This study was presented to the physiological activities such as metal chelating capacity, superoxide dismutase-like activity, anti-inflammation, cytotoxicity from Zanthoxylum schnifolium fruit. The values for metal chelating capacity of 1 mg/mL of 70% EtOH and 70% MeOH extracts were 68% and 67%, respectively, it was shown that metal chelating capacity in a dose-dependent manner. The 100% EtOH and 100% MeOH extract exhibited strong superoxide dismutase-like activity. The highest SOD-like activity obtained from 100% EtOH was 51% at a concentration of 4 mg/mL. The all extracts of Zanthoxylum schnifolium fruit except $H_2O$ extract significantly decreased the concentration of LPS-induced NO in Raw 264.7 cells. The 100% EtOH, 100% MeOH and 70% EtOH extract represented the highest activity in the anti-inflammation properties in vitro. However, the 100% EtOH and 100% MeOH extracts has cytotoxicity in Raw 264.7 cells and it may affect cell viability. Conclude that 70% EtOH extract was most suitable for anti-inflammation. Our results revealed that the Zanthoxylum schnifolium fruit expected to physiological activities.

This study was performed to the activity of antioxidant and anti-diabetic from Zanthoxylum schnifolium fruit. The Zanthoxylum schnifolium fruits were extracted with water, 100% methanol, 100% ethanol, 70% methanol and 70% ethanol. The activities of each extracts were measured by antioxidant tests, such as total phenolic contents, total flavonoid contents, hydroxyl radical activity, DPPH radical scavenging activity, reducing power and $\alpha$-glucosidase inhibition activity assay. The water extract represented the highest activity in the antioxidants properties in vitro, including hydroxyl radical activity, DPPH radical scavenging activity, reducing power. Furthermore, water extract also showed significantly high total phenolic contents but the 100% methanol extract showed high total flavonoid contents estimated as $196.48{\mu}g/mg$. The $IC_{50}$ values for $\alpha$-glucosidase inhibition activity of the 100% ethanol and 100% methanol extracts were $275.66{\mu}g/mg$ and $261.44{\mu}g/mg$. Our results indicated that the Zanthoxylum schnifolium fruit expected to be useful as antioxidants.

This study was presented to the anti-cancer activity from different fraction of Zanthoxylum schnifolium fruits. The values for human colon cancer cell(HT-29) survival rate of 0.3 mg/mL of 70% EtOH and 70% MeOH ethyl acetate fraction extracts were 7.62${\pm}$0.173%, 7.66${\pm}$0.037%, respectively. It was shown that human colon cancer cell(HT-29) survival rate was in a dose-dependent manner. The percentages of cells were increased in the sub-G0 and G0/G1 phase region, meaning that cell proliferation was decreased. The RT-PCR demonstrated that 70% EtOH and 70% MeOH ethyl acetate fraction extracts were down-regulated the expression of Bcl-2 and survivin genes in HT-29 cells. We examined that 70% EtOH and 70% MeOH ethyl acetate fraction extracts anti-cancer activities initiated through ROS generation suggesting that HT-29 cells treated with ethyl acetate fraction extracts induced ROS generation. Our results revealed that the Zanthoxylum schnifolium fruit may expect for anti-cancer activities in HT-29 cells.

The aim of this study was to identify essential oils (EOs) and their concentrations that improved the sensory characteristics of Kochujang by analyzing the effect of the essential oil on the sensory characteristics of Kochujang. EOs from Chrysanthemum indicum, Chrysanthemum morifolium, Zanthoxylum piperitum and Zanthoxylum schnifolium, which have an outstanding flavor, were added to Kochujang and the resulting products were subjected to sensory evaluation as a function of storage period. The change in the color of Kochujang by the addition of these EOs from Chrysanthemum indicum, Chrysanthemum morifolium, Zanthoxylum piperitum and Zanthoxylum schnifolium was not observed. Kochujang's characteristic flavor was decreased by an increase in the concentrarion of EOs; however, no significant difference was observed when 0.0005% EOs were added relative to the none-additive groups (p<0.05). EOs addition did not affect the hot taste of Kochujang and as the additive quantity increased Kochujang's characteristic taste significantly decreased (p<0.05). After a storage period of 12 weeks, the overall preference of Chrysanthemum indicum, Chrysanthemum morifolium, and Zanthoxylum piperitum was same as the none-additive groups (p<0.05). Therefore, it is suggested that EOs from Chrysanthemum indicum, Chrysanthemum morifolium, and Zanthoxylum piperitum can be applied as additives to improve the characteristic taste and flavor of Kochujang and the recommended concentration level is 0.0005%.

This experiment was carrie out to investigate the amount of essential of leaves and fruits of Magnolia sieboldii, Magnolia hypoleuca, Evodia danillii male and female, Phellodendron amurense male and female and Zanthoxylum schinifolium male and emale by Karlsrube set on August, August, September and October in 1994. Essential oil yield was highest in the fruits of Zanthoxylum schinifollium leaves on Augus the amount of essential oil of Magnolia sieboldii and Magnolia hypoleuca leaves was more than the one of Evodia danillii, Phellodendron amurense and Zanthoxylum schnifolium leaves. The amount of essential oil were not diferent between male and female leaves.

속리산국립공원 법주사지역의 삼림군집을 대상으로 TWINSPAN에 의한 classification 및 DCA의 ordination 기법을 이용하여 식물군집구조를 밝히고 천이계열을 추정하기 위하여 70개 조사구(1조사구당 500$m^2$)를 설치하였다. TWINSPAN에 의한 classification 분석에서 6개의 군집으로 분리되어 소나무 군집, 신갈나무-소나무 군집, 졸참나무-신갈나무 군집, 신갈나무 군집, 서어나무-졸참나무 군집, 졸참나무 군집으로 나뉘었고, 분리환경인자는 해발 고와 토양습도였다. 본 연구에서는 DCA기법이 TWINSPAN보다 효율성이 더 좋았다. 천이계열은 교목상층에서는 소나무, 팥배나무$\longrightarrow$졸참나무$\longrightarrow$서어나무와 소나무, 쇠물푸래나무$\longrightarrow$신갈나무이었고, 교목하층 및 관목층에서는 참싸리, 개옻나무. 산초나무$\longrightarrow$철쭉, 참개암나무, 생강나무, 함박꽃나무$\longrightarrow$참회나무로 추정되었다. 산화발생에 의해서 식물군집의 종다양성은 매우 감소하였고, 참나무류의 상대우점치는 증가하였다.
