Abstract
|
|
|
This study was carried out to get basic informations that can be used in quality control for processing ginseng products and also in separation of pure ginsenosides for experimental purpose. The composition of various parts of 6 year-old ginseng was 4.1% of rhizome (node), 47.7% of main root, 34.1% of lateral root and 14.1% of fine root on dried weight basis. The weight ratios of epidermis-cortex and xylem were about 1:1 in main root and about 2:1 in lateral root. The distribution of total saponin content shows 29.2% in main root, 34.6% in lateral root, 29.1% in fine root and 7% in rhizorr but the order of the content per unit weight was fine root > rhizome > lateral root > main root. Total saponin content according to age of root was increased gradually within 3% for 6 years, as compared with two year old root.
In view of the increase of root weight owing to the net amount of saponin in root in-creased continuously.
The increase rates of total saponins per year were 3.1, 12.3, 19.8, 43.8 and 21.1% in 2, 3, 4, 5 and 6 years-old ginseng root, respectively.
