摘要
The purpose of this study was to analyze the correlation between the external, internal and chemical quality characteristics of 6-year-old red ginseng produced in punggi area. Red ginseng samples are graded as cheon (1st grade), ji (2nd grade), yang (3rd grade), gi (out of grade) by trained inspectors. External characteristics of red ginseng depend on weight, volume, density, length and color. Internal characteristics were expressed by length and occurrence ratio of inner white and inner cavity. Chemical characteristics were evaluated by crude saponin, ginsenoside (Rg1, Rb1, Rc), total sugar, acidic polysaccharide, and 50% ethanol extracts contents. Overall, this study showed that quality of external and internal characteristics was matched with grade, but chemical quality was not matched.
