The purpose of this study was to synthesize tasty and healthy solomon's seal coffee by combining solomon's seal and a coffee-making process. Therefore, this study was carried out to establish the most suitable conditions for coffee-making by surface response surface methodology. Using the center synthesis method, we synthesized solomon's seal coffee by considering three factors (solomon's seal, coffee, and temperature) and three levels. The sixteen experimental items for solomon's seal coffee based on surface-reaction analysis were scent (crust break-scent when pouring water in solomon's seal coffee, flavorscent when tasting solomon's seal coffee), taste (clean-cup-pure taste without loose scent, sweetness, and acidity), mouth-feel, aftertaste, overall quality, and other taste degrees. Scores were from 1 to 7, with 7 indicating the highest preference. The optimum mixing rates which meet sensory items were coffee 19.51g, solomon's seal 2.07g, and temperature $93.39^{\circ}C$. Based on the above results, solomon's seal seems to be well suited for coffee. It was also found that solomon's seal has great potential to be well suited with other foods.

The effects of Curcuma extract Solomon's seal (Polygonatum odoratum var. pluriflorum), and maltodextrose on acute hepatotoxicity in Sprague-Dawley (SD) rats were investigated. Acute hepatotoxicity was induced by 0.5 mL of carbon tetrachloride ($CCl_4$) per kg of SD rats, which was injected to them before administration of Curcuma extract or both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures. SD rats dose with Curcuma extract of 4 mg or 40 mg per kg per day significantly (p<0.05) reduced the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) after 7 days compared to the controls dose with water. Treatments of Curcuma extract with 4 mg per kg per day in SD rats significantly (p<0.05) reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) to 78.0%, 82.6%, and 76.3% after 7 days compared to the controls, respectively. The levels of AST and ALT in SD rats dose with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures or either alone had no significantly different (p>0.05) compared to the controls. Treatments of Curcuma extract combined with Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures was 'liked more' to the sensory scores for odor and flayer compared to the controls. It was considered that Curcuma extract combined with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures could be used to functional food for enhancement of health and consumer acceptance.

Vegetable soup has been reported to have anti-inflammatory, anti-oxidative and anti-cancer effects. In this study, five kinds of vegetable soup were developed using a new manufacturing process and compositional changes in raw material, and anti-cancer and immuno-stimulatory activities were evaluated. Cytotoxicity tests based on MTT assay revealed that all vegetable soups had strong inhibitory effects against CT26 mouse colon cancer cells, with soups including Solomon's seal being most effective based on comparison of $IC_{50}$ values. Apoptosis in response to vegetable soup was occurred by 3-5 fold on cancer cells compared to normal cells. Mouse splenocytes increased by 266-541% in response to addition of vegetable soup in an in vitro proliferation experiment. In co-culture with splenocytes and CT26 cancer cells, splenocytes increased by more than 280% in every vegetable soup treatment, while cancer cells decreased by about 60% and cytokines such as $IFN- {\gamma}$ and IL-12 were secreted from splenocytes in high levels only in response to vegetable soup including Solomon's seal. In conclusion, all vegetable soups developed in this study had anti-cancer effects, and vegetable soup including Solomon's seal showed the strongest anti-cancer and immuno-stimulatory effects. These results suggest that functionality of vegetable soup could be increased by changes in manufacturing processes and raw materials composition.

The viable cell of 60% drinking water among 25 drinking water served in restaurant of Daegu district showed above 100 CFU/mL which is sanitary standard of drinking water. The 50 CEO of restaurant considered drinking water served in their own restaurant as just safe and were very deficient in aware of sanitation about drinking water. Sensory quality of drinking water boiled with plant materials, such as barley, Cassia semen, corn, Buckwheat, Korean solomon's seal, Chamomile, Brown rice-green and peppermint was improved in color, taste, flavor and overall acceptability compare to marketed drinking water, respectively. Especially drinking water boiled with Korean solomon's seal was the best In overall acceptability. The number of total bacteria reached above $10^2 CFU/mL$ in marketed drinking water after 4 days storage at 10. But the growth of microorganism did not occur in boiled drinking water with Brown rice-green tea, Korean solomon's seal, barley, Cassia semen and com during storage for 10 days at $10^{\circ}C$, respectively. The number of total bacteria reached above $10^2 CFU/mL$ in marketed drinking water after storage for 1 days at $25^{\circ}C$. The growth of microorganism was accelerated in boiled drinking water with corn, Korean solomon's seal, barley, Cassia semen except Brown rice-green tea during storage far 10 days at $25^{\circ}C$, respectively.

The foliage of variegated Solomon's seal is excellent in cut flower arrangements. However, it has a restricted marketing period because the harvesting is limited in spring and summer. The increased interest requires the year-round production, thus techniques for dormancy breaking and forcing without low temperature treatment is needed. Therefore, experiments were conducted to d etermine whether gibberellic acid (GA) could break dormancy in variegated Solomon's seal. Thes prouting of dormant bud did not occur throughout the experiment when $GA_3$ $400mg{\cdot}L^{-1}$ was applied to dormant rhizomes as a soil drench. However, when plants were treated with a GA drench after scratch with razor blade or were given direct injection of GA, percent sprouting was increased up to 100 or 83.3%, respectively. However, because treatments with razor or syringe may damage internal organs, we tested another method, scarifying the rhizomes with sodium hypochlorite (NaOCl). Rhizome scarification with 4% NaOCl for 6 or 24 hours followed by drench of $GA_3$ $400mg{\cdot}L^{-1}$ increased the dormancy breaking percentage to 70 or 86.7%, respectively. Moreover, scarified and GA-treated rhizomes produced more leaves than untreated or GA-soil drenched plants in the glasshouse. These results showed the possibility of year-round production of variegated Solomon's seal foliage with rhizome scarification and GA treatments.

This study was carried out to establish the manufacturing formulation of tea-bag type garlic tea. In order to eliminate of garlic-specific odor and taste, the masking effect of various additives against garlic flavor was determined with sensory evaluation. Leaves of green tea, arrowroot and Solomon's seal were screened as highly effective auxiliary ingredients in garlic tea. When two materials among the selected three auxiliary materials were mixed the same percentage, overall flavor of garlic tea synergistically was enhanced. The optimum concentration of garlic powder and stevioside as a sweetener were 20∼30％ and 1％, respectively. Therefore, three types formulation of garlic tea was establish. When the color, turbidity and total solid concentration of three formulated garlic teas were compared with those of commercially available formulated green tea containing unpolished rice, the latter was more yellowish color and the former was more superior to turbidity and total solid concentration.

This reserch was carried out to investigate the nitrite scavenging abilities (NSA) of 7 kinds of tea extracts. Nitrites are used as additives of cured meat preperation and exist in plants, foods, and medicines, so we intake it very often easily. Nitrites can act with amines to produce nitrosamine which is known to be a carcinogen. It is known that the pH, concentration of amines, and amounts of nitrite are three important conditions of nitrosamine occurence. 7 kinds of tea used in this experiment were Persimmon tree (Diospyroo kaki Thiunb, Per.), Mulberry tree (Morus alba Linne, Mul.), Rubber tree (eucommia ulmoi-des Oliver, Rub.), Solomon's-seal (Bolygonatu Morr, Som.), Chicory (Cichorrium intybus L, Chi.), Sumach (Rhus javanica L., Sum.), Docwood (Cornus officinale Sieb, Doc.) and they were extracted with methanol (MeOH), ethyl ether (EtEt), ethyl acetate (EtAc), and also the extract existed in the aqueous layer II (Aq L. II) was used.

Solomon's seal (Polygonatum odoratum) seedlings raised through its seeds can replace the rhizomes impelling higher cost for transplanting, This experiment was done to determine the seed characteristics and the germinating processes to give some information on bulk production of seedlings using the seeds. The external or internal morphology of seeds or seedlings grown in lab. or greenhouse was examined mainly with stereomicroscope. The external shape of Solomon's seal seed was hard seed-coat and orthotropous ovule with linear type embryo stretching to the center of seed. Germination proceeded through the several steps. The lower part of seed embryo having the primordia of bulbil and roots first grew before the bulbil and roots was developed from the primordia. The lower part of embryo was enlarged toward the endosperm of seed as soon as seed germinated. Then epicotyl was formed on the apex of bulbil. The epicotyl was elongated after at least 6-week chilling treatment for breaking its dormancy and the first leaf shape was affected by light intensity given during seedling emergence. The bulbil was the first organ of the rhizome used as tea or herb medicine.

This study was designed to test the effect of Korean traditional teas on lipid levels in lead (Pb)-administered rats. Male rats were divided into normal, Pb-control (rb-Con) and Pb-water extract of traditional teas (green tea: GWE, persimmon leaf: PWE, safflower seed: SWE, Solomon's seal: SSWE) groups. Pb intoxication was induced by administration lead acetate (25 mg/kg. BW, oral) weekly. The extract was administered based on 1.26 g of raw traditional tea/g BWday for 4 weeks. Net weight gain and feed intake were significantly lower in the Pb-Con group than in the normal group, whereas they were tended to increase by traditional teas supplements. Both Plasma and hepatic total cholesterol and triglyceride concentration were lower in the traditional teas supplemented groups compared to the Pb-Con group. Plasma VLDL-cholesterol and LDL-cholesterol levels were significantly increased by Pb ad-ministration, whereas HDL-cholesterol concentration was significantly lower in the Pb-Con group than in the normal group. However, water extracts of green tea, persimmon leaf, safflower seed and solomon's seal supplementation improved changes of the plasma lipoprotein-cholesterol levels in Pb administered rats.
