Scutellaria baicalensis G. was cultivated in plots of different soil textures which were sand loam(SL), loam(L) and clay loam(CL). Also three fertilizer conditions were used; non application (NA)treatment, rice straw manure(RSM) treatment and N-P-K, chemical fertilization(CF) treatment. The chemical-physical properties, such as organic matter, available phosphate,
, CaO, clay contents and porosity ratio in CL plot with RSM application were the most proper in CL plot and RSM application for the culture of S. baicalensis plants. RSM had very high contents of total nitrogen, 2.25% and C/N ratios, 21.4. Thus the growth of shoot and root in loam plot with RSM treatment were greater compared to that of CL plot with NA treatment. Whereas, The highest baicalin, baicalein and wogonin contents in roots were found in CL plot with RSM treatment. There was significantly positive correlation between aerial and underground parts of plant, yield and contents of T-N,
but negatively correlated with the contents of baicalin, baicalein and wogonin in S. baicalensis roots.

Germination of Codonopsis pilosula seeds and afterward their seedling emergence have been occasionally very poor due to their dormancy and structural defects. The study was done to determine the treatment effects of priming,
, agitation and washing during and after priming, drying and water imbibition after drying on germination of its seeds and then of the successive three combined treatment after priming on the its seedling emergence to model its presown seed treatment. While agitation at the speed of 10 rpm was made or not, priming using
under their different concentrations and light quality illuminated for 12 hours a day were done separately. Then their two best results were compared to determine the better one. Using the above determined best result, washing was done 3 minutes in the tap water or not, and drying of washed seeds was made under 4 different lights, and water imbibition of the dried seeds with differed period were successively done to deduce its presown seed treatment. In the comparison of the best germination rate of priming and
, the former showed considerably higher rate than the latter; the priming treatment was done at agitated
150 mM solution under darkness or 12 hour red light illumination a day for 2 days. Washing after priming enhanced the rate compared to no-washing. Drying was the best way at which seeds washed were desiccated under
and 4 hour red light illumination. Water imbibition immediately before sowing must be made for 2 days. Seedling emergence rate was the highest at the seeds from successive 4 treatments, priming, washing, drying and water imbibition before sowing of two others, the priming and washing, or the priming, washing and water imbibition, meaning that its presown seed treatment must follow the procedure of the above 4 successive ones.

The essential oils from the aerial parts of Tagetes minuta L. from two different locations in Korea were obtained by hydrodistillation in 0.52%(Goheung, Chonnam) and 0.48% yields(Puan, Chonbuk) as a dry weight base, respectively. A total of 69 components, accounting in 94.7% and 92.1% of the oil, respectively were identified by gas chromatography-mass spectrometric analysis and comparison of retention indices with those of authentic compounds. The main components in both samples(Goheung, Chonnam and Puan, Chonbuk) were limonene(5.83% and 6.41%, respectively),
(4.87% and 47.73%), dihydrotagetone(14.78% and 52.83%), trans-tagetone(0.64% and 2.99%), cis-tagetone(1.13% and 2.50%), trans-tagetenone(1.15% and 11.45%) and cis-tagetenone(0.69% and 1.41 %). Although these components were present in both samples, the results showed large differences in the percentage composition of these components.

This study was carried out to investigate antioxidative, antimicrobial activity and the effect on hepatotoxicity in various extracts of Artemisia iwayomogi. The herb has been used widely for jaundice, hepatitis and liver cirrhosis in chinese medicine. Solid yield by various extraction solvents, 18.1%, was the highest in water extract. To find antioxidative activity in Artemisia iwayomogi was estimated radical scavenging effect by DPPH method in various extracts and change of the POV(peroxide value) of various extracts added in soybean oil during 20 days at
. Radical scavenging effect by DPPH method was the most effective in methanol extract. Added 1,000ppm water extract and methanol extract in soybean oil, the POV of them, 46.8(meq/kg) and 50.8(meq/kg) were lower than that of control, 79.1(meq/kg), during 20 days storage. After antimicrobial activity of various extracts of Artemisia iwayomogi on bacteria was carried out by paper disc method, it found that the ethanol extract was the strongest activity on Vibrio parahaemolyticus. In vivo experiment was to investigate the effect of Artemisia iwayomogi water extract(AIWE) on hepatotoxicity by carbon tetrachloride
in rats. The experiment groups were divided into five groups for recovery(for 3 days) and three groups for protection(for 10 days) in rat liver. The weights and morphological changes of liver and the body weight were examined in each groups. Compared with
, liver and liver/body(%) weights of AIWE pretreatment groups for 3 days and AIWE posttreatment groups for 10 days were declined. In macrography, fibrious exudates and swelling of liver were decreased in AIWE treatment groups. Accumulation of lipid droplets and necrosis of hepatocytes were also decreased in AIWE treatment groups in microscopically. In these results, AIWE seems to enhance hepato-protective and recoverable effect on
induced hepatotoxicity in rats.

Crotalaria sessiflora is one of a few medicinal herbs among the legumes used as antitumor herb medicine but has lower seed germination and afterward seedling emergence. This study was carried out to elucidate the effects of cold stratification as presown treatment as well as
and acetone on its seed germination and seedling emergence. Cold stratification,
and acetone treatments were performed with different concentrations and period levels. Cold treatment was done under 14 hour red light illumination a day or darkness and the two others under darkness. On the basis of the best germination rate of each treatment,
and cold stratification treatments showed the highest germination rates at 0.1 mM but 12 hours and 2 week periods under darkness, respectively.
and acetone treatments came out at 400 mM and 200 mM lasted for, respectively. The best germination rates from
and acetone were comparatively higher than those from the former
and cold treatments. In evaluation of seedling emergence using the last two treatments,
treated seeds were better performed than acetone treated seeds showed somewhat higher germination rate, implying that presown seed treatments must be evaluated by the combination with indoor and field tests.

This study was conducted to compare volatile components from the ten kinds of basils cultivated in Korea. The ten kinds of basils were separated flower, leaf, and stem part from whole plants, respectively. All sample separated were extracted by simultaneous steam distillation-extraction method(SDE) and were analyzed by gas chromatography(GC) and mass selective detector(MSD). Total 42 components were identified in essential oils including 11 alcohols, 6 carbonyls, 20 hydrocarbons and 5 esters components. The major components were linalool, methyl chavicol, eugenol, trans-methyl cinnamate,
and 1,8-cineole. The content of linalool was high significantly in the flower
, the leaf and stem showed
, respectively. Especially, the content of methyl chavicol was high relatively in the leaf
, the flower and stem showed
, respectively. Articock, figz, glove, and greek basils were rich in eugenol
and poor in methyl chavicol
when compared with others kinds of basils. The composition of the components identified showed quite difference between kinds of basils, and the number of components identified in stem was much less than that in flower and leaf

Peony has been cultivated as medicinal plant in East and also its beautiful flower was acknowledged over the world. In West, numerous peony varieties were developed for ornamental use but not in the country. Ninety two varieties of ornamental peony were introduced from U.S.A. and investigated in Uisong Medicinal Plant Experiment Station during
. For most of them, their growth habit were good in the country. Their flower colors were clearer and stems were thicker and stronger than domestic peonies. Some of them showed vigorous growth and made very high yield of root. Most of varieties showed proper content of paeoniflorin, medicinal component of peony, for medicinal use.

This experiment was carried out to investigate the effect of rain shelter cultivation on growth characteristic and yield on Paeonia lactiflora Pallas. The sprouting time and flowering time of rain shelter cultivation were 9days and 15days, more quickly than that of field conditions, and stem length and number of stem per plant were many more or larger. The disease occurrence rain shelter cultivation was decreased of rust, anthracnose, powdery mildew and root rot disease compared to field conditions, and leaf spot disease was to similar. The root length, number of root and root diameter were to be good in the rain shelter cultivation. Root color and commercial ratio of rain shelter cultivation were better lighten and improved than field cultivation. Root yield of rain shelter was 2,395kg/10a, this was increased 9% and 27% respectively, compared to 2,201kg/10a, 1,892kg/10a of field A and field B.

Exogeneous application of pokeweed antiviral protein (PAP), a ribosomal-inacivating protein in the cell wall of Phytolacca americana (pokeweed) protects heterologous plants from viral and fungal infection. A cDNA clone of PAP introduced into Scrophularia buergeriana Miquel by thransformation with Agrobacterium tumefaciences. For plant transformation, explants were precultured on shoot induction medium without kanamycin for 2-5 day, and then they were cocultured with Agrobacterium for 10 minutes. The explants were placed on co culture medium in dark condition,
for 2days. After explants were washed in MS liquid medium, they were transferred into selection medium including kanamycin 50mg/L (MS salts+1mg/ l BAP+2mg/ l TDZ+0,2mg/ l NAA+MS vitamin+3% sucrose+0.8% agar, pH5.8). From PCR analysis, NPT II band was confirmed in transgenic plant genome and showed resistance against fungi in antifungal activity test. Micro assay to which protein extracted from transgenic line were added, revealed hyphae growth inhibition and no spore germination at high concentration. The characteristics of inhibited hyphae was represented transparent and thin. Expression of PAP in transgenic plants offers the possibility of developing resistance to viral and fungal infection.

Korean Journal of Medicinal Crop Science, volume 9, issue 2, 2001, Pages 166~172
This study was conducted to investigate the optimum condition of breaking dormancy and to increase the germination rate of Hovenia dulcis Thunb. seeds. Germination of seeds which did not germinate at the various constant temperature was induced by the artificial breaking of seed coat, and the germination rate of seeds which the seed coats were broken was the highest(94%) at
. The germination rate of seed was highest when seeds were treated with concentrated
for 40 minutes. When seeds were stored in dry condition, the germination capability was maintained up to 5 years after harvest. However, their germination rate become lowered and average germinating duration was extended. Germination rate of seeds which were stored for 5 years significantly increased by the low temperature treatment more than 30 days.
