To investigate the constituents of following plants, Valeriana fauriei species, which are V. fauriei var. fauriei $H_{ARA}$, V. fauriei form. coreana $H_{ARA}$ and V. fauriei var. dasycarpa $H_{ARA}$, we carried out gas-liquid chromatographical analysis of the volatile oils of these plants and found that camphene, l-bornylacetate, ${\alpha}-pinene,\;{\beta}-pinene$, d,l-limonene, l-borneol and ${\alpha}-kessylacetate$ were common components in their volatile oils. However, their terpenoidal composition was considerably different from ${\alpha}-kessylacetate$ in V. faurie var. fauriei, from kessanol, ledol, kessoglycol and nardol in V. fauriei var. dasycarpa, and from kessoglycoldiacetate, ${\alpha}-kessylalcohol$, faurinone and terpineol in V. faurie form. coreana. It was found by gas-liquid chromatography that the terpenoidal patterns of these Korean valerians were similar to those of Japanish valerians.

This study was conducted to know the effect of cultivation area with different sea levels on essential oil content and its composition and content of major active compounds in Valerian fauriei var. dasycarpa HARA and Valerian officinalis L. The total contents of essential oil were not different according to the locality in both valerian, however, its compositions were varied. The major components in V. fauriei were detected bornyl acetate and sesquiterpene alcohol in three cultivation areas. The major compounds were borneol, borney acetate, ${\beta}\;-sesquiohellandrene$ in V. officinalis other. Among the valepotrate components known as major pharaceutically active components in Europe and Nepal valerian, valtrate was detected in a small amount in V. fauriei, but its quantity was not changed according to the cultivation area.

In this study the essential oil and pharmacologically active components of different valerian species (Valeriana fauriei var. dasycarpa Hara and V. officinalis L. from Korea and V. wallichii DC from Nepal) were analyzed to search for native plant resources that can be used for medicinal herb and tobacco flavoring. The oil contents in dry roots of V. fauriei, V. officinalis and V. walhchii were 1. 71%, 0. 82% and 0. 83 %, respectively. The composition of the essential oil among different valerian species was compared. In V. fauriei 47 compounds were identified, while 21 and 25 compounds were identified in V. officinalis and V. wallichii. The major compounds in the oil of V. fauriei were bornyl acetate (33.8%) and camphene (10.8%), cedrol (4. 1 %), -pinene (3. 2%) and unidentified sesquiterpene alcohol (3. 0%). The major compounds were borneol (62. 5%) and ${\beta}-sesquiphelandrene$(6. 8%) and spathulenol (2. 1%) in V. officinalis, and borneol (74. 3%) and ${\alpha}-elemene$ (2.7%) and -sesquiphellandrene (2. 3%) in V. wallichii. Among the components known as major pharmacologically active compounds in European or Japanese valerian roots, valeranone, valerenal and -kessyl acetate was detected in a small amount in V. fauriei, but kessoglycol diacetate was not detected in V. faudei and V. officinalis Among the valepotrate compounds, major pharmacologically active components in V. wallichii, valtrate was detected in a small amount in V. fauriei and V. officinalis., and detected 1. 42% in V. wallichii. Didrovaltrate was also detected in the three valerian species tested, but acevaltrate was not detected except V. wallichii. On the other hand, antioxidative activity was slightly higher in V. fauriei than those of V. officinalis.

This study was conducted to know the effects of light intensity and temperature on growth of V. fauriei plants. Photosynthesis of V. fauriei had highly significant relations to light intensity and temperature in a quadratic regression model, from which the optimum light intensity and temperature for the plant growth were estimated to be 40,000lux and $17.7^{\circ}C.$ Root was produced less by shading at Jinbu where is located in alpine region, but root yield is increased by shading at Umsong where is located in plane region. Roots were produced more in Jinbu than in Umsong. A highly significant quadratic regression was noted between temperature and leaf width or root weight of V. fauriei. It was estimated from the regression equation that the optimum temperature for root growth was $20.3^{\circ}C.$

Distribution of Juncus fauriei L$\acute{e}$v. & Vaniot were restricted in Japan and Russia in previous literatures. We found its new distribution in the Korean peninsula: wet meadows of sandy seashore in Ha-Jo-Dae, Kangwon province. The plants have flattened stems (usually coiled) and black-colored margin in tepals. These are key characters to distinguish J. fauriei from J. decipiens, J. setchuensis, J. haenkei, and J. brachyspathus, which are closely related Korean taxa in the section Juncotypus. We provide description, distribution, and detailed photos of J. fauriei, and key for Korean taxa of sect. Juncotypus. The plant is named as "Geom-Jeong-Nap-Jak-Gol-Pul" in Korean.

Background: Valeriana fauriei (Valerianaceae) has been used to as a traditional medicine to treat a variety of symptoms, including headache, insomnia, hypertension, and menstrual irregularity. However, the present study investigates the species' antioxidant activity and its inhibition of oxidative DNA damage, which have yet to be studied. Methods and Results: The antioxidant activity was assessed using radical scavenging assays with 1,1-diphenyl-2-picryl hydrazyl (DPPH) and, 2, 2'-azino-bis (3-ethylbenzothiazoline-6 sulfonic acid) diammonium salt (ABTS) and a reducing power assay. The total phenol content was also analyzed, and phenolic compounds were detected using HPLC/UV, whereas the inhibitory effect of Valeriana fauriei on oxidative DNA damage was measured using ${\phi}-174$ RF I plasmid DNA cleavage assay. The DPPH and ABTS radical scavenging activity were $75.17{\pm}3.55%$ and $95.83{\pm}0.63%$, repectively, and the reducing power was $93.14{\pm}1.74$ at $200{\mu}g/m{\ell}$. The total phenol content was $10.24{\pm}0.04mg/g$, whereas chlorogenic acid, catechin, caffeic acid and epicatechin were identified using HPLC/UV, and the ${\phi}-174$ RF I plasmid DNA cleavage assay indicated that V. fauriei provided protection against oxidative damage. Conclusions: The results of the present study suggest that V. fauriei has powerful antioxidant activity that can provide protective effects against the oxidative DNA damage caused by free radicals. The species, therefore, provides a valuable resource for the development of natural pharmaceutical to treat aging, cancer, and degenerative diseases.

This study was carried out to know the effect of air temperature on photosynthesis and growth of Korean Valerian (valeriana fauriei var. dasycarpa HARA). The results are as follows; 1. Photosynthesis of V fauriei had highly significant relation to temperature in a quadratic regression mo­del, from which the optimum temperature for the plant growth were estimated to be $17.7^{\circ}C$. During the day­time in the field condition, the photosynthesis rate was highest at 9 a.m, then reduced to minimum at 2 p.m., and increased again thereafter. 2. Number of stomata was about $25/mm^2$ on the upper side and $85/mm^2$ on the lower side of the leaf, and the size was $21{\sim}30/{\mu}m$ in diameter. 3. A highly significant quadratic regression was noted between temperature and leaf width or root weight of V. fauriei. It was estimated from the regression equation that the optimum temperature for root growth was $20.3^{\circ}C$.

The contents of valepotriates, valerenic acid and their derivatives as mild sedative and antispamodic principles in two Korean valerian roots (Valeriana officinalis var. latifolia Miq. and V. fauriei var. dasycarpa Hara) were investigated and were compared with those in European valerian roots(Valeriana officinalis L.) by BPLC method. Among valepotriate compounds, valtrate was detected as a small amount in two Korean valerian roots, and iso-valtrate and dihydrovaltrate were detected as a trace amount. Among valerenic acid and their derivatives, valerenic acid were contained from 0.9∼3.46 mg/g base on dry weight. Over the vegetation periods investigated, the content of valepotriates remained more or less constant, hut the content of valerenic acid reached its maximum in 3-year old age. The compound isolated from Korean V. officinalis var. latifolia was elucidated as valerenic acid by spectroscopic data such as GC-MS, $^1$H-NMR and $^{13}$ C-NMR, and comparison of GC retention time with that of authentic compound.

This experiment was conducted to obtain information for the cultivation of Korean valerian(Valeriana lauriei var. dasycarpa Hara) which will be useful for medicinal and aromatic resources. The effect of different temperature conditions, light intensities and soil water conditions on growth, yield and component of essential oil of V. fauriei were measured at the Dankook University, Cheonan, and a study on the shading treatment was at Umsung, Chungchongbukdo, and Jinbu, Kangwondo, in 1995. V. laudei was planted at five different temperature conditions, 10, 15, 20, 25 and 3$0^{\circ}C$, eight light intensity conditions, 1, 000, 2, 500, 5, 000, 20, 000, 30, 000, 40, 000, 50, 000 and 60, 000lux, six soil water contents, 30, 45, 55, 70, 80 and 90％ of the saturated soil, during growth stage. Shading treatment was three conditions, 0, 25 and 50％, during the daytime in field conditions. Photosynthesis had a highly significant relationship with temperature conditions in a quadratic regression model, from which the temperature for the plant growth was estimated to be 17.7$^{\circ}C$. A highly significant quadratic regression was noted between temperature and leaf width or root weight of V. fauriei. It was estimated from the regression equation that the optimum temperature for root growth was 20.3$^{\circ}C$. The content of essential oil and extract rate of root was the highest in the 15~2$0^{\circ}C$. Photosynthesis also was significantly affected by light intensity in a quadratic regression model, from which the optimum light intensity for the growth was estimated to be 40, 000lux. Root yield was more produced in Jinbu than that of in Umsung. The root yield was increased by the shading treatment in Umsung, whereas it was decreased by the shading treatment in Jinbu. The content of essential oil was not affected by the shading treatment of plants during the cultivation, while the compositions of components of essential oil were related to the growing locations. As soil water content was higher, the growth and content of root extract were increased. The optimum soil moisture for the growth of V. fauriei was 80~90％ of the saturated soil. In summary, the results indicated that the growth, yield and component of essential oil in V. fauriei were affected by environmental factors as well as soil moisture.

Effects of various concentrations of elicitors for enhancement in valepotriates and valerenic acids production in adventitious root culture of Valeriana fauriei were investigated. Although the growth of adventitious roots was suppresed by addition of biotic or abiotic elicitors, the production of valepotriates and valerenic acids was enhanced. Addition of $100\;{\mu}M$ methyl jasmonate or 1 $g/{\ell}$ yeast extract to the root culture of V. fauriei resulted in the optimal production of valepotriates ($12.56\;{\pm}\;0.78\;mg/{\ell}$) and valerenic acids ($10.63\;{\pm}\;1.1\;mg/{\ell}$), respectively.
