The leaves (KPL) of Kalopanax pictus (KP) are used as a vegetable or a functional food in Korean society. The stem bark (Kalopanacis Cortex, KPS) has been traditionally used to treat neurotic pain, rheumatoid arthritis and diabetic disease. This research was undertaken to demonstrate that the leaf extract of KP (KPL) has also the antinociceptive and antiinflammatory effects like the extract (KPS) of Kalopanacis Cortex and to compare the activity levels of several extracts obtained from KP. Antinociceptive and antiinflammatory effects were measured against the extracts described as followings; KPL-1 (the MeOH extract obtained from the leaf shoot of KP collected on May), KPL-2 (the MeOH extract from KP collected on June), KPL-3 (the MeOH ectract from KP with no thorns), KPS-1 (MeOH extract from KPS of a Korean habitat), KPS-2 (MeOH extract from KPS of a Chinese habitat). The antimociceptive test undertaken by acetic acid-induced writhing, hot plate-, and tail-flick methods using mice. The anti-inflammatory test was also undertaken by measuring the edema in the carrageenan-induced test. The order of activity potency in the antinociceptive and antiinflammatory assays was commonly shown as followings: KPL-3>KPS>1>KPS-2>KPL-1>KPL-2. This order was also observed in acetic acid-induced vascular permeability test. The antiinflammatory activity in carrageenan-induced assay was also observed as the following order: KPL-3>KPS- 1>PS-2>KPL-1>KPL-2. In addition, adjuvant-induced rats were used for a model to assess the oxidative stress. Treatment of the rat with the extracts reduced serum thiobarbituric acid-reactive substances (TBARS), hydroxy radical(OH) and superoxide dismutase(SOD) activity caused by FCA together together with the inhibition of hepatic TBARS level and lipofuscin content. The above finding suggests that the leaf extract has the antinociceptive and antinflammatory activity. It is also suggested that KPL-3 with more potent activity than other tested extracts could be developed for a new available biomaterial.

This research was carried out to elucidate the characteristics of stomatal transpiration, water efficiency, vapor pressure deficit of leaves by the light intensity Kalopanax pictus leaves. The results obtained are summarized as follows: 1. In the upper leaves of Kalopanax pictus seedlings, the stomatal transpiration rate increased continuously with increasing light intensity, but in the middle and lower leaves. it was saturated at $100{\mu}mol\;m^{-2}S^{-1}$. At the light saturated point. the stomatal transpiration rate was in the following order: the upper ($1.29mmol\;H_2O\;m^{-2}S^{-1}$) middle ($0.56mmol\;H_2O\;m^{-2}S^{-1}$) lower leaves ($0.31mmol\;H_2O\;m^{-2}S^{-1}$). 2. In the upper leaves, water use efficiency rapidly increased to $600{\mu}mol\;m^{-2}S^{-1}$, and then decreased. In the middle and lower leaves, it increased to $400{\mu}mmol\;m^{-2}S^{-1}$, and then showed a constant values. 3. The vapor pressure deficit (VPD) in according to leaf positions was linearly decreased with increasing photosynthetic photon flux density (PPFD).

In order to develop new Kalopanax pictus shoot Jangajji (KJ) with low salt concentration, physicochemical changes of KJ soaked at different concentration of soybean sauce (10~50%) were investigated for 50 days. The pH of KJ increased significantly with increasing concentration of soybean sauce in soaking solution (P<0.05). Titratable acidity and NaCl concentration of all KJ increased during storage for 50 days at $10^{\circ}C$. The total bacterial count slowly increased during early storage time and reached its highest level (4.74 log CFU/g) after storage for 30 days. KJ-20 (KJ added with 20% soy sauce) showed the highest scores for taste, flavor, texture, and overall acceptability. The total polyphenol and flavonoid contents of KJ extract increased with increasing concentration of soybean sauce. DPPH and ABTS radical scavenging activities of KJ extract were 27.22% and 38.37% (control), 40.74% and 43.65% (KJ-10), 41.79% and 50.37% (KJ-20), 43.09% and 52.60% (KJ-30), 48.62% and 53.45% (KJ-40), and 50.85% and 60.79% (KJ-50), respectively.

In this study, we examined the antimicroboal effect against Actinobacillus actinomycetemcomitans and Prevotella intermedia which were the bacteria causing the Periodontopathic by using 34 types of natural plant extracts. Therefore, this study measures growth inhibition activity and Minimum Inhibition Concentration (MIC) of a sample extract with the use of organic solvent extracts in order to analyze the antibacterial effect of natural plant extracts on periodontopathic bacteria. Each of the 34 types of natural plant extracts were extracted by using the ethanol, and subsequently, the size of growth inhibition zone(clear zone, ㎜) of respective extracts were measured through the disk diffusion method. As a result, it was found that the growth inhibitory activity was found for A. actinomycetemcomitans, which is the bacteria causing the Periodontitis, in 13 types of natural plant extracts such as Raphanus sativus, Akebia quinata, Paeonia lactiflora, Belamcanda chinensis, Inula britannics, Houttuynia cordata, Forsythia saxatilis, Gentiana macrophylla, Melia azedarach, Scutellaria baicalensis, Coptis chinensis, Phellodendron amurense, Kalopanax Pictus, etc. In the case of P. intermedia, the growth inhibitory activity was found in 13 types of natural plant extracts such as Raphanus sativus, Angelica acutiloba, Akebia quinata, Belamcanda chinensis, Inula britannics, Houttuynia cordata, Cinnamomum cassia, Aster tataricus, Melia azedarach, Scutellaria baicalensis, Coptis chinensis, Phellodendron amurense, Kalopanax Pictus etc. For A. actinomycetemcomitans, anti-bacterial effect was exhibited in Belamcanda chinensis, Cinnamomum cassia, Kalopanax Pictus, Phellodendron amurense, Coptis chinensis. The Coptis chinensis showed the most excellent growth inhibitory activity in all organic solvent fragment, while P. intermedia showed the growth inhibitory activity in Belamcanda chinensis, Cinnamomum cassia, Meliaazedarach, Phellodendron amurense, and Coptis chinensis.

In this study, we investigated the inhibitory activities on gastritis and gastric ulcer using liriodendrin which is a constituent isolated from Kalopanax pictus. To elucidate its abilities to prevent gastric injury, we measured the quantity of prostaglandin $E_2$ ($PGE_2$) as the protective factor, and we assessed inhibition of activities related to excessive gastric acid be notorious for aggressive factor and inhibition of Helicobacter pylori (H. pylori) colonization known as a cause of chronic gastritis, gastric ulcer, and gastric cancer. Liriodendrin exhibited higher $PGE_2$ level than rebamipide used as a positive control group at the dose of $500{\mu}M$. It was also exhibited acid-neutralizing capacity (10.3%) and $H^+/K^+$-ATPase inhibition of 42.6% ($500{\mu}M$). In pylorus-ligated rats, liriodendrin showed lower volume of gastric juice ($4.38{\pm}2.14ml$), slightly higher pH ($1.53{\pm}0.41$), and smaller total acid output ($0.47{\pm}0.3mEq/4hrs$) than the control group. Furthermore liriodendrin inhibited colonization of H. pylori effectively. In vivo test, liriodendrin significantly inhibited both of HCl/EtOH-induced gastritis (46.9 %) and indomethacin-induced gastric ulcer (46.1%). From these results, we suggest that liriodendrin could be utilized for the treatment and/or protection of gastritis and gastric ulcer.

The stem-bark of Kalopanax pictus (KP, family Araliaceae), of which main constituent is kalopanaxsaponin B, has been used for asthma, rhinitis, and arthritis in Chinese traditional medicine. To clarify anticolitic effect of KP, we examined anti-inflammatory effect of KP extract and kalopanaxsaponin B in lipopolysaccharide (LPS)-stimulated peritoneal macrophage and 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitic mice. Of KP extracts, KP BuOH-soluble fraction most potently inhibited LPS-induced IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ expression, as well as NF-${\kappa}B$ activation. However, KP BuOH fraction increased IL-10, an anti-inflammatory cytokine. KP BuOH fraction also inhibited colon shortening and myeloperoxidase activity in TNBS-induced colitic mice. KP BuOH fraction also potently inhibited the expression of the pro-inflammatory cytokines, IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ as well as the activation of NF-${\kappa}B$. Kalopanaxsaponin B, a main constituent of KP, inhibited TNBS-induced colonic inflammation, including colon shortening, and TNBS-increased myeloperoxidase activity pro-inflammatory cytokine expression and NF-${\kappa}B$ activation in mice. Based on these findings, KP, particularly its main constituent, kalopanaxsaponin B, may ameliorate colitis by inhibiting NF-${\kappa}B$ pathway.

In this study, the antioxidant activity of water and ethanol extracts from Hibiscus esculentus, Cirsium japonicum, Zizania latifolia and Kalopanax pictus for functional food source were examined. The optimal conditions for phenolic compounds extraction from medicinal plants were at 50% ethanol with Hibiscus esculentus and Cirsium japonicum var. ussuriense, at 40% ethanol with Kalopanax pictus and at 60% ethanol with Zizania latifolia. The total phenolic contents from the extracts of medical plants were determined to be 2.72~34.15 mg/g in the water extracts and 2.83~34.23 mg/g in the ethanol extracts. The electron-donating abilities (EDA) of the water and ethanol extracts were both above 74% at the low concentration of $50{\mu}g/mL$. The ABTS radical-cation decolorization was above 88% at $100{\mu}g/mL$ concentration in all the extracts of various medicinal plants. The antioxidant protection factor (PF) in the water and ethanol extracts of the Cirsium japonicum var. ussuriense extracts was $1.73{\pm}0.02PF$ and $1.76{\pm}0.01PF$ at $50{\mu}g/mL$ concentration respectively, and was higher than those of the other medicinal-plant extracts. The TBARs inhibition rates of all the medicinal-plant extracts, were above 80% at the $50{\mu}g/mL$ concentration except Hibiscus esculentus. These results confirmed that the various oriental medicinal plants (Hibiscus esculentus, Cirsium japonicum var. ussuriense, Kalopanax pictus and Zizania latifolia) that were included in this study are useful anti-oxidant and functional-food resources.

Vegetational data obtained from 50 quadrats of Mt. Jungwangsan area were analysed by applying two multivariate methods : two-way indicator species analysis(TWINSPAN) for classification and detrended canonical correspondence analysis(DCCA) for ordination. DCCA technique allowed to extract the ordination axes that could be related to 15 environmental factors. The forest vegetation in Mt. Jungwangsan was classified into Quercus mongolica-Tilia amurensis, Quercus mongolica-Rhododendron schlippenbachii, Quencus mongolica-Kalopanax pictus, Quercus mongolica-Carpinus cordata, Quercus mongolica-Cornus controversa, Betula costata, Fraxinus mandshurica, and Ulmus laciniata communities according to the TWINSPAN. The relationships between the distribution of dominant species of forest vegetation and soil condition in Mt. Jungwangsan were investigated by analyzing elevation and soil nutrition gradient. Ulmus laciniata, Betula costata, and Fraxinus mandshurica forest were distributed in a ravine of the low elevation and in the good nutrition area of $Mg^{{+}{+}}$, total nitrogen, and $Ca^{{+}{+}}$, Quercus mongolica groups in the high elevation and in the poor nutrition area. Quercus mongolica-Kalopanax pictus forest of Quercus mongolica groups was distributed in the high elevation and in the good nutrition area of $Ca^{{+}{+}}$, C.E.C., $Mg^{{+}{+}}$, and total nitrogen, Quercus mongolica-Rhododendron schlippenbachii forest in the low elevation and poor nutrition area. Quercus mongolica-Carpinus cordata forest and Quercus mongolica-Cornus controversa forest were distributed in the medium elevation and medium nutrition area. The two dominant factors influencing community distribution were elevation and topography.
