추출조건에 따른 인삼중의 Ginseng Extract 와 Saponin 함량변화에 관한 연구

In order to investigate the optimal conditions which affects to extraction of ginseng extract and saponin in ginseng extract, experiment was carried out varing with ethanol percentage, extraction time, temperature, solvent and plant parts. The results are as follws: 1. The amounts of ginseng saponin was increased according to increanation of ethanol percentage while the amounts of ginseng extract was decreased. 2. The amounts of ginseng extract was increased as the prolongation of extraction time, on the other hand, ginseng saponin contents increased until 40hr. and decreased after that. 3. By the raise of extraction temperature, both of the amounts of ginseng saponin and ginseng extract was increased two times and four times, respectively. 4. The total amounts ginseng extract was obtained 22.86% when the water used as the extraction solvent, 11.28% on ethanol and 11.04% on methanol, in the order, and the saponin contents gained when the extraction solvents of water, methanol and ethanol 7.47%, 12.36% and 12.77%, respectively. 5. It showed 9.23% of ginseng extract in epidermis and 8.43% of ginseng saponin in tail part of raw ginseng and in the case of dried ginseng, ginseng extract and saponin showed the most amounts in epidermis of 18.28% and 19.35%, respectively. 6. The ratio of panaxadiol and panaxatriol contents of ginseng saponin was almost same when it was extracted varing with ethanol percentage and extraction time (duration), and the more alcohol percentage and the longer extraction time increased, the more fractional content of ginseng saponin was extracted.
