Two herbal medicines of the Polygonatum genus, namely Polygonati Rhizoma and Polygonati Odorati Rhizoma, are difficult to distinguish from each other through exterior morphologic aspects. Furthermore, because the standard components for physiochemical distinction have not yet been standardized, the identification of these medicines through botanic taxology is based on genetic methods of random amplified microsatellite polymorphism (RAMP). For the RAMP evaluation, we used five sets of UBC microsatellite primers 811, 818, 834, 836, 842 and random primer M1. Although no specific band that could clearly distinguish Polygonati Rhizoma from Polygonati Odorati Rhizoma was found, 11 Polygonatum plants could be divided into two groups by this method. P. sibiricum and P. stenophyllum were classified to group I and the others were to group II. As P. sibiricum and P. stenophyllum were very similar in genetic and morphologic perspective, the results suggest that P. stenophyllum belongs to the Polygonati Rhizoma family.

As a result of the Four-River Restoration Project in Korea, the habitat of endangered plant species of Aster altaicus var. uchiyamae and Polygonatum stenophyllum, which had been natively grown in the riparian zone of Namhan River, was destroyed and artificial replacement habitats were created. In this study, Habitat Suitability Index (HSI) was used to determine whether the replacement habitats are suitable for each species or not. From October 2015 to July 2016, Habitat Evaluate Procedures (HEP) were conducted on two replacement habitats of A. altaicus var. uchiyamae (Gangcheonsum and Sum-River) and on two replacement habitats of P. stenophyllum (Gangcheonsum and Youngjuk) in the Namhan River watershed. As evaluation parameters for A. altaicus var. uchiyamae habitat, habitat matrix (ratio of unburied gravel), height above the ordinary water level, soil nutrients, and light conditions were selected and for P. stenophyllum habitat, soil texture, light conditions, and coverage of companion species were selected. HSI was applied to evaluate the suitability of each replacement habitat. According to the result of the evaluation, replacement habitats of A. altaicus var. uchiyamae and P. stenophyllum located in Gangcheonsum have relatively high HSI values as 0.839 and 0.846, respectively. On the other hand, replacement habitats of A. altaicus var. uchiyamae in Sum-River and P. stenophyllum in Youngjuk zone have HSI value of 0, indicating unsuitable habitats for these species. This is the first attempt to apply HSI for plant species in Korea and proved the usefulness of HSI on plants.

This study was carried out to search for natural anti-oxidants and anti-inflammatory compounds from 5 medicinal plants (Carthamus tinctorius seed, Cyperus rotundus, Schizonepeta tenuifolia, Polygonatum odoratum var. pluriflorum, and Paeonia lactiflora). These plants were extracted with 70% ethanol. In order to measure total antioxidant activity of flavonoids, polyphenol content was measured. Radical scavenging activities of extracts were examined using a-a-Diphenyl-${\beta}$-picrylhydrazyl ($DPPH{\cdot}$), 2,2-azino-bis 3-ethylbenzthiazoline-6-sulfonic acid ($ABTS{\cdot}$), ferric reducing antioxidant power (FRAP) and superoxide anion radical assays. C. tinctorius seed extracts showed the highest polyphenol and flavonoid contents as well as strong $DPPH{\cdot}$, $ABTS{\cdot}$, FRAP, and superoxide anion radical scavenging activity. Also, C. tinctorius seed extracts showed the highest nitric oxide (NO) production inhibitory effect. Theses results indicate that the C. tinctorius seed extracts can be used as a functional material due to their effective anti-oxidative and antiinflammatory activities.

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.

The leaves of Duchung(Eucommia ulmoides), an oriental medicinal plant, have a peculiar aroma of Chinese medicine and astringent taste, which make the consumer be reluctant to Duchung leaf tea. Therefore, the purpose of this study was to develop a mild flavored Duchung leaf tea by mixing with other plants. The flavor patterns of developed tea were analyzed using an electronic nose. Polygonatum odoratum and Elsholtzia splendens were used for improving the flavor of Duchung leaf tea. The addition of 20, 30 and 40% of Polygonatum odoratum improved the overall acceptance in hedonic sensory evaluation. The flavor pattern of the tea was described by principal component analysis(PCA) and the resistance ratio(R/cub gas/R$\_$air/) of sensors. The PCA plot was also used to explain the mild flavor of the tea, which was extended from the right side(positive value of the first principal component) to the left side(negative value). Analysis by using an electronic nose with metal oxide sensors could be applied to detect whether mixed Duchung leaf tea was acceptable or not.

Low-fat and sugar-free (LFSF) cookies were developed for patients with metabolic syndrome X, such as obesity, diabetes, coronary heart disease, and hypertention, using artificial sweeteners (mixture of aspartame and saccharin), pectin and herb extracts such as Polygonatum Odoratum (Mill) Druce, Schizandrae Fructus and Lycii Fructus, without sugar and fats. LFSF cookies were composed of 7.5 : 1 of aspartame and saccharin, 5% pectin, 49% protein, and 5% herb extracts, with reduced fat level. The values for area under the curve in oral glucose tolerance tests were significantly lower in 90% pancreatomized-(Px, n = 8) and sham - operated (Sham, n = 8) rats which consumed LFSF cookies, than the control, which consumed regular cookies. Blood glucose levels were higher and the peak levels were significantly lower in the LFSF cookies group than the control group of Px and Sham rats. Blood glucose levels of healthy female college students (n = 10) at 30 and 60 min after the consumption of 30 g LFSF and regular cookies were not different, but they were significantly lower in the LFSF-cookies group in diabetes patients (n = 10). In conclusions, LFSF cookies was considered as a good snack for diabetic patients.

Present experiments are conducted to study the seed viability and optimum germination temperature of Polygonatum odoratum var. pluriflorum that is known to have low germination ability and long germination duration. To enhance germination rate, various growth regulators and inorganic salts were employed. Low germination rate was obtained with 4 year old seeds, but not with $1{\sim}2$ year old seeds. The seeds germinated very well under $22{\sim}25^{\circ}C$ and germinated speed was rapid. Especially, $1{\sim}2$ year old seeds germinated at $25^{\circ}C$ showed $70{\sim}71.2%$ germination rate. Priming treatments using $GA_3$, IAA, NAA, kinetin, $KNO_3$, $KH_2PO_4$, $Ca(NO_3)_2$ were effective compared to control except BA. 1 year old seeds treated with $GA_3$ 0.5 mM and IAA 1 mM showed 96% and 93% germination rate, respectively.
