As a result of investigating the effect of Alismatis Rhizoma extract on the growth of microorganisms, as shown in Figures 2a, 2b, 2c, 2d, 2e, the growth of the bacteria was inhibited even by adding only 30 μl of the extract per 5ml medium. In addition, the growth of the bacteria was inhibited by 50% or more in almost all bacteria compared to the control.

As a result of investigating the morphological changes of the microorganisms according to the extract of the taxa extract, as shown in FIG. 3, after treating the taxa water extract with Salmonerlla typhimurium , the surface structure of the cells was severely compared with the control group. Seo et al. (Seo Kwon Il, Sang Won Lee, Ki Ho Ho: Korean Agricultural Products Conservation & Distribution Association (1999), 6 (1)), treated with cornus water extract in E. coli O-157 and observed by electron microscopy. It was reported that the cell membrane function was disrupted in the cells treated with the extract and the contents of the cells were leaked to the outside of the cells, thereby inhibiting the growth of the cells. It was reported that the structure was severely collapsed.These phenomena are also the result of the exposure of lysates or cell components due to the destruction of the cell wall and cell membrane of microorganisms by taxi water extract. I think.

Experimental Example 2: Investigation of Antioxidant Effect of Taxa Extract

The in vitro antioxidant and hepatic lipid peroxidation inhibitory effects on linoleic acid of Alismatis Rhizoma were investigated. In order to measure the antioxidant effect of taxa extract, 1 g of linoleic acid, 10 ml of ethanol, and a predetermined taxa extract were added to a Erlenmeyer flask, and 25 ml of 0.2 M phosphate buffer was added and stored at 37 ° C. for a period of time. Then, the reaction solution was transferred to a separatory funnel, and 25 ml of chloroform was added thereto, followed by extraction two to three times. 25 ml of acetic acid and 1 ml of saturated KI solution were added to the chloroform extract, which was allowed to stand in the dark for 5 minutes, and then 50 ml of distilled water was added and titrated with a 1/100 N Na ₂ S ₂ O ₃ solution. Taxi extract was added methanol, ethanol, and water extract, respectively, and BHT 0.1% was added and stored at 50 ° C. for 7 days to measure peroxide value.

A little higher than when added. In addition, as a result of measuring the peroxide value after adding the water extracts of the taxi water at the concentrations of 50, 100, 150 and 200 μl, as shown in FIG. 5, all of them were very low compared to the control, and when 150 μl was added, the peroxide until 5 days storage. This was hardly produced, which was about the same as adding 100 μl of 0.1% BHT. Kwon et al. (Kwon Oh-Geun, Son Jin-Chang, Sang-Chul Kim, Sang-Cheol Kim, Pyo-Sang, Park, Seung-Woo: Korean Society of Agricultural Products and Storage (1998), 5 (281)) showed that the antioxidant activity of linoleic acid in the ethyl acetate fraction of methanol extract was The comparison group reported that BHT was 96.2%, and Seo et al. (Seo, Kwon-Il, Sang-Won Lee, and Ki-Ho Yang: Korean Agricultural Products Storage and Distribution Association (1999), 6 (1)) showed that the extracts of linusic acid were 10, 30 and After adding 50 μl and storing at 50 ° C. for 7 days, the peroxide value was measured to be 42, 30 and 25 meq / kg compared to 187 meq / kg of the control, which showed a significant antioxidant effect. Addition of only μl showed significant antioxidant effect.

The TBA value of liver lipids in rats was 3597 μmol malondialdehyde (MDA) / g liver in the control group without the addition of taxa water extract as shown in FIG. 6, and the TBA value of the test groups to which the taxa water extract was added was 1443 μmol MDA / g liver. All showed lower anti-oxidant effect than the control.

As a result of measuring the proliferation of cells by the concentration of taxa extract to the splenocytes of the mouse by concentration, as shown in FIG. 7a, the concentration of the spleen cells of the experimental group treated with the extract was increased in a concentration-dependent manner as shown in FIG. 7A. Could. As a result of measuring B cell proliferation induction effect of taxa by separating only B cells contained in splenocytes, as shown in FIG. 7B, proliferation was increased in a concentration-dependent manner as in splenocytes, especially at a concentration of 1000 ㎍ / μl. It was found that there was an excellent synergistic effect.

As a result of investigating the effect of taxa extract on nitric oxide (NO) production of macrophage, as compared with the untreated control group, as shown in Table 2, the experimental group treated with taxa extract by concentration alone and LPS were treated together with LPS. None of the experimental groups induced carbon monoxide (NO) production in macrophages. However, the experimental group treated with 1ng / ml of IFN-γ showed a tendency to decrease slightly at low concentrations of the taxa extract, but it was found that the production of nitric oxide (NO) was significantly increased at high concentrations. In other words, it can be seen that the taxa extract has a synergistic effect on the production of nitrogen monoxide (NO) induced by IFN-γ at high concentrations such as 1000 µg / µl.
