The objectives of this study were to select the seeds of Cucurbitaceae and Solanaceae genotypes in terms of superior with bioactive compounds content and to inform sophisticated data for developing the high value-added products. We evaluated to aspects of the antioxidant activity, polyphenol content, and flavonoid contents in seeds from two vegetable family. We used in the Cucurbitaceae(watermelon, squash, bitter gourd, and sponge gourd) and Solanaceae(hot pepper, sweet pepper, and egg plant) the total 408 genotypes. In Cucurbitaceae, polyphenol content of watermelon and squash genotypes were ranged 19.9-343.8 and $6.1-81.2mg{\cdot}100g^{-1}\;DW$, respectively. The polyphenol content of watermelon genotypes was 12% among all genotypes over $160mg{\cdot}100g^{-1}\;DW$. The mean of flavonoid content in watermelon and squash genotypes represented 80 and $41.3mg{\cdot}100g^{-1}\;DW$, respectively. In Solanaceae, flavonoid content of hot pepper genotypes was ranged $64.4-472.5mg{\cdot}100g^{-1}\;DW$, with an average of $165.0mg{\cdot}100g^{-1}$. The 23 hot pepper genotypes were classified over 90% antioxidant activity. The antioxidant activity of sweet pepper was ranged 35.9-90.3%, and 23% of all genotypes represented 82% antioxidant activity. The polyphenol and flavonoid content of egg plant was ranged $38.1-642.0mg{\cdot}100g^{-1}\;DW$ and $14.2-1217.0mg{\cdot}100g^{-1}\;DW$, respectively. In addition, we selected that 8 egg plant with the superior genotypes for antioxidant activity, polyphenol, and flavonoid content. Results revealed that there was significant variation of antioxidant activity and bioactive compounds contents in both vegetable famaily. In addition, we suggested that selected genotypes seeds with high contain bioactive compounds will be more efficiency to develop natural value-added products.

To characterize plant root-associated bacteria in wild plant family Solanaceae, Solanum nigrum L. plants were collected in Dokdo island. Forty four strains of nitrogen-fixing or spore-forming bacteria were isolated from rhizosphere of Solanum nigrum L. plants. Among these, 19 strains were able to produce auxin. Thirteen strains of these produced siderophore as determined by color reaction on CAS-blue plate, 8 strains were able to solubilize phosphate. The 16S rDNA genes of the isolated bacteria were amplified and sequenced. Model plants, pepper and tobacco, were established in order to evaluate the bacterial capacities eliciting growth promotion and induced systemic resistance. The plants treated with strain KUDC1009 were more resistant and capable of growth-promotion than control plants when challenged by either Xanthomonas axonopodis pv. vesicatoria or Erwinia carotovora sub. carotovora strain SCC1. Rhizobacteria isolated from Dokdo island can promote growth of wild type Solanum nigrum L. under much environmental stresses.

The activity of the lipase and phospholipase extracted from the seed meal of Nicotiana tabacum L. was studied with the help of Spectrophotometer at different pH, Temperatures and Solvents. Both lipase and phospholipase shown optimum activity at pH 6 and $45^{\circ}C$. Their activities also maximize when n-heptane was used as solvent media.

The lipid classes constituents; hydrocarbons, wax esters, sterol esters, triacylglycerols, free fatty acids, 1,3-diacylglycerols, 1,2-diacylglycerols, free sterols, 2-monoacylglycerols, 1-monoacylglycerols, phosphatidylethanolamines, phosphatidylcholines, lysophosphatidylethanolamines and phosphatidylinositols of Nicotiana tabacum L. seeds oil were investigated by thin layer and gas chromatography. Palmitic, oleic and linoleic acids were the major components in all lipid classes studied.

The plants medicinal resources of Mt. Eb-aon were investifeted 18times from JuLy, 1988 to August, 1989. In orther to analyze the vegeta-tion of Eb-am mountain area, medical wild plants structure and distr-ibution. Medical wild Plants of Eb-am mountain consisted of 100 familis, 337 species in alL. The resources of important herb drugs were, Graminea, Liliaceae, Molaceae, Polygonaceae, Ranunculaceae, Brassicaceae, Rosaceae, Drupaceae, Fabaecae, Apiaceae, Labiatae, Solanaceae, Scrophulariaceae, Rubiaceae, CampanuLaceae, ComposLtae, The herb drufs were Comparatively more than in other mountains in our country.

Withametelin, a steroidal compound isolated from leaves of Datura metel L.(Solanaceae), showed antifungal activity against some plant pathogenic as well as saprophytic fungi tested in vitro. Except Curvularia maculans and Colletotrichum sp., spore germination of all the other 23 fungi was inhibited significantly at 125 to 1000 ppm. Out of the 25 fungi tested, Curvularia sp., Cercospora abelmoschi, Heterosporium sp., Erysiphe cichoracearum and Ustilago cynodontis were most sensitive as there was complete inhibition of germination at 1000 ppm. Similarly, spores of Alternaria brassicae, Curvularia lunata and Helminthosporium pennisetti showed less than 3% germination at the same concentration. Rest of the fungi showed more than 15% spore germination at the same concentration.

Thirtyfour species of Korean medicinal plants which have been frequently used in oriental herb prescriptions were evaluated on their cytotoxicity and potential antitumor activities against AC glioma(9 ASK) in vitro. Dose of $100{\mu}g/ml$ of plant extracts appeared to exhibit slight cytotoxicity. Seven plant extracts, Aralia continentalis(Araliaceae), Lycium chinensis(Solanaceae), Epimedium koreanum(Berberidaceae), Platyodon grandiflorium(Campanulaceae), Pleuropterus multiflorus(Polygonaceae), Rheum undulatun(Polygonaceae) and Scutellaria baicalensis(Laminaceae), exhibited significant reversal$(51{\sim}90%)$ of astrocyte formation into original neuroglial cells' morphology through the prescreen tests.

Korean folk medicine 'GaJi' has been used to treat a boil, cough, mushroom poisoning and stomach cancer. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of 'GaJi', the morphological and anatomical characteristics of the stems of Solanum species growing in Korea, i.e. S. japonense Nakai, S. lyratum Thunb., S. melongena L., S. nigrum L. were compared. As a result, it was determined that GaJi was the stem of Solanum melongena L.

Solanum lyratum(Solanaceae) has been used as a traditional analgesic, antipyretic and hepatoprotective agents in Korea. In this study, we investigated the hepatoprotective effect of ethylacetate extract of Solanum lyratum (SL) on the dimethylnitrosamine (DMN)-induced liver damage in rats. Oral administration of SL (150, 300 mg/kg daily for 4 weeks) into the DMN-treated rats remarkably prevented the elevation of serum alanine transaminase, aspartate transaminase and alkaline phosphatase levels. SL also increased serum protein level and reduced the hepatic level of malondialdehyde in DMN-treated rats. Furthermore, DMN-induced elevation of hydroxyproline content was reduced by the treatment of SL. In conclusion, these results demonstrated that SL exhibited in vivo hepatoprotective effect against DMN-induced liver injury, and suggest that SL may be useful in the prevention of liver damage.
