This study demonstrated the immunological effects of methanol extracts from Doenjang added with wild plants (Pteridium aquilinum and Aster scaber) on bone-marrow derived macrophages and mouse splenocytes. Doenjang (DJ) and wild plant added Doenjang (WPDJ) extracts were treated to bone-marrow derived macrophages (BMDM) and splenocytes, and cell proliferation and cytokine production were measured. Cell proliferation of BMDM and splenocytes was more highly elevated in the WPDJ-treated group compared to the DJ-treated group. Cytokine [tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6, IL-$1{\beta}$, IL-10, and IL-12] production in BMDM also significantly increased in the WPDJ-treated group. Similarly, in the case of cytokine production in splenocytes, WPDJ treatment highly increased production of Th 1 type cytokines [interferon (IFN)-${\gamma}$ and IL-2] but did not affect production of Th 2 type cytokines (IL-4). These results suggest that wild plants could improve the immunomodulatory activity of Doenjang and may be effective for the development Doenjang.

In mountainous regions, wild herbs which can also be edible in nature for humans and animals possess a wide array of biologically diversified properties. It is because of the fact that due to the cold weather of mountains; they are enriched in certain kinds of phytochemicals such as anti-oxidants, anti-inflammatory and many more. One such kind of an herb is Aster scaber (AS) in Korean. It is a widely cultivated culinary herb in Korean peninsula and used as a side dish in Korean culinary cuisine. In view of its extensive use in cuisine, we geared to unravel the anti-oxidant and anti-inflammatory effects of AS in murine alveolar macrophage cell line (MH-S). 2,2'-Azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) assays revealed a dose dependent (7.8~1,000 ㎍/mL) inhibition of oxidation by AS 70% ethanol (ASE) extract as compared to Trolox and Ascorbic acid respectively. Nitric oxide assay (NO) showed a dose dependent decrease (5~40 ㎍/mL) in MH-S cells with ASE when stimulated with Coal Fly Ash (CFA). Moreover, this dose for NO reduction was also found to be least cytotoxic for cells as determined by cellular viability (MTT) assay. The gene expression of pro-inflammatory mediators (iNOS and COX-2) and cytokines (IL-6 and IL-1β) and were also dose dependently inhibited by ASE in MH-S cells through RT-PCR. Therefore, in light of these findings, AS exhibited a strong anti-oxidant and anti-inflammatory agent. These results also justify the extensive use of this mountainous herb in culinary practices for beneficial effects on human health.

In this study, we constructed a model of an area where the production and production amount of wild vegetables which are designated as short term income forest products for the whole country are self-sufficient for the representative Eastern Braken fern(Pteridium aquilinum)and Edible aster(Aster scaber). The difference between the existing cultivation site and the model result was examined, and the distribution of the cultivable area was simulated according to the near future climate change by the 2050s. The degree of agreement between the cultivated area and the actual native area was very low at 14.5% for Eastern Braken fern and 12.9% for Edible aster. Using the Maxent model, which has already been proven by many research examples, the cultivation maps through the model can guarantee statistical accuracy by considering many variables. To analyze future location changes, the RCP 4.5 scenario and the RCP 8.5 scenario were applie Edible aster d to predict potential future cultivable areas and compare them to the present. There was no decrease in the cultivable area due to climate change nationwide. However, in the RCP 8.5 scenario for Eastern Braken fern and the RCP 4.5 scenario for Edible aster, declining areas such as Gangwon-do, Jeollabuk-do and Gyeongsangbuk-do showed prominence according to the scenarios. The result of this study suggests that various models can be used for the production of short-term forest productivity maps and it will be used as a climate change impact assessment data for competitive forest products considering the influence of future climate change.

The photosynthetic rate (LPS)in the field was higher in the non-shading condition than in the shading. The fertilizer application was somewhat higher than non-fertilizer application. After humus application at 50% sading condition the growth and LPS increased with Ligularia fischeri. The maximum LPS at 80% shading was 22.3${\mu}{\textrm}{m}$mol/m/s with N-fertilizer application . Except Aster tataricus and Solidago virge-aurea. var. asiatic where the maximum LPS at non-shading and N-fertilizer application were 38.68 and 35.28${\mu}{\textrm}{m}$mol/m2/s. While the maximum LPS of Aster scaber was 30.01${\mu}{\textrm}{m}$mol/$m^2$/s at non-shading and non-fertilizer application. the growth rate was higher shading and fertilized conditions than non-shading and non-fertilized . The most effective shading condition was 50% , but leaf ration was highest in the 80% . But a. tataricus was favorable at non-shading and N-feritlized conditions.

This study were focused on the genetic relationship using RAPDs and some morphological characteristics among eleven taxa Aster collected in Korea. Twenty random primers were selected, a total 216 DNA bands were generated and 213 bands were shown polymorphism among species. The collected eleven taxa were clustered into five groups at 0.609 similarity index. The first group was A. glehni, A. ageratoides, A. maackii and A. scaber was clustered at 0.713 of genetic distance. The second group was A. tataricus and A. koraiensis and the third group was A. spathulifolius, the forth group was A. yomena, A. hayatae and A. hispidus and the fifth was A. tripolium.

This study was conducted to evaluate the antioxidative potentials of 4 Aster species. Flowers and aerial parts were extracted with 80% ethanol, and antioxidative activities and bioactive substance contents were investigated. Flowers showed higher extraction yield than aerial parts of all 4 species used. Among the samples tested, Flowers of A. scaber were found to be the most effective in both DPPH and ABTS radical scavenging assay. However, $Fe^{2+}$ chelate effect of all samples were lower than EDTA. Four samples(A. scaber flowers, A. sphathulifolius aerial parts, A. koraiensis flowers, A. scaber aerial parts) out of eight showed stronger inhibitory activities against linoleic acid oxidation than BHT at 8 days. Total polyphenol and flavonoid contents of A. scaber flowers(90.46 and $75.36mg{\cdot}g^{-1}$) were the highest, and followed by A. sphathulifolius flowers.

Cultivation of a native wild vegetable, Ligularia fischeri, is hampered by Phytophthora sp. Infected plants showed wilt and eventual death due to rots on the root and basal portion. Eight isolates collected were all identified as P. drechsleri based on their mycological characteristics. The fungi showed relatively strong pathogenicity to L. Fischeri, mild to Aster scaber and Codonoposis lanceolata, and none to Circium setidens and Pimpinella brachycarpa. This is the first report of Phytophthora root rot on wild vegetables in Korea.

Seven species of Umbellifer-plants and five Compositae-plants were examined for the presence of polyacetylenic compounds. By using the UV-and IR-spectrometric technique combined with preparative T.L.C., the presence of polyacetylenic compounds was identified in Heracleum moellendorffi $H_{ANCE}$ and Aster scaber $T_{HUNBERG}$.

This study was conducted to evaluate the effect of locations and nursing days on the cstablishment and the first-year growth of Aster scaber seedlings in mountainous areas. Survival rates of the seedlings ranged from 72% in Bukbang to 27% in Mt. Yeonyup B. Survival rate of 90 days-seedlings was 65%. 150days-and 120days- seedling had 2 or 3 leaves but it was almost same as that of native plants. The plants grown in Mt. Yeonyup A averaged 10.7cm high and 90 days-seedlings grew best. Dry weight of plants grown from 120 days- and 90days- seedlings was respectively 215mg and 205mg.
