In this study, two essential oils (EOs) extracted from Aleriana fauriei and Alpinia galangal were formulated as an emulsifiable concentrate (EC) and a granule. In the evaluation of their acute toxicity on fishes, Cyprinus carpio adults were used and the toxicities were determined in a static condition. The formulations were prepared from the essential oil extracted by three different methods namely steam distillation (SD), solvent extraction (SE) and supercritical fluid extraction (SFE). The acute toxicities were calculated using $LC_{50}$ values. Among EOs, only the EO extracted by solvent showed acute toxicities on carps. Some of the EC, EOs of Aleriana fauriei did not exhibit toxicity, while EOs from Alpinia galangal showed potent acute toxicities on carps. Among the granules, granules formulated with Aleriana fauriei EO extracted by SD method and Alpinia galangal EO extracted by SFE method showed acute toxicities on fishes. Nevertheless, $LC_{50}$ of ECs and granules formulated with all types of EOs in this study was higher than the fish toxicity level III for pesticides suggested by Korea Rural Development Administration. Furthermore, cytochrome P450 1A and glutathione S-transferase were confirmed as biomarkers in carps in response to the exposure to Alpinia galangal EO extracted by SD and SFE method, tracking Alpinia galangal EO in the aquatic environment.

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.

Chromosome analysis using karyotyping and bicolor FISH were carried out for two Maackia species (M. fauriei and M. amurensis) found in Korea. The somatic metaphase chromosome number was 2n = 2x = 18 in both, and the size of these chromosomes ranged from 3.58 to $5.82{\mu}m$. The chromosome complements consisted of two pairs of metacentric (chromosomes 1 and 7), four pairs of submetacentrics (chromosomes 4, 6, 8 and 9) and three pairs of subtelocentrics (chromosomes 2, 3 and 5) in M. fauriei but, chromosomes 4 (subtelocentric) and 7 (submetacentric) of M. amurensis have different morphology. Using bicolor FISH, a pair of 45S rDNA loci were observed for both M. fauriei and M. amurensis, but the number and site of the 5S rDNA signal were different in the two species. M. fauriei has two pairs of 5S signals on chromosomes 7 and 8 but, M. amurensis has four paris on chromosomes 3, 4, 7 and 7. Hence, the 5S rDNA is a useful FISH for Maackia species.

Ricania shantungensis is a pest causiong problems in many crops. We tested the possibility of controling Ricania shantungensis using essential oil of Valeriana fauriei which were extracted by three different methods (steam distillation, solvent and supercritical extraction). Steam distillation were showed the most high mortality to adult ($1,040{\mu}L/mL$) and nymph ($2,370{\mu}L/mL$) of R. shantungensis. The yield of steam distillation extraction was 0.67%, which was lower than other methods. However, it is determined that steam extraction was showed higher efficiency by considering time and cost. The result of this study showed the possibility of control R. shantungensis by essential oil of V. fauriei.

To explore the biological activities of Thalictrum alkaloids, a study was initiated to investigate the alkaloidal constituents from T. fauriei, a species indigenous to Taiwan. Extensive fractionation of the ethanolic extract provided three known aporphines, (+)-oconovine (Ia), (+)-isocorydine (Ib), and (+)-corydine (Ic) from nonphenolic tertiary base fraction. From quaternary base fraction two new protoberberinium salts, thalifaurine (IIa), dehydrodiscretine (IIb), in addition to magnoflorine (III), were isolated. The structure of both new compounds were confirmed by total syntheses. Fractionation of phenolic bases yielded a dihydromorphinandienone, (-)-ocobotrine (IV), as well as a novel aporphine-pavine dimer, tentatively named EP-10. The structure of EP-10 was established by means of 2D NMR studies. Preliminary study indicated a weak activity of lyzing Hela cells, in vitro, for EP-10.

A lectin has been purified from the bark of the legume Maackia fauriei. This lectin, MFA, was found to agglutinate human ABO erythrocytes at a titer of 256. The results from electrophoretic analyses, gel-filtration chromatography, and enzyme linked lectinsorbent assay indicate that MFA is an acidic glycoprotein, and exists as a tetramer of 30 kDa subunits that are linked by noncovalent bonds. The activity of MFA is critically dependent upon CaC1$_2$. MFA demonstrated high homogeneity with the lectins from M. amurensis, which is the only legume source of lectins that bind to sialoglycoconjugate, in its N-terminal amino acid sequence and amino acid composition, (omitted)

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.
