To make the soil moisture proper is the important factor in the seedbed cultivation of Yangjik for producing a good quality of ginseng seedling. This study was carries out to investigate the effect of soil moisture on photosynthesis and yield of ginseng seedling under the different condition of the soil moisture, such as
mbar. Photosynthesis rate was decreased gradually by the reduction of soil moisture, and in particular it was decreased distinctly under the lower condition of soil moisture, such as
mbar. Photosynthesis rate in air temperature of
was decreased more distinct than that of
, Light saturation point of leaves was at the quantum of
while it was decreased by
according to the increase of air temperature. Respiration rate was increased by the increase of quantum, and decreased by the reduction of soil moisture. Respiration rate under the condition of high quantum was increased regardless of air temperature, but it was decreased distinctly under the condition of low soil moisture and high air temperature, such as 400 mbar at
. There were a gradual decrease by the reduction of soil moisture in leaf length, leaf width, chlorophyll content, and water content of leaves, but heat injury ratio was increased distinctly by the reduction of it. Total root weight, root weight per plant, the yield of usable seedling were decreased by the reduction of soil moisture, and optimal content of soil moisture to produce a good quality of seedling was 63% of field capacity or 18.9% in absolute soil moisture content.

Arthropod pests were surveyed from 132 herb species of 121 genera in 50 families of 32 orders at herb garden of Sancheong-gun Agricultural Development Technology Center in Sancheong, Gyeongsangnamdo province from October, 2005 to November, 2006. Ninety eight arthropod pests of 86 genera in 44 families of 9 orders were collected. Although less than 5 arthropod pests were collected from each herb, more than 5 arthropod pests were occurred on Hibiscus mutabililis, Peucedanum japonicum, Aralia cordata, Fraxinus rhynchophylla, Angelica decursiva, Rhaponticum uniflorum, Lonicera japonica, Betula platyphylla and Agrimonia pilosa. Out of collected pests, 98.5% of them damaged leaves of medicinal plants. The highest number of arthropod pests was recorded in May representing 36 species of 32 genera in 20 families of 6 orders. Most of them were collected from less than 5 medicinal plants. However, Atractomorpha lata, Dolycoris baccarum, Myzus persicae, and Nysius plebejus occurred on 42., 22, 20, and 15 medicinal plants, respectively. Atractomorpha lata and Myzus persicae had broad host ranges and seriously damaged. Aphis gossypii was dominant insect pest in May compared with Dolycoris baccarum in June. Atractomorpha lata in August and September, and Myzus persicae in October.

To develop new high valuable Gugija (Lycium chinensis), biofunctionalities of Gugija standard species and its hybrids were investigated and compared with each water extracts and methanol extracts from Lycii Fructus, Lycii Folium and buds and Lycii Cortex Radicis. Among various biofunctionalities of Gugija standard species, antioxidant activity was showed the highest in methanol extracts from buds of Cheongwoon species (93%) and antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity was 84.1% in the water extracts from Lycii Cortex Radicis of Cheongyang NO.7. Futhermore, methanol extracts from Lycii Cortex Radicis of Myungan A-2 hybrid showed 93.1% of antioxidant activity and 96.9% of ACE inhibitory activity was also showed in the methanol extracts from Lycii Fructus of DO148-72(A11) hybrid. However, fibrinolytic activity and anticholesteromia HMG-CoA reductase inhibitory activity were weak or not detected in almost of Gugija standard species and its hybrids. Therefore, we finally selected Cheongwoon Gugija standard species (buds) and Myungan A-2 hybrid (Lycii Cortex Radicis) as good antioxidant sources and also DO148-72 (A11) hybrid (Lycii Fructus) as excellent antihypertensive ACE inhibitior sources for manufacturing functional food product.

This study was performed to investigate the reduction of toxicity and improvement of anticancer activities from R. sachalinensis by ultra high pressure extracts process. The cytotoxicity on human kidney cell (HEK293) and human lung cell (HEL299) was showed below 20.4% and 21.6% as compare to normal extracts in adding 1.0
concentration. This showed that toxic materials through ultra high pressure processing is broken or degraded. Because bond such as hydrogen bond, electrostatic bond, Van der waals bond, the hydrophobic bond, can be broken by high pressure. The anticancer activity was also increased in over 7% by high pressure processing in A549, AGS, MCF-7 and Hep3B cells. The result showed that extraction by high pressure have low cytotoxicity and high anticancer activity. So, the high pressure extraction technology can play an important role in eruption of new material with high biological activity.

Jo, Hyeong-Chan ;
Korean Journal of Medicinal Crop Science, volume 15, issue 6, 2007, Pages 417~428
Most oriental medicinal plants in domestic markets have been imported, but these medicines are being easily exposed to many insect pests because of the poorness of storage facilities. This study was carried out to identify stored products insect pests occurring in 158 storage medicinal plants belonging to 134 genera of 67 families. No insect pests were not observed in 44 medicinal plants including Artemisia argyi Levl. et Vant., Cassia sieboldii Presl., and Juniperus chinensis L. Most commonly observed stored products insect pests in the surveyed medicinal plants were the order of as follows; Ahasverus advena(Waltl) 12.3%, Lasioderma serricorne F. 11.5%, Oryzaephilus surinamensis L. 10.3%, Tribolium castaneum (Herbst) 9.4%, Stegobium paniceum L. 8.4%, and Plodia interpunctella(Hbner) 7.9%. And these insects also are likely to prefer more root or rhizome part than the other ones. Based on these basic survey results, natural products researchers can obtain an important information in finding an insecticidal or fumigant compounds contained in the medicinal plants which any insect pests do not attack.

Shoot weight of Orostachys japonicus should determine its profitability. The study was carried out to measure the effect of nitrogen (N) fertilization level (0, 5, 10, 20kg/10a) on its growth, morphological characters, and flowering. Night-break treatment of 2 hours at midnight were done since Aug. 25 when afterward samples were taken every 4 weeks to Nov. 16. Growth, morphological and flowering related characters were measured from each sample. Plant height, inflorescence length, number of leaves including bracts and stem diameter were decreased with increased N levels. Leaf and bract, floret, shoot and total dry weights as well as withering rate showed similar response to the above morphological characters. Florets were less formed with increased N levels but were not flowered due to the night-break treatment, meaning that N fertilization had little effect on its growth and anthesis of the florets.

In the previous study, we reported the inhibitory effects of Rodgersia podophylla root extract on tyrosinase activity and melanin production in melan-a cells. However, mechanism of the inhibitory activity and in vivo assay were not yet examined. This study performed the examination of the effects of Rodgersia podophylla root extract on protein expression and in vivo depigmenting activity using melan-a cells and brown guinea pigs. As the results of western immunoblotting analysis, treatment of Rodgersia podophylla root extract reduced tyrosinase expression rates in 10 and 100 ppm concentrations, dose dependently. Moreover, Rodgersia podophylla root extract exhibited depigmenting activity on UV-B induced hyperpigmentation in brown guinea pig skin. These results suggested that Rodgersia podophylla root extract could act as whitening agent for the skin via not only direct tyrosinase activity inhibition but also reducing of tyrosinase expression.

This study was carried out to investigate the effect of dietary supplementation with red ginseng water-extracts on the induction of microsomal cytochrome P-450 in rats. Phenobarbital (PB) and 3-methylcholanthrene (3-MC), P-450 inducers, were administered to 3- or 12-month old rats received red ginseng extracts (25 mg/kg) from 6 weeks to 12 months for 3 days. PB and 3-MC increased levels of P-450, P-450 reductase, ethoxycoumarin O-deethylase, benzphetamine N-demethylase and glutathione-S-transferase in the liver of rats. However, chronic administration of red ginseng significantly reduced these increase of enzyme levels induced by P-450 inducers. Chronic administration of red ginseng did not affect the induction of cytochrome
and NADH cytochrome
reductase by P-450 inducers. It is suggested that the induction of cytochrome P-450 system in the liver in relation to xenobiotics toxicity can be modulated by long-term supplementation with Korean red ginseng to rats.

Lee, Yong-Gyu ; Cho, Jae-Youl ;
Korean Journal of Medicinal Crop Science, volume 15, issue 6, 2007, Pages 451~456
Curcumin, a polyphenolic antioxidant purified from turmeric, has been known to possess various biological activities such as anti-oxidative, anti-inflammatory and anti-cancer effects. In this study, we have explored anti-inflammatory effect of curcumin using Gram (-) bacterium-derived endotoxin (lipopolysaccharide: LPS) and macrophage cell line RAW264.7. Curcumin suppressed NO production in LPS-activated RAW264.7 cells in a dose-dependent manner, Curcumin also blocked the activation of
but not AP-1 according to luciferase assay. Furthermore, this compound suppressed the phosphorylation of a series of intracellular signaling components such as Src, JAK-2, Akt, IKK and
under LPS stimulation in a time dependent manner, Therefore, our data suggest that curcumin was able to protect the host from Gram(-) bacterial-infection-mediated inflammatory symptoms.
