| ABSTRACT |
|
When Ⅰ evaluated the component variation of Naesowhajung-tang by the three types of extraction method, and each type s effects on the gastrointestinal tract, I got the following results. 1. The output ratio of extracts made out of Naesowhajung-tang were not significantly different among 13.8% of water extract(Sample-Ⅰ), 13.5% of 50% ethanol extract(Sample-Ⅱ), and 15.6% of water extract by spray dryer(Sample-Ⅲ). 2. magnolol, honokiol, hesperidin, naringin, poncirin and glycyrrhizin Sample had the largest amount of the following contents: magnolol, honokiol, hesperidin, naringin, poncirin and glycyrrhizin. 3. All the extracts of Naesowhajung-tang showed the inhibitory effect on the smooth muscle contraction of the isolated ileum in mice and fundus-strip in rats induced by acetylcholine chloride and barium chloride. 4. High concentration Sample-Ⅱ was recognized to be effective in preventing gastric ulcers in Shay s rats, but not in the other rat group. 5. All the extracts of Naesowhajung-tang were recognized to be effective in preventing gastric ulcers induced by Ethanol-HCl in rats. 6. The increase of transport ability in the small intestine was recognized only when the concentration of all the samples was doubled, but not in the other concentrations. 7. The increase of transport ability in the large intestine was recognized only when the concentration of Sample-Ⅱ was doubled, but not in other concentration. Using the results mentioned above, I suggest that Sample-Ⅱ has more significant effects on the gastrointestinal tract than the others. |
