In an attempt to evaluate licorice quality based on its biological activity, we grafted an on-line high-performance liquid chromatography (HPLC) bioassay method into the previously established HPLC analysis method. The common antioxidant peaks in licorices of various origin were observed through an on-line HPLC/DPPH system leading to a decrease in absorbance at 517 nm for 2,2-diphenyl-1-picrylhydrazyl (DPPH). Among them, the licorice from Youngju possessed the highest activity. Therefore, three active standard compounds from the dehydroglyasperin C, dehydroglyasperin D, and isoangustone A, were isolated and elucidated by medium pressure liquid chromatography (MPLC) and instrumental analysis such as nuclear magnetic resonance (NMR), respectively. On-line HPLC/ABTS analysis method with the simultaneous determination of three standard compounds and their radical scavenging activity was established for the quality evaluation of licorices. 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radicals (ABTS) which is stable and effective was used in replace of DPPH. The radical scavenging activity of three standards is compared with that of Trolox, known as antioxidant, showing a negative peak with a decrease in absorbance at 734 nm for ABTS. This on-line HPLC/ABTS analysis method was validated for specificity, linearity, precision and accuracy in compliance with international conference on harmonization (ICH) guideline.

Toxoplasmosis is an important cause of foodborne, inflammatory illnesses, as well as congenital abnormalities. Currently available therapies are ineffective for persistent chronic disease and congenital toxoplasmosis or have severe side effects which may result in life-threatening complications. There is an urgent need for safe and effective therapies to eliminate or treat this cosmopolitan infectious disease. The aim of this study was to investigate the in vitro anti-Toxoplasma activities of Suaeda maritime, one of the halophytes, using tachyzoit of T. gondii RH strain infected HeLa cells. As the results, the selectivity of Suaeda maritime extract was 6.63, which was higher than Sulfadiazine selectivity (2.06). Also, we perfomed the cell proliferation inhibition test and the morphological study to evaluate the anti-T. gondii activity of Suaeda maritime extract with HeLa cells. As the results, the inhibition rate of the Suaeda maritime extract was high inhibition rate. This indicates that the Suaeda maritime extract may be used for new anti-T. gondii agent.

In general, Reucedani Radix (Peucedanum japonicum Thunbergis: PJ) is the Korean traditional herbal medicine used to remove dampness, to relieve pain, and spasm. So, PJ folium is believed to have the same effects. The aim of this study is to investigate the alleviation of dextran sulfate sodium (DSS) induced ulcerative colitis in mice by PJ folium. 25 mice were divided into 5 groups: normal, DSS, DSS + 100 mg/kg PJ folium (PJ100), DSS + 500 mg/kg PJ folium (PJ500), and DSS + 150 mg/kg 5-amino salicylic acid (5-ASA) groups. Body weights, colon lengths, histological changes in colon tissue, and spleen weights were observed. Inflammatory cytokines such as IL-
, IL-6, and TNF-
level in plasma were measured by ELISA. IL-
, IL-6, and TNF-a mRNA expression in colon tissue were detected by RT-PCR. In the results, body weight lose was inhibited in PJ100, PJ500, and 5-ASA groups, but it was not different compared with DSS group, significantly. PJ500 group showed the preventive effects of colon length shorten and histological changes in colon tissues as good as 5-ASA group. The weight of spleen was increased in DSS group but it reduced in PJ100, PJ500, and 5-ASA groups. Moreover, IL-
cytokine levels in plasma were reduced in PJ500 and 5-ASA groups. IL-
, IL-6, and TNF-a mRNA expression in colon tissue were inhibited in PJ100, PJ500, and 5-ASA groups and it was significantly different compared with DSS group. In conclusion, PJ folium showed the alleviative effect on DSS induced ulcerative colitis in mice.

DOI : 10.7732/kjpr.2014.27.5.429
This study was designed to investigate the effects on anti-oxidative activities and increasing extraction yield of Aralia elata Cortex by gamma irradiation. Electron spin resonance (ESR) analysis as physical techniques for irradiation identification of Aralia elata showed that a pair of peak appeared on a space of 6.0 mT at the left and right of symmetric unspecific central ESR spectrums, confirming that the plant was gamma-irradiated. The optimum extracting conditions for preparing gamma irradiated samples from Aralia elata Cortex were to extract with 50% ethanol for 15 hrs after 10 kGy irradiation. DPPH scavenging activity and ABTS radical cation inhibitory activity of the water and 50% ethanol extracts from non irradiated and irradiated Aralia elata Cortex was very high as over 80% and 98%, respectively, at tested low concentration of
. Antioxidant protection factor (PF) as anti-oxidation indicator of lipophilic compounds showed a very high level of activity as 2.18~2.78 PF. As for TBARs, water and ethanol extracts showed high level. Increase of TBARs inhibitory activity of water extracts was not shown by gamma-ray irradiation but ethanol extracts showed slight increasement of TBARs inhibitory activity with 10 kGy gamma-ray irradiation. These results shown confirmed increasement of extraction yield for phenolic compounds and anti-oxidative activity from Aralia elata. Thus, the treatment of gamma-irradiation can be used a way to amplify a solubility for biological active compounds and anti-oxidative activity in plants.

This study describes a preliminary evaluation of the anti-inflammatory activity of Castanopsis cuspidata extracts. C. cuspidata was extracted using 80% ethanol and then fractionated sequentially with n-hexane, dichloromethane, ethylacetate, and butanol. To screen for anti-inflammatory agents effectively, we first examined the inhibitory effect of the C. cuspidata extracts on the production of pro-inflammatory factors and cytokines stimulated with lipopolysaccharide. In addition, we examined the inhibitory effect of C. cuspidata extracts on pro-inflammatory mediators (NO, iNOS, COX-2) in murine macrophage RAW 264.7 cells. The amounts of protein levels were determined by immunoblotting. Of the sequential solvent fractions of C. cuspidata, the n-hexane, dichloromethane and ethylacetate fractions inhibited the mRNA expression of pro-inflammatory cytokines (IL-
and IL-6), production of NO, and the protein level of iNOS and COX-2. These results suggest that C. cuspidata may have significant effects on inflammatory factors and may be provided as a possible anti-inflammatory therapeutic plant.

The Polygonatum odoratum cv. Gungangbeaksea, bred in Gyeongsangnam-Do Agricutural Research & Extension Service, was cultured in vitro for micropropagate rapidly through the culture of rhizome explants (
explants of adventitious multi-bud clusters (AMC), obtained through the culture of rhizome explants (MS + 3.0 mg/L BA) were cultured on MS media with BA and TDZ. The shoot multiplication was favorable on the MS medium containing 3.0 mg/L TDZ with 2.8 in shoot number. But the formation of AMC was low in all media tested. The explants of AMC were cultured on MS media containing 1.0~5.0 mg/L TDZ and NAA to multiplicate AMC more. The formation of AMC was a little more stimulated on combined MS media of TDZ and NAA, than that with TDZ alone. The multiplication of shoots and AMC was favorable on MS media with 3.0 mg/L TDZ and 5.0 mg/L NAA, and 5.0 mg/L TDZ and 3.0 mg/L NAA. As the concentration of MS salts increased, the formation of AMC was decreased. But the formation of AMC was more stimulated, as the concentration of sucrose increased to 7%. Therefore, the multiplication of shoots and AMC was suitable on media containing 3.0~5.0 mg/L TDZ and NAA, and 7% of sucrose. The explants of AMC were rooted on media with 3.0 mg/L IBA, or 2.0 mg/L NAA with more than 80% in rooting ratio. The plantlets were treated at
for 8 weeks, and cultured ex vitro for 8 weeks. The survival ratio of plantlets were 100% in vermiculite, and the mixed soil with perlite 1 volumn and vermiculite 1 volumn.

DOI : 10.7732/kjpr.2014.27.5.546
The final aim of this study is to develop a biofiltration system integrated with plant vegetation for improving indoor air quality effectively depending on indoor space and characteristics. However, to approach this final goal, several requirements such as constant pressure drops (PDs) and soil moisture contents (SMCs), which influence the capacity design for a proper ventilation rate of biofiltration system, should be satisfied. Thus, this fundamental experiment was carried out to adjust a proper wind speed and to ensure a stabilization of initial SMCs within biofilter for uniform distribution of SMCs and PDs, and for normal plant growth, especially avoiding root stress by wind. Therefore, we designed horizontal biofliter models and manufactured them, and then calculated the ventilation rate, air residence time, and air-liquid ration based on the biofilter depending on three levels of wind speed (1, 2, and
). The relative humidity (RH) and PD of the humidified air coming out through the soil within the biofilter, and SMC of the soil and plant growth parameters of lettuce and duffy fern grown within biofilter were measured depending on the three levels of wind speed. As a result of wind speed test,
was suitable to keep up a proper RH, SMC, and plant growth. Thus, the next experiment was set up to be two levels of initial SMCs (low and high initial SMC, 18.5 and 28.7%) within each biofilter operated and a non-biofiltered control (initial SMC, 29.7%) on the same wind speed (
), and measured on the RH and PD of the air coming out through the soil within the biofilter, and SMC of the soil and plant growth parameters of Humata tyermani grown within biofilter. This result was similar to the first results on RHs, SMCs, and PDs keeping up with constant levels, and three SMCs did not show any significant difference on plant growth parameters. However, two biofiltered SMCs enhanced dry weights of the plants slightly than non-biofiltered SMC. Thus, the stability of this biofiler system keeping up major physical factors (SMC and PD) deserved to be adopted for designing an advanced integrated biofilter model in the near future.

In this study, we collected 29 Kenaf (Hibiscus cannabinus L.) genetic resources from 10 countries to confirm the possibility of the introduction into Korea. The Kenaf (Hibiscus cannabinus L.) has the broad industrial use like feed and the 5 times more strong
absorption capacity compared to general plant. So recently it is considered as a good industrial source. We analyzed ecotype, growth and development, yield and feed value of collected resources. They were divided into 3 groups depending on flowering time, early maturing type blooming in early July, mid-late maturing type blooming from end of August to early September and late maturing type blooming in end of October. Early maturing type could get fruitful seed but dropped yield (average 7,895 kg/10a) and late maturing type could get high yield (average 12,572 kg/10a) but deletion. The other side mid-late maturing type could get yield over a certain level (average 11,207 kg/10a) and fruitful seed was ensured. The yields analyzed by resources indicated that K12 (Hongma 300) collected in China, K25 from India, K22 from Russia and K21 (Khonkaen 60) variety from China were more than 13,500 kg per 10a. Feed value of early maturing type had inclined to more better than other types, but like dry digestible matter (DDM) and dry matter intake (DMI) of some late maturing types like K12, K21, K22 which had a high yielding ability were more better than that of early maturing types'. So relative feed value (RFV) which considered comprehensive item for feed value were indicated K21 was 102.5, K12 was 116.2 and K22 was 120.2. 'Jangdae' the variety developed in Korea which could complement of other types' had a good quality for yield 10,975 kg/10a and 12.5% crude protein content and 101.9 of the relative feed value. So we need to be taken power to collection of mid-late maturing types resources.

Resveratrol is a naturally occurring stilbene which is safe and well-described compound with a potent anti-inflammatory activity. Recent studies suggested that resveratrol suppressed various inflammation mediated diseases such as asthma, chronic colitis, rheumatoid arthritis, and type 1 diabetes. These studies indicated that resveratrol might directly modulate
helper T cells (Th cells)-mediated immune responses. However, it is not fully elucidated whether resveratrol directly regulates
Th cell activation and differentiation. In the present study,
Th cells were purified from C57BL/6 and treated with various concentrations of resveratrol. We found that resveratrol directly suppressed
Th cells activation, leading to a defect in T cell proliferation. When
Th cells were treated with resveratrol, cytokine production was also significantly reduced in a dose dependent manner. In accordance with these results, resveratrol even inhibited
Th cells differentiation into Th1, Th2 or Th17, which produces IFN-
, IL-4 or IL-17 respectively. We also found that resveratrol could induce apoptosis of
T cells at a high concentration. Our data demonstrated that resveratrol inhibited directly
Th cells activation and differentiation. It suggests that resveratrol could be an efficient therapeutic strategy for autoimmune diseases in which
Th cells play a critical role.

The purpose of this research is to classify various plants written in the Korean Buddhist scriptures and assign scientific name to them in accordance with the Hangul Tripitaca as standard scriptures, thereby establishing the foundation of the plants in Buddhist scriptures. As a natural resource, we also assessed the value of the plants written in the Buddhist scriptures that distributed from other countries. To this end, we inferred the route of introduction to Korea of the plants and investigated their function and usage. Taxonomic classification of the plants written in Buddhist scriptures identified a total of 331 taxa belonging to 107 families, 244 genera, 313 species, 1 subspecies, 16 varieties, 1 forms. Species composition of the 331 taxa of plants consisted of two taxa of pteridophyte, 15 taxa of gymnosperm, 261 taxa of dicotyledon, and 53 taxa of monocotyledon. Among them, 183 and 148 were woody and herbaceous plants, respectively. Analysis of the distribution of 331 kinds of plants that India's portion of origin of place is 8.9% which holds a low rank compared with those of Korea (10.5%), China (10.9%), and Japan (10.0%). This explains why many taxa of plants distributed from the three countries appeared in the Hangul Tripitaca. Accordingly, we hypothesized that the majority of the plants were added and replaced at some point in past while Buddhist scriptures were propagated from India to China and from China to Korea. Our analysis indicated that 119 out of the 331 taxa (36 %) were distributed from Korea.
