Fields experiments were conducted to investigate the effect of various tillage depth (TD) on productivity and quality of C. auriculatum Royle ex Wight from 2005 to 2006. The length of vine was elongated in lower TD treatments as 50 cm longer in 10 cm TD than 30 cm TD, and stem diameter and dry weight had increased in the lower TD. Length, width, and weight of leaves showed the quantitive growth in the lower TD treatments, but the chlorophyll content had increased in the deeper TD treatments. Root number and length had increased in the deeper TD treatments, but the root diameter and decomposed root was increased in the deeper TD. The total yield of root showed the increasing tendency in the deeper TD treatments as 6.2 ton/ha in 10 cm TD and increased as
in the 20 cm TD treatments.

Some studies of dandelion have been carried out on bioactivities, however, no comparative analysis on antioxidant and cytotoxic activities in the Korean dandelion (T. coreanum NAKAI.; KD) and dandelion (T. officinale WEB.) have been reported. In this study, the extracts of KD and dandelion analyzed relative phenolic contents and free radical scavenging, antioxidant enzyme and cytotoxic activities. The extract of Korean dandelion leaves (KDL) exhibited a higher phenolics content (
) and a strong free radical scavenging activity (
value;87.89 ug/ml) than other parts and BHT (120.12 ug/ml), synthetic antioxidant. At ascorbate peroxidase (APX) activity, the dandelion root (DR) had a greater (38.8 U/mg protein) antioxidant enzyme compare to the dandelion leaves (12.2 U/mg protein). The catalase (CAT) and superoxide dismutase (SOD) followed higher enzyme activity in Korean dandelion root (KDR) than other parts. In a cytotoxic activity against human cancer cell, the extracts of KDR was found to be active against Calu-6, HCT-116, and SNU-601 cell lines, with
values of 522.34, 532.74 and 614.85 ug/ml, respectively. These results suggest that KD and dandelion would be an alternative antioxidant source, based on natural plant resources.

The chemical composition of the volatile constituents from the leaves and stems of endemic Acanthopanax koreanum and A. chiisanensis collected from Mt. Deokyu was determined by GC and GC/MS spectrometric analysis with the aid of NBS, Wiley Library and RI indice searches. The major constituents identified were
(31.34%), l-limonene (17.01 %),
(4.53%), trans-p-menth-2-ene-1,8-diol(3.13%), 1,8-cineole (4.73%), 1-dodecen-3-yne (2.64%) and (Z)-3,7-dimethyl-1,3,6-octatriene (3.21%) in A. koreanum, and
(14.78%), limonene (7.24%), t-ocimene (7.22%),
(7.72%), veridifloral (3.25%) and dodecane (2.44%) in A. chiisanensis.

Korean ginseng (Panax ginseng C.A. Meyer) is very difficult to obtain stable production of qualified ginseng roots because of variable stresses in soil environments. High salt concentrations in the ginseng nursery soil environment of Korea is one of important reducing factors for the stable production of quality ginseng. These studies were accomplished to identify the growth rate and production of ginsenoside from ginseng hairy root against NaCI. In the MS liquid culture, the highest contents and productivity of ginsenosides were appeared at 4 week after onset of the treatment of 0.1 M NaCI. And 0.24 M NaCI was more effective on the growth of ginseng hairy root under light condition than dark condition. Plants generally produce secondary metabolites in nature as a defense mechanism against pathogenic and insect attack. In this study, NaCI acts as a kind of stress as well as elicitor for production of ginsenosides.

We previously examined extracts, isolated from Scutellaria baicalensis (SB), chemical mediators, and IgE by mesenteric lymph node (MLN) lymphocytes in rats. The present study was to evaluate the effects of extracts of SB on the MLN lymphocytes function of mice given orally by 20 mg/kg for 2 weeks with dextran sulfate sodium (DS)-induced colitis. Results show that IgE levels in MLN lymphocytes was low, while IgA was high, in mice given SB compared to that fed water. Concentrations of
and interleukin (IL)-2 of T cells by concanavalin A treatment was significantly higher in the SB fed group than the normal group. Activation-induced IL-4 and IL-10 secretion was lower in SB fed mice compared control mice after DS-induced colitis. These results suggested that SB suppresses the inflammation in DS-induced colitis through the modulation of Th1/Th2 balance to down-regulate
response in MLN lymphocytes.

This study was carried out to elucidate the influence of gibberellin soak and seed dressing with Toros wp. on the dehiscence of Eleutherococcus senticossus seeds.
treatment was effective on promoting after-ripening seed of Eleutherococcus senticossus whose concentration was higher until
, after-ripening period became shorter. But rotting percentage increased gradually up above
was the most effective treatment for promoting after-ripening seed. Dressing treatment with Toros wp. on seeds reduced the dehiscent rate of E. senticosius. by suppressing activity of fungi living on the endocarp surface of seed.

This experiment was carried out to obtain the basic information on processing for product of high quality goods in Artemisia capillaris. We investigated antioxidant and antimicrobial activities by harvesting date and plant parts in Artemisia capillaris. Contents of total polyphenol compounds and flavonoids were the highest in leaf, followed by capitulum and stem. Leaf on June 30 contained 76.7 mg/g DW total phenolic compounds and 78.2 mg/g DW flavonoids. As
value, that was, the concentration of sample required for 50% reduction of DPPH (2,2-diphenyl-l-picrylhydrazyl) absorbance, was very low as
in leaf on June 30, antioxidant activity was the highest. In addition,
of BHA, BHT and
, respectively. And capitulum had antimicrobial activities against Bacillus subtilis, Staphylococcus aureus, Enterobacter aerogenes, Citrobacter freundii, Vibrio vulnificus, Pseudomonas aeruginosa, Saccharomyces cerevisiae. By the way, leaf and stem rarely had antimicrobial activity. Antimicrobial activities of capitulum according to harvesting date were very various. Capitulum on August 30 had the highest antimicrobial activities against Bacillus subtilis, Staphylococcus aureus, Vibrio vulnificus, Saccharomyces cerevisiae and on July 30 against Enterobacter aerogenes, Citrobacter freundii, Pseudomonas aeruginosa.

This experiment was conducted to investigate the optimum nitrogen fertilization conditions for the production of high-quality Rhodiola rosea L. in forcing culture. Up until 48 kg N/10 a of both urea and ammonium sulfate, dry matter yield of root of Rhodiola rosea L. tended to increase with increase in application rates, however, it decreased thereafter in higher application rates. In the case of urea, the content of salidroside in the root of the Rhodiola rosea L. appeared to decrease rapidly from the application rates of 64 kg N/10 a and over. Meanwhile, the content of salidroside in the root tended to decrease gradually with the application rates exceeding 64 kg N/10 a of ammonium sulfate. The optimum fertilization rates of urea and ammonium sulfate was 45-8-20-10-10 (N-P-K-Ca-Mg) kg/10 a according to the curvilinear regression equation. However, considering the nitrogen accumulation in soil, nitrogen translocation into the plant, and dry matter yield and content of salidroside in the root of Rhodiola rosea L., the optimum fertilization rates of urea and ammonium sulfate would be 40-8-20-10-10 kg/10 a and 35-8-20-10-10 kg/10 a, respectively.
