This research was conducted to investigate the possibilities of usage of germinated-buckwheat (Fagopyrum esculentum
) by examining antioxidative, antimicrobial and cytotoxic effects of extracts from different germinated root length of buckwheat. Antioxidant activity
was shown higher in extracts of non-germinated seed
and root length 10 mm
, 2 mm
, 5 mm
as a synthetic antioxidant. In antimicrobial activity, non-germinated and germinated seeds were formed inhibitory zone against S. aureus
, P. aeruginosa
at the concentrations of
but B. subtilis, E. coli and S. typhimurium were not apparent antimicrobial activity. Extracts of germinated seed also decreased their antimicrobial activity compared to non-germinated seed extract. In addition, the growth of Calu-6 was inhibited of both 5 mm root length germinated and non-germinated seeds
as 95.12% and 87.15%, respectively, but these did not show any influence on cytotoxic effect against MCF-7 and Caco-2 cell lines. Extracts of 2 mm and 5 mm germinated seeds were also inhibited against Calu-6 and SNU-601 cell lines.

This study was carried out to investigate drying methods for keeping freshness and active components of aerial part of Saururus chinensis. Chopped samples were prepared using hot air drying, hot air drying + roasting, presteamed + hot air drying, freeze drying, and sun drying. Drying time was shorter
in hot air drying and freeze drying than in sun drying. Percentage of dry matter was higher in the order of freeze drying > sun drying > hot air drying, and moisture content in the order of sun drying > hot air drying > freeze drying. The contents of total phenolics and quercetin related substances were greater in the order of freeze drying > hot air drying > sun drying, while were decreased due to treatments before or after hot air drying. Electron donating ability (EDA) was highest in freeze drying, and showed a little difference between hot air drying and sun drying, but was increased because of treatments before or after hot air drying. In color values, the a value was lower in the order of freeze drying < hot air drying < sun drying. The contents of active components of plant parts of hot air dried were higher in the order of flower >leaf > chopped sample > stem. EDA showed similar tendency with those. The a value was lower in the order of leaf < chopped sample < flower < stem. As a result, freeze drying of chopped samples or hot air drying of leaf and flower were effective to maintain qualities of aerial part of Saururus chinensis.

This study was carried out to investigate the distribution and habitat characteristics of Boehmeria for utilization and conservation plan of natural agro-plant resources in South Korea. The native habitat of B. longispica Steud., B. platanifolia Fr. et Sav., B. spicata Thunb., and B. tricuspis var. unicuspis Mak. were distributed nearly all areas in South Korea. B. nivea Gaudich. was distributed south of Chungnam but B. pannosa Nak. et Sat. and B. sieboldiana Bl. were partially distributed toward the southern part in South Korea. The average number of plant species growing with Boehmeria in natural habitat was found 124.9 species and Artemisia princeps var. orientalis Hara showed the highest importance value among neighbor species. B. platanifolia Fr. et Sav. and B. spicata Thunb. were the most commonly neighbor species growing with Boehmeria in rate of 49%. Average yearly precipitation and temperature of habitat for Boehmeria were 1100 mm to 1390 mm and
respectively. Soil characteristics of habitat for Boehmeria. were that pH was 5.3 to 7.2 and B. nivea Gaudich. was higher content of organic matter than the other Boehmeria. Content of K and Na were similar among Boehmeria.
, Ca and Mg were shown a little difference among seven species.

Planting of peony, a perennial herb is usually planted in fall but the planting time can be postponed to next spring for other benefit such as land use, labour diversification and etc. This study was carried out to know the effect of planting time in spring on growth and yield of peony. Sprouting date in first year growth was earlier as planting time was later. Planting on March 10 showed best both top part and root growth and planting after that time resulted in worse growth. In planting on April 10, missing plant rate was 24% and accordingly root yield decreased to 43% comparing with that of March 10. Planting on March 10 resulted in thick and large number of root and so yield per l0a was 635 kg, the highest value among the other planting time in spring. The paeoniflorin content was not different significantly by planting time. These results suggested that March 10 was most appropriate for planting time in spring.

One of micropropagation methods was investigated by using a multiple-shoots protocol. Multiple shoot formation was obtained from excised axillary buds of Hypericum erectum on half-strength or basal MS medium supplemented with TDZ or BA. The optimal combination of shoot multiplication for the production of more shoots with a suitable size was MS medium supplemented with
TDZ (6.5 adventitious shoots per node). In vitro rooting was carried on half-strength MS medium with
IBA treatment. In addition, the rooted cuttings were showed a better root growth in the greenhouse and survived in more than 90%. The results show that the species can be micropropagated effectively by the application of axillary bud culture systems.

Korean Journal of Medicinal Crop Science, volume 14, issue 1, 2006, Pages 31~35
A protocol for plant regeneration from hairy root of Rehmannia glutinosa transformed by Agrobacterium rhizogenes ATCC15834 has been developed. Transgenic shoots were regenerated from hairy roots within 6 weeks after culture on the SH medium supplemented with 0.5 mg/l BA. Shoots were rooted on plant growth regulator free SH medium successfully. The transformed plants, which were regenerated from hairy roots, had thiner roots with extensive lateral branches, wrinkled leaves, shorter node, and grew faster compared with non-transformed plants. The biomass of the transformed plant was 1.28 g (F.W) per plant, significantly higher than the non-transformed plant (0.54 g F.W). The catalpol content in the transformed plant (0.56%) was also higher than that of the non-transformed plants (0.43%).

This study was carried out to investigate histological characteristics of Korean ginseng in steaming process. The Korean red ginseng were prerared with 6-years-old ginseng according to the steaming prcess and dried with
moisture and than cut in vertical section and horizontal section. The tissues are separated into epidermis, cortex, and xylem observed with Scanning Electron Microscope. The materials dried without steaming process contain cell membrane and crystallization of starch particle within them. But Korean red ginseng with prolonged steaming process are condensed, and the large hollows and cell membranes of vessel and resin duct are disappeared. In addition, Ca-oxalate rosette crystal is not found in the case of above 60-minute steaming time. The reason is that the tissues are condensed because of dry after elements' gelatinization.

Antioxidative and antibacterial activities of endemic plants extracts in Korea were investigated. Hydrogen radical scavenging activity was 99.72% in an elm tree, 99.725 in a Job's tears, 99.575 in an eggplant, and 94.025 in a barrenwort. Antibacterial activity of ethanol extract from 23 different species of wild plants were determined. The gull nut was showed the strongest antibacterial activities (16.0-19.0 mm) and also showed high antibacterial activities in a pine neddles, a gulmyungja, a wild ginger plants, a ginko (9.5-11.5 mm). Only extracts of Saurrranceae extract showed the antibacterial activity in Bacillus subtilus, Stapylococcus aureus, Escherichia coli, Samonella entetotidis. An antibacterial activities were showed weakly in an esungcho and an eggplant. A ground ivy showed Antibacterial activity on Stapylococcus aureus. A barren wort showed in antibacterial activity on Stapylococcus aureus, and E. coli. This results were suggested that many edemic plants resources contains antioxidative and antibacterial substances.
