Mineral and volatile flavor compounds of Pimpinella brochycarpa N., a perennial Korean medicinal plant of the Umbelliferae family, were analyzed by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and simultaneous steam distillation extract (SDE)-gas chromatography mass spectrometry (GC/MS), head space solid phase micro-extraction (HS-SPME)-GC/MS. Mineral contents of the stalks and leaves were compared and the flavor patterns of the fresh and the shady air-dried samples were obtained by the electronic nose (EN) with 6 metal oxide sensors. Principal component analysis (PCA) was carried out using the data obtained from EN. The 1st principal values of the fresh samples have + values and the shady air-dried have - values. The essential oil extracted from the fresh and the shady air-dried by SDE method contain 58 and 31 flavor compounds. When HS-SPME method with CAR/PDMS fiber and PDMS fiber were used, 34 and 21 flavor compounds. The principal volatile components of Pimpinella brachycarpa N. were ${\alpha}$-selinene, germacrene D, and myrcene.

This study was performed to investigate the effect of ethanol extract of Pimpinella brachycarpa(PBE) on chronically ethanol-induced hepatotoxicity in rat liver. Sprague-Dawley rats weighing 90-130 g were divided into 5 groups; normal group(NOR), ethanol(35%, 10 ml/kg) treated group(CON), PBE 200 mg/kg treated group(P1), PBE 200 mg/kg and ethanol treated group(P2), and PBE 400 mg/kg and ethanol treated group(P3). PBE was also fractionated by the following solvent: n-hexane, chloroform, ethylacetate and n-butanol. The antioxidative capacity of the n-hexane fraction was the highest among fractions and was similar to that of butylated hydroxytoluene(BHT). The body weight gain and feed intake of the rats were decreased by ethanol administration, but were gradually increased to the similar levels of the NOR group by administering PBE. The AST activity in serum elevated by ethanol was significantly decreased by administering the high dosage of PBE, but exerted no significant change on serum ALT activity. It was also observed that the hepatic activities of xanthine oxide(XO), catalase and glutathione peroxidase(GSH-Px) increased by ethanol were markedly decreased in the combined ethanol and PBE administered groups(P2 and P3), but not in the activity of superoxide dismutase(SOD) as compared with the CON group. The glutathione(GSH) contents were decreased by ethanol adminstration, however, increased after administering PBE. These results suggest that ethanol extract of Pimpinella brachycarpa has a possible positive effect on the liver function in hepatotoxicity-induced rats by ethanol administration.

This study was carried out to make the new products of color moot as a functional food by variation of the color and flavor through addition of gamgyul, Daccus Carota Var. Sativa, Vitis vinifera, soy sauce, and Pimpinella brachycarpa N., respectively. For all the products, the color was observed by Colorimeter and the sensory evaluation was performed to evaluate their effectiveness and usefulness. The A$_w$ (water activity) test of color mooks has performed to examine their water activity individually. The A$_w$ of color moot was higher than that of the white one. The characters of texture of color mook as a function of the amount of the color and the flavor added were measured by a texture analyzer (XT-RA, Texturometer). By the TPA test, the rainbow and orange color mook examined were high in the springiness.

Attempts were made to regenerate plants from petiole explane of Forest Pimpinella barchycarpa via repetitive somatic embryogenesis. Effective induction of somatic emb교ogenesis was achieved on both MS and modified $B_{5}\;(mB_{5})$ media containing BA + 2,4-D or BA + 2,4-D + NAA under light condition (16-h photoperiod/day) cultures. The explants exposed to the ligt produced numerous somatic embryos while those kept under the dark did not form any on the same medium. Somatic embryos at different developmental stages were observed to arise within a individual explants. Plantlets could be regenerated on $mB_{5}$ basal medium or $mB_{5}$ containing 0.1 mg/L NAA Secondary adventive embryos were formed on the surface of the somatic embryos. Therefore, repetitive somatic embryogenesis could be achieved by secondary embryogenesis. Although the treatment of 2,4-D or NAA alone was effective in callus formation and growth, but not in induction of somatic embryogenesis. Some explants, cultured on NAA-containing media in darkness, produced only adventive roots. The embryogenic potential was maintained for two years when subcultured to BA and 2,4-D containing media with 5 weeks inteval. Regenerated plantlets were maintained on $mB_{5}$ or MS basal media for 4 to 6 more weeks and transferred to soil of an artificial mixture for acclimation. Most plantlets (more than 97%) survived, and grew without any deformity.

This study was performed to investigate the effect of ethanol extract of Pimpinella brachycarpa (PB) on serum and liver lipid metabolism in rats. Male Sprague Dawley rats were administered 1% cholesterol and 0.25% sodium cholate to induce hypercholesterolemia. PB ethanol extract (200 mg/kg/day or 400 mg/kg/day) was also administered orally to rats with high cholesterol diet for 6 weeks. We divided 40 rats into five groups; normal diet group (NC), high cholesterol diet group (HC), normal diet and PB ethanol extract (200 mg/kg) administered group (NC-PB), high cholesterol diet and PB ethanol extract (200 mg/kg) administered group (HC-PBL), and high cholesterol diet and PB ethanol extract (400 mg/kg) administered group (HC-PBH). The growth rate and liver weight of the high cholesterol diet group was higher than those of the normal diet group, whereas those of the groups administered PB ethanol extract were gradually decreased. There was a signigicant increase in the activities of serum alanine aminotransferase (ALT), asparate aminotransferase (AST) and alkaline phosphatase (ALP) in the high cholesterol diet group. The administration of PB ethanol extract decreased serum ALT, AST and ALP activities in a dose-dependent manners. The high cholesterol diet group showed increased serum triglyceride, total cholesterol, free cholesterol and LDL-cholesterol levels, and decreased atherogenic index, HDL-cholesterol and phospholipid levels as compared with the normal diet group. PB ethanol extract administrated groups showed increased HDL-C/T-C, HDL-cholesterol and phospholipid levels, and decreased serum triglyceride, total cholesterol, free cholesterol, and LDL-cholesterol levels as compared with the high cholesterol diet group. There were no differences in the concentrations of serum triglyceride, phopholipid, LDL-cholesterol, HDL-cholesterol and free cholesterol between normal diet groups. The hepatic concentrations of total cholesterol and triglyceride were also lower in PB ethanol extract administrated groups than in the high cholesterol diet group. These results suggest that ethanol extract of PB exerts hypocholesterolemic effect by reducing serum and liver cholesterol contents.

The aim of this study was to characterize the forest vegetation and site of Tongdaesan(Odaesan National Park) for ecological forest management. The deciduous forests of Tongdaesan are the result of cool, temperate climate. Direction and slope morphology contribute to differences in species composition and vegetaion structure. Based on the BRAUN-BLANQUET-approach, 242 releves were recorded and subsequently classified. The vegetation could be divided into two forest community groups, seven forest communities, and several groups. South exposed, dry slopes were covered with forests of the Quercus mongolica-Acer pseudo-sieboldianum community group. Differential species included grasses and sedges, e.g., Calamagrostis langsdorfii, Carex humilis and C. lanceolata. Quercus mongolica-Acer pseudo-sieboldianum community group could be subdivided into Rhododendron mucronulatum var. ciliatum community, Lespedeza${\times}$tomentella community, Carex humilis-Maackia amurensis community, Quercus mongolica-Acer pseudosieboldianum typical community and Pimpinella brachycarpa community. Carex humilis-Maackia amurensis community was divided into Galium kinuta subcommunity and typical subcommunity. Pimpinella brachycarpa community was divided into Vicia venosa var. cuspidata subcommunity and typical subcommunity. On north exposed, more humid and moist sites, forests of the Dryopteris crassirhizoma-Cornus controversa community group were found. This group was subdivided into Acer tschonoskii var. rubripes-Acer tegmentosum community and Deutzia glabrata-Ulmus laciniata community. Deutzia glabrata-Ulmus laciniata community was divided into Acer tegmentosum subcommunity, Saxifraga punctata subcommunity and typical subcommunity.

Inhibitory activities of 58 methanol extracts, which were prepared from different parts of 55 kinds of edible and medicinal plants, against human thrombin were evaluated. Analysis of the anti-coagulation activity determined by thrombin time enabled us to select 8 herb extracts as possible sources of anti-thrombosis agent. Further analysis of anti-thrombosis activity determined by activated partial thromboplastin time and fibrinolytic activity, and heat stability and inhibition against other proteolytic digestive enzymes provided new information that Pimpinella brachycarpa, Lysimachia clethroides, and Salix gracilistyla could be used as a potential anti-thrombosis agent. Our results suggest that edible and medicinal plants could be the potential source of thrombin inhibitor.

This research identified a disturbance regime caused by wild boar in a mature Quercus mongolica forest and analyzed the impact of this disturbance on the structure and distribution of herbaceous plants in Mt. Jeombong, Korea. We demonstrate that disturbance by wild boar was most frequent from winter to early spring, but also occurred year round. Areas which were frequently disturbed by wild boar included the mountain ridge, the mild slope on the north face, and sites with high concentration of Erythronium japonicum. The disturbance cycle by the wild boar in this region was estimated at approximately 2.8 years. The wild boar's reduced the community's species diversity and herbaceous coverage, and increased its evenness. This disturbance reduced the coverage of spring ephemeral; Veratrum nigrum var. ussuriense, Symplocarpus niponnicus, Anemone koraiensis and Corydalis turtschaninovii were particularly sensitive. In addition, summer green herbaceous plants such as Astilbe chinensis, Ainsliaea acerifolia, Meehania urticifolia, and Pimpinella brachycarpa were sensitive to the wild boar's. It was found that wild boar ate E. japonicum most selectively of all plants in this investigation area. In conclusion, together with micro-topography, wind, formation of gaps of a forest and rearrangement of litter layer, wild boar's disturbance is an important factor influencing the dynamic changes of an herbaceous community in a mature temperate hardwood forest.

To examine the allelopathic potentials of Chrysanthemum boreale, aqueous extracts and essential oil of the plant were used in these experiments. Seed germination of the receptor species was inhibited by the aqueous extracts and the inhibitory effect was increased in proportion to the concentration of extracts. In contrast, seedling elongation showed varied results. Achyranthes japonica, Bidens bipinnata, Raphanus sativus var. hortensis for. acanthiformis, Plantago asiatica, Pimpinella brachycarpa and Lactuca sativa were inhibited by increasing concentration of the aqueous extract, while Brassica campestris subsp. napus var. pekinensis and Echinochloa crus-galli were stimulated by the extract. Dry weight was also inhibited proportionally by increasing concentration of the aqueous extract, while some species were stimulated by a lower concentration of the extract. The volatile substances of C. boreale did not affect the seed germination of receptor plants, but seedling elongation and dry weight of some species were inhibited dose-dependently. Root hair development of selected plants was inhibited along with the concentration of essential oil. The above mentioned results, therefore, confirmed that the natural substances from C. boreale had allelopathic potentials to other plants.
