Abstract
|
|
|
Objectives: This study aimed to examine the changes in ingredients according to its cultivation method by examining the content of saponin and non-saponin components of ginseng.
Methods: Ginseng saponin component analysis was compared and reviewed using the high-performance liquid chromatography method, and acidic polysaccharide component was measured using the carbazole sulfuric acid method.
Results: The comparative analysis of ginseng saponin content of 4 and 6 years old fresh ginseng showed the following results. According to the cultivation method, upland field cultivation fresh ginseng showed higher average content of crude saponin than paddy field cultivation fresh ginseng. Whereas, paddy field cultivation fresh ginseng showed higher average content of total saponin than upland field cultivation fresh ginseng.
Ginsenoside Rb1 showed higher content of paddy field cultivation fresh ginseng than upland field cultivation fresh ginseng in 6 years old ginseng. However, it showed higher content of upland field cultivation fresh ginseng than paddy field cultivation fresh ginseng in 4 years old ginseng. Additionally, ginsenoside Rg1 showed higher content of paddy field cultivation fresh ginseng than upland field cultivation fresh ginseng in 6 years old ginseng, whereas upland field cultivation fresh ginseng showed higher content of paddy field cultivation fresh ginseng in 4 years old ginseng. The effect on the content of ginseng saponins and acidic polysaccharides according to paddy field and upland field cultivation methods is considered to be small.
Conclusions: The paddy field cultivation method, which is more efficient in production cost due to depletion of farmland and long-distance cultivation, is considered to be an economical cultivation method.
