This experiment was conducted to investigate the effects of soil texture on agronomic characteristics and tuber yield in chinese yam (Dioscorea opposita Thunb). Tuber length and weight was greater and tuber shape was much better in sandy loam and loam soil than in sandy or clay loam soil. In loam and sandy loam soil, fresh tuber yield was increased by
in short-tuber type and 6% in long-tuber type, and large tubers yield (above 260g) was increased by
in short-tuber type and
in long-tuber type compared to those in sandy soil. There was no differences in large tuber yield at the 5% level of significance between loam and sandy loam soil. Malformation of tuber with bifurcation was extremely increased in sandy soil, and tuber diameter of long-tuber type was decreased in clay loam soil compared to those of the other soil texture.

On the purpose of development of antioxidative compounds from natural sources, 38 plants known to have antioxidant activity have been examined concerning DPPH radical scavenging activity. Among 13 plants exhibiting the activity, the seed of Carthamus tinctorius L, was selected as resources to search for active compounds due to rareness of study. The seed of the plant has been used as edible oil or preventive and remedial drugs for osteoporosis, arthritis. To reveal the principal component manifesting the antioxidant activity, the MeOH extracts was successively solvent-fractionated with EtOAc, n-BuOH and water. In order to isolate active component from the EtOAc fractions, application of silica gel column chromatographies and activity tests were repeated for a active component to be isolated. Its chmical structure was determined to be N-feruloylserotonin, a conjugated serotonin compound, by the interpretation of spectral data, NMR. MS and the adaptation of chemical reactions.

Morphological characteristics of nine Epimedium spp was analyzed on the basis of six morphological characters. To analyse the genetic relationship among Epimedium spp., polymerase chain reaction (PCR) was performed with total genomic DNA of 17 Epimedium spp. by using random 8 primers. The genetic diversity and genetic distance among nine Korean collections, seven Japanese and one China collection were used to generate a dendrogram showing phylogenie relationship. Seventeen Epimedium spp were classified into two groups of group I and II, since they were divided into two major groups at the similarity coefficients value of 0.65. In addition, one of the two group, group I was divided into three sub-groups including Epimedium koreanum, Chul-won collections 1, 2, and 3, Yanggu, Hongchon, Hwachun, Chunchon, China, Maehwa (Japanese), E. diphyllum and E. violaceum (Japanese), while group II included Chulwon collection 4 and 5 and Japanese collection. The samples collected at Chulwon district showed close similarity with Japanese collection. Similarity indexes between collection and genetic relationship were related at the levels ranging from 0.6 to 0.9.

This study was carried out to screen herbs among herbal plants showing antimicrobial activity against some food spoilage and pathogenic microorganisms. One hundred fifteen kinds of herbal plants were extracted by 70% ethanol, and then they have been screened for antimicroorganisms. Six herbal plants such as Salviae radix, Dryopteris rhizoma, Terminaliae fructus, Araliae radix, Psoraleae fructus and Schisandrae fructus showed strong antimicrobial activities against Bacillus subtilis. Antimicrobial activities were showed in Anemarrhena radix and Dryopteris rhizoma on Candida albicans, and in Anemarrhenae radix, Dryopteris rhizoma and Polygalae radix on Schizosaccharomyces sp. It was revealed that eight herbal plants such as Dryopteris rhizoma, Salviae radix, Sappan ligunum, Sinomeniae radix, Schisandrae fructus, Rhui fructus, Sophorae radix and Inulae radix also showed antimicrobial activities on Streptococcus mutans. In addition, Anemarrhena radix, Curcuma tuber, Inulae radix, Polygonum radix, Sanguisorbae radix, Scutellariae radix and Terminaliae fructus and showed antimicrobial activities on Trichophyton mentagrophytes. Four kinds of herbal plants such as Dropteris rhizoma, Salviae radix, Terminaliae fructus and Scutellariae radix which showed broad antimicrobial spectrums were mixed by 1 : 1 ratio with the other herbal paints showing relatively strong microbial activities such as Terminaliae fructus, Sinomeniae radix and Scutellariae radix etc. The extracts of mixed herbal paints showed higher antimicrobial activities than those of single herbal plant.

Korean Journal of Medicinal Crop Science, volume 8, issue 2, 2000, Pages 117~122
This study was carried out to know the factors affecting on shoot formation and rooting for stable and routine production of plantlets in bioreactor culture of Scrophularia buergeriana. Multiple shoots were formed effectively when explants were transplanted on the MS media with decreased concentration of
as 413mg/ l . Three hundred stem explants (0.8-1.0cm) was appeared as proper inoculation size in bioreactor culture. IBA (0.05mg/L) was more effective for rooting of the shoots in liquid as well as solid media. Six weeks long culture of explants in bioreactor gave better shoot shape for rooting on solid half-strength MS media.

Park, Ju-Hyun ; Chae, Young-Am ;
Korean Journal of Medicinal Crop Science, volume 8, issue 2, 2000, Pages 123~128
This study was carried out to determine factors affecting on the mass propagation of Rehmannia glutinosa seedlings in bioreactor culture. Air-lift type bioreactor was more compatible to shoot formation than stirrer type. Fifty grams(90 stem explants) of inoculum in 1.5L medium was placed into 2.5L bioreactor with aeration rate of 0.5 v.v.m., which was proper for effective shoot formation. Adding MES as pH buffer to culture medium increased the numbers of shoot formation. Adding 5g/l of anti-vitrifying agent into culture medium was highly effective for diminishing the rate of vitrification in shoots formed.

The experiment was conducted to increase germination of Agrimonia pilosa seeds, one of the natural medicinal plants, by various treatments, and also the effects of seed treatments on the growth of plants after sowing in field. The optimum temperature for germination of A. pilosa seeds was
after 20 days stratification duration at
, the germination rate than highest, 86% at that temperature. The stratification increased germination rate in all the temperatures treated, shortened
days of germination period and promoted more 20% germination rate than the other treatments. Flowing water, low temperature,
and NaOCl were not effective for germination and high temperature reduced germination rate. At the early growth stage, the plant height was taller
, one or more leaves were increased by the stratification treatments, and also stratification increased the number of leaves per plants 10 or more leaves compare with other treatments at harvesting stages. By stratification, the flowering date was 5 days earlier, June 18th than other treatments due to earlier sprouting.

Growth and ecological differences of some important medicinal plants (Carthamus tinctorius, Astragalus membranaceus, Digitalis purpurea, Melissa officinalis, Anethum graveolens, Angelica gigas and Saururus chinensis) were observed at the different attitudinal sites of Mt. Halla in Cheju from 1997 to 1998. Growth of all medicinal plants was generally higher in the northern slope parts than in the southern slope parts. But at 50m above the sea level in the northern slope regions, the germination, growth and yield of Astragalus membranaceus and Digitalis purpurea were reduced by the wind. As the altitude was higher, the temperature was more slowly down in the northern slope regions than in the southern slope regions, while, the moisture was relatively high. The growth of Carthamus tinctorius, Melissa officinalis, Anethum graveolens and Angelica gigas were generally reduced by the higher altitude. On the other hand, growth of Saururus chinensis was good at the 700m above the sea level.

Field experiments were conducted to investigate the yield and paeoniflorin content between healthy peony and blight plot of top part with every year during 3 years at June, July, August, September, separately. Stem length and diameter, No. of stem in the blight plot of peony were decreased in early in blight time compared with those in no blight growth. No. of flower buds per plant was 5.2, 4.6 in 3 year- grown and 4year-grown plots at late June blight compared with 11.5, 16.2 in no blight. No. of axillary flower was also similar to as above. Main root length and root diameter was most decreased in the plot of late June blight compared with healthy peony. No. of root more than 10mm of root diameter was small in order of blight time, namely Late June, July, August and September. The root dry yield of 4 year healthy peony was most high in 1,603kg per 10a, but it was lowed in 1,007kg in the plot lasted blight during 3years at late June. Paeoniflorin content was no different between 3year-grown and 4year-grown, but it was high in late June blight plot increased with the early in blight time.

The major components were isolated from the n-hexane, EtOAc and BuOH extract of Galla Rhois(Rhus Javanica Linne). Their structures were characterized as syringic acid, gallic acid methylester, protocatechuic acid, gallic acid and 1, 2, 3, 4,
. This study was carried out to investigate the biological activities of isolated compounds. Five compounds were tested for hepatoprotective effects on CCl4-induced cytotoxicity in primary cultured rat hepatocytes and antioxidative effect on Ferric-Thiocyanate method and TBA method. As a result, isolated five compounds showed stronger antioxidative activity than tocopherol, and the antioxidative activity of gallic acid methylester, protocatechuic acid and syringic acid were similar to that of BHA on Ferric-Thiocyanate method. Specially 1, 2, 3, 4,
showed stronger effect of lipid-peroxidation inhibition than BHA. Gallic acid appeared stronger inhibitory effect of malondialdehyde on TBA method. Hepatoprotective effect of 1, 2, 3, 4,
was similar or even higher than that of glycyrrhizin on primary cultured rat hepatocyte cytotoxicity.
