, cultivated wild ginseng showed low content than any other samples. 2. For content comparison of ginsenoside Rb₂ and Re, cultivated ginseng 4 years showed high content, followed wild ginseng and cultivated ginseng 6 years, cultivated wild ginseng showed low content than any other samples. 3. For content comparison of ginsenoside Rg₃, wild ginseng and cultivated wild ginseng were only showed low content. 4. For content comparison of ginsenoside Rh2, cultivated wild ginseng was only showed low content. 5. In the process of red ginseng, ginsenoside Rb₁, Rb₂, Rc, Rd, Rg₃ and Rh₁ were increased, and ginsenoside Re and Rg₁ were decreased in cultivated wild ginseng. 6. In the process of red ginseng, ginsenoside Rg₃ and Rh₁ were increased, and ginsenoside Rb₂, Rc, and Re were decreased in cultivated ginseng 4 years. 7. In the process of red ginseng, ginsenoside Rb₁, Rb₂, Rf and Rh₁ were increased, and ginsenoside Rc and Rd were decreased in cultivated ginseng 6 years. Conclusions Distribution of ginsenoside contents to the cultivated ginseng, cultivated wild ginseng, and wild ginseng was similar and was not showed special characteristics between samples. And the change of ginsenoside to the process of red ginseng, cultivated ginseng and cultivated wild ginseng were showed different aspect.
