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.

The study was conducted to investigate the effect of cultivation area with different sea levels on essential oil in the root of Valeriana fauriei var. dasycarpa Hara (Valerianaceae). The total content of the essential oil was not different in various cultivation area, however, its composition varied. The major components were bornyl acetate and sesquiterpene alcohol in three cultivation areas. Among the valepotrate components known as major active components in Europe and Nepal valerian, valtrate was detected in a small amount, but the quantity was not changed.

This study was conducted to know the effect of soil moisture content on growth of aerial parts and root of Valeriana fauriei var. dayscarpa HARA in pot condition. The soil moisture contents were 30, 45, 55, 70, 80 and 90% of maximum water requirement. The result obtained are as follows; 1. Width and length of leaves in valerian were slightly increased with increase the soil moisture content, however, length of petiole and root were increased with soil moisture content up to 80%. 2. It showed the positive correlations between moisture content and root weight and extract content in root. 3. Optimum soil moisture content was 80 to 90% of maximum water requirement.

We established a practical method for rapid and large-scale production of Valeriana fauriei var. dasycarpa Hara roots by bioreactor culture and confirmed valerenic acids and valepotriates production. We also compared valerenic acids and valepotriates production patterns according to various media conditions. Among the media tested, B5 medium gave the maximum biomass production of 101 g fresh weight, which was a 5.03-fold multiplication rate obtained 4 weeks after inoculation of 20 g of fresh weight. The best production of total valerenic acids $(7.86\;mg/l)$ and valepotriates $(8.96\;mg/l)$ was B5 medium.

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 essential oil of Korean valerian root ( Valeriana fauriei roar. dasycarpa Hara) was isolated by simultaneous distillation Sl extraction. The oil content of fresh root was 0.7% (wb) and that of dried root was 2.1 5 (db) and sensory analysis of the oil indicated sweet-balsamic, woody and floral characteristic aroma notes. The oil was fractionated into one hydrocarbon fraction and three oxygenated hydrocarbon fractions by using silica gel column chromatograpy. Each fraction was analyzed by capillary GC and GC-MS. Out of 81 characterized compounds, the major compounds were a-pinene, camphene, $\beta$-pinene, bornyl acetate, borneol , bornyl iso-valerate and sesquiphellandrene and the characteristic floral and woody aroma of neutral fraction of Korean valerian root could be due to be the presence of oxygenated compounds such as borneol, bornyl acetate, bornyl iso-valerate, p-ionone ana $\beta$-ionone epoxide. Comparing the yield of Korean valerian root with those from other origins reported, oil content of Korean valerian root was higher than those of European and Indian origins.

Substance A, white prismatic crystal, mp $134{\sim}135,\;C_{29}H_{50}O$, substance B, white needle crystal, mp $131{\sim}132^{\circ},\;C_{17}H_{28}O_4$ and substance C colorless oils, bp $84{\sim}85,\;C_{15}H_{24}O$ were isolated from the underground portion of Valeriana fauriei var. dasycarpa $H_{ARA}$(Valerianaceae) according to Thies method. Substance A was confirmed as known sterol, ${\beta}-sitosterol$ by chemical and spectral discussions. Substance B was estimated as hitherto unknown sesquiterpenoid, 11-acetoxylhydroxyvaleranone by chemical and spectral discussions. Substance C was proposed as hitherto unknown sesquiterpenoid 1, 4-dimethyl-7-isopropenyl 4, 5, 6, 8, 9, 10-hexahydroazulene-1-ol by chemical and spectral discussions, and the general biogenetic considerations.

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 study was carried out to investigate the compositions of fatty acids, inorganic components and volatile organic acids from Korean valerian roots, Valeriana fauriei var. dasycarpa Hara and Valeriana officinalis var. latifolia Miq. The contents of total lipids ranged from 3.7 % to 4.5% and the major fatty acids were linoleic, linolenic and palmitic acid. Ash contents ranged from 4.3% to 6.3%. and the contents of Na, Fe, Zn and Cu showed some quantitative differences depending upon grown region or species. Fourty components were identified from acidic fraction of dichloromethane extract of V. fauriei var. dasycarpa Hara, of which the major components were 3-methyl butanoic, dimethoxy-2-propenoic. 3, 4-dimethoxy benzoic and 3-methyl pentanoic acid.

This study was conducted to establish standard fertilization rates for the cultivation of Korean valerian(Valeriana fauriei var. dasycarpa Hara) which is useful for medicinal and aromatic resources. Nitrogen, phosphate and potassium were treated with four application levels, 0, 6, 9, 12kg per 10a, and the growth characteristics, root yield and essential oil compositions of valerian were measured. The growth and root yield of valerian were the highest in the rate of 9kg per 10a for nitrogen, phosphate and potassium, respectively. Nitrogen had the most powerful effective followed by potassium and phosphate. The contents and compositions of essential oil also varied with the amount of fertilization. The contents of the essential oil was the highest in the application level of 9kg per 10a for nitrogen, phosphate and potassium, respectively. The essential oil compositions were affected by the fertilization rate.
