To investigate the effect of NaCl concentration on plant growth in three halophytes, Suaeda asparagoides, Suaeda maritima, and Salicornia herbacea, and to select afforestation species for reclaimed land along the shore, this experiment was conducted by ebb and flow system added fertilize of 1/2 Hoagland solution and halophytes were cultured for 4 month treated by 0, 50, 200, 400 mM NaCl, respectively. The shoot height was increased with 0 and 50 mM NaCl treatment of Suaeda asparagoides and Suaeda maritima and decreased with 200, 400 mM NaCl treatment, whereas them of Salicornia herbacea was increased by 200 mM NaCl treatment. The higher NaCl concentrations, the lower fresh and dry weight in Suaeda asparagoides. In case Suaeda maritima and Salicornia herbacea, fresh and dry weight was increased by 200 mM NaCl treatment. The higher NaCl concentrations, the lower chlorophyll contents in shoot of all treatment. The proline contents of 400 mM treatment in Suaeda maritima was higher than them of other treatments. The shoot water potential was generally lower in 50mM as compared to the control in Suaeda asparagoides, Suaeda maritima, significantly.

This study investigates the effect of Salicornia bigelovii extract on the activities of antioxidant, anti-wrinkle and whitening. Among amino acids, the glutamic acid concentration was the highest with an order of proline > alanine > $\gamma$-amino-n-butyric acid > arginine. The total polyphenol concentration and antioxidant activity were an order of ethyl acetate extract > n-butanol extract > hexane extract > hot water extract > ethanol extract. Especially, when ethylacetate was used as extractant, the total polyphenol concentration and antioxidant activity were 31.6 mg/mL and 82.6%, respectively. The inhibition activity of tyrosinase was increased with the increase concentration of ethylacetate extract. Especially, when the extract concentration was increased from 20 to 100 mg/mL, it was raised from 15.2 to 98.2%. In the case of inhibition activities of elastase, and collagenase, they were also increased with the increase concentration of ethylacetate extract. When the extract concentrations were increased from 20 to 100 ug/mL, they were enhanced from 2.9 to 32.5% and from 3.8 to 29.7%, respectively. The results show that the ethyl acetate extract of Salicornia bigelovii can be applied as sources for functional cosmetics and pharmaceuticals.

Tungtungmadic acid(3-caffeoyl, 4-dihydrocaffeoyl quinic acid: CDCQ) is a new chlorogenic acid derivative isolated from the Salicornia herbacea. The suppressive effects of CDCQ on the progress of acute carbon tetrachloride($CCl_4$)-induced hepatic fibrosis were investigated in mice. CDCQ significantly suppressed $CCl_4$-induced hepatic necrosis and inflammation, as determined by serum enzymatic activities of alanine and aspartate aminotransferase and serum TNF-$\alpha$ levels in a dose-dependent manner. In addition, increased hepatic lipid peroxidation and fibrosis after acute $CCl_4$ treatment were suppressed by the administration of CDCQ. CDCQ also significantly prevented the elevation of hepatic hydroxyproline and collagen content and ${\alpha}$-smooth muscle actin(${\alpha}$-SMA) expression in the liver of $CCl_4$-intoxicated mice. These results suggest that the suppressive effects of CDCQ against the acute $CCl_4$-induced hepatic fibrosis possibly related to its ability to block both hepatic inflammation and the activation of hepatic stellate cells.

Soybean powder is a readily-available food ingredient. Furthermore, saltwort powder is an herb with various physiological effects. Therefore, in this study we examined the physiochemical characteristics of soybean dasik prepared with 0, 4, 8, and 12% saltwort powder. We measured Hunter's color values, mechanical characteristics, and sensory qualities. The result of each analysis is as follows. There were not significant differences between the moisture content of the control group and the groups with saltwort powder. The ash content increased while the fat and protein content decreased as the ratio of saltwort powder increased (p<0.001). In the analysis of color differences, the L, a, and b values decreased as the ratio of saltwort powder increased (p<0.001). The hardness (p<0.001) of the groups increased as the ratio of saltwort powder increased, but adhesiveness decreased. Sensory evaluation data showed that softness, hardness, and chewiness decreased while color increased as the ratio of saltwort powder increased. Finally, aroma, sweet taste, nutty taste, and overall acceptability was shown to be best for the 4% addition group.

A study on vegetation in the Mangyeong River and Dongjin River basins and the surrounding regions of the Saemangeum Reclaimed Land was conducted in a series of efforts to determine the expected ecological changes in the salt marshes, to restore their vegetation, to explore the restoring force of halophyte, to examine the community mechanism and, ultimately, to rehabilitate marshy land vegetation along the lakeside, coastal dune and salt marshes of the Saemangeum Project Area. The findings of the study may be summed up as follows: Five species such as Suaeda japonica, Salicornia herbacea, Atriplex gmelini, Aster tripolium and Suaeda asparagoides that are mostly distributed in the estuary of the Saemangeum Reclaimed Land were analyzed to examine the mechanism of halophyte to maintain their community. To find out the strategies of plants for survival and the cause of forming community structure, a research was made as for appearance ratio of young sapling. From the results of laboratory analysis into dynamics of the saplings of halophyte, it was revealed that the germination ratio of the dry area and submerged area decreases in the order of Suaeda asparagoides, Suaeda japonica, Salicornia herbacea, Atriplex gmelini and Aster tripolium.

Tungtungmadic acid (3-caffeoyl-4-dihydrocaffeoyl quinic acid) is a new chlorogenic acid derivative that was isolated from the Salicomia herbacea. The structure of tungtungmadic acid was determined using chemical and spectral analysis. The antioxidant activity of tungtungmadic acid was evaluated using various antioxidant assays, including free radical scavenging, lipid peroxidation and hydroxyl radical-induced DNA strand breaks assays. Tungtungmadic acid ($IC_{50}\;=\;5.1\;{\mu}M\;and\;9.3\;{\mu}M$) was found to have higher antioxidant activity in the DPPH scavenging assay as well as in the iron-induced liver microsomal lipid peroxidation system. In addition, the tungtungmadic acid was also effective in protecting the plasmid DNA against strand breakage induced by hydroxyl radicals.

To get basic data for the utilization of S. herbacea L. as a raw material in food and Chinese herbs, chemical compositions of its leaves, stem and root were investigated. Leaves had the highest level of moisture and the lowest bevel of total sugar. The crude protein and crude lipid contents of the stem were similar to those of the root. Crude ash and salt contents (dry basis) in leaves were considerably higher than those of the stem and root. Total amino acid contents of leaves, stem and root were 1,270 mg/100 g, 1,525 mg/100 g, and 1,569 mg/100 g, respectively. Although the amino acid compositions of loaves, stein, and root were different, their major amino acids were glutamic acid, leuicine, isoleucine and aspartic acid. The rich minerals in leaves, stem and root were Na, K and Ca.

Chenges in respiration of the soils collected from the reclaimed tidal soil in Chogi-ri, Kanghwa Island and treated with organic matters are presented. The measurement of the respiration for the smaples, which were incubated for 0,2,4 and 5 weeks, were carried out by using Warburg's respirometer. While the respirations of the samples added by organic matters were increased 6.7 - 28.0 times compared with that 0 week during the incubation in case of 5-year soil, the respiration in case of 3-year soil were increased 3.3-11.8 times. Thus, the effect of adding organic matters on the respiration of the experimented soils, as this indicates, was much higher for the soil of 5-year area than that of 30-year area. And for the organic matters Salicornia was most effective and then Suaeda and Oryzae. The samples treated with Salicornia and Suaeda showed their highest respiration rate at the 4th week, but the one with Oryzae was measured to increase progressively during 5 weeks experimented. Regarding the salinity, content of organic matters and number of bacteria, in each intact soil experimented, 5-year soil samples had much poor habitat then 30-year soil for the activity of soil microorganisms, but according to the result mentioned above, it is firmly believed that the addition of organic matters on the saline soil is one of the best means to change the reclaimed tidal land into arable land with less time duration.
