The study of genetic diversity was carried out in Atractylodes japonica
. Although this species has been regarded as medically important one, there is no report on population structure in Korea. Starch gel electrophoresis was used to investigate the allozyme variation and genetic structure of eight Korean populations of this species. Of the 15 genetic loci surveyed, nine (60.0%) was polymorphic in at least one population. Genetic diversity was high at the species level
, whereas, that of the population level was relatively low
. Nearly 87% of the total genetic diversity in A. japonica was apportioned within populations. The sexual reproduction, high fecundity, and perennials are proposed as possible factors contributing to high genetic diversity. The indirect estimated of gene flow based on Gst was 1.69.

Concentration of quercetin and soluble tannin in Houttuynia cordata were determined at different growth stages as well as plant parts and application amounts of compost. Both contents of quercetin and tannin at growth stages were decreased before flowering time but slightly increased after flowering. The both contents of components in Houttuynia cordata collected on April 20 were shown to be markedly increased compared to those collected in May or June. The contents of quercetin and tannin at different organs were the highest in the flower. In the experiment of application amounts of compost, as application amounts is increased, fresh weight of aerial part was increased but the contents of quercetin and tannin were decreased. The contents of quercetin and tannin were the highest with 0.67% and 2.3%, respectively, in the compost non-treatment.

The seeds of Coix lachryma-jobi Linne var. mayuen Stapf. are used as dietary food for obesity and diabetes under the names of Yulmu in Korea and Yiyiren(薏苡仁) in China. It is one of the drugs promoting diuresis to eliminate the wetness-evil from the lower warmer in the traditional Korean medicine. According to ancient textbook of the traditional Korean medicine, it should be applied to patients with phlegm and heat, etc. The establishment of the method for the discrimination of Coisis Semen is very important for the quality control of drugs. Random amplified polymorphic DNA(RAPD) analysis and anatomical characteristics were used for the discrimination of Coix lachryma-jobi
. and C. lachryma-jobi
. In the RAPD analysis with 20 primers, 8 primers gave informative and reproducible bands with the genomic DNA. From the cluster analysis, the genus Coix were divided into two groups at similarity coefficient of 0.863.

Effect of pretreatment processing (peeling time, drying temperature, sample type) on the quality of hot air drying peony roots was investigated. Peony roots were peeled for 0, 10, 20, 30, 60, 90 and 120 minute in the peeling machine after water washing. Sample types were whole or cut (thickness of 3mm). Temperatures of hot air drying were 30, 40, 50 and
The level of water contents in dried sample was
. Drying time was muth reduced as the peeling time, cutting sample types and higher temperature. Contents of paeoniflorin were maintained highest amount (3.48%) in the non-peeling cut sample dried at
and lowest amount (2.29%) in the 120min-peeling whole one dried at
. Skin color of dried peony roots was heavily discolored in the sample of non-peeling whole type dried at
and the color was dark brown
. When considering shortening of drying time, preservation of active compounds and maintenance of color, the best pretreatment method of drying in peony roots was non-peeling, cut type processing.

Epimedium koreanum Nakai(EKN) has traditionally been well-known as a herbal medicine for the promotion of stamina and the improving sexual activity of human in oriental countries including Korea and China. The aim of this study was to investigate the effect of dietary supplementation of EKN water-extract(0.025%,w/v) on age-related change of xenobiotic metabolizing system in rat liver. Long-term supply of the EKN extract to rats did not induce any discernible signs. However, the mass of liver and kidney were slightly increased by the dietary supplementation. Level of cytochrome P450, NADPH cytochrome P450 reductase, P450 dependent ethoxycoumarin O-deethylase benzphetamine N-demethylase and glutathione-S-transferase in liver were decreased with age, but, these activities in 24 months of age were declined more in rats supplied with EKN extract. Level of cytochrome b5 and NADH-cytochrome b5 reductase were also decreased with age, however, there was no significant difference between with and without EKN extract. These results indicate that long-term supplementation of EKN extract to rats from weaning to 24 months may be a burden on the liver function in old age, and may aggregate the decline of xenobiotic metabolizing enzymes activities in old age.

GABA tea which was increased of GABA by anaerobic conditions in green tea leaves) was fed in the diet to spontaneously hypertensive rats(SHR). The mean systolic blood pressure of SHR fed a diet containing 1.5% GABA tea after 3 weeks was not different with zero day as 177.3mmHg. However, 1.5% green tea and control after 3 weeks were more increased 4.2 percents and 10 percents than in zero day. The plasma levels of aldosterone of SHR fed a diat containing 1.5% GABA green tea after 3 weeks was more decreased 2.5 times than in water treatment.

An efficient and reproducible procedure for the large scale propagation of Hovenia dulcis Thunb. is described. Shoot primodia emerging from the leaf surface was induced from MS medium supplemented with NAA. Stem cuttings were suitable explants for multiple shoot proliferation. They produced axillary shoots which branched repeatedly, yielding an average of 7 shoots per explants after 4 weeks in culture, when cultured on a woody plant medium (WPM) containing 0.1mg/l BA and 0.1mg/l NAA. Stem, leaf and root segments from axenic seedlings were used as explant source to induce somatic embryogenesis. A high frequency of somatic embryos were induced directly from leaf in MS medium with NAA, 2,4-D and in medium containing NAA, 2,4-D with BA. Somatic embryos were germinated in MS medium supplemented with 1mg/ l
. Somatic embryos proliferated secondary somatic embryos rapidly after transfer to MS medium supplemented with 1mg/ l kinetin, 1mg/ l
and 2% dextrose.

In DNA level, genetic study of Angelica species was firstly conducted to discriminate the bolting-resistant or low bolting variety, so called as Manchu, from other Korea collected lines and also this technuque was applied to identify the origin of commercial dried materials obtained from current oriental medicinal market. By RAPD analysis with 72 primers including sixty of 10-mers and twelve of 20-mers, respectively, three primers, which were related to the bolting resistant traits of Angelica gigas, were identified. Comparing the RAPD bands, URP04 primer showed the 1.7 kb specific band, which seemed to be related to delaying bolting traits, since it was observed only in Jinbu elite lines but not in others. On the other hand, since 1.2 kb band amplified by OPD11 was observed in other collected lines but not in Manchu var. and Jinbu line, this primer also could be considered as a selection marker for identifying bolting resistant or delaying bolting traits. In the same manner, since OPP09 did not show 1 kb major band but produced 0.8 kb and 1.2 kb bands in Manchu var., these three bands amplified by the primer could be considered one of the important key specifying Manchu var. related with the trait of Angelica gigas. OPC02 primer showed the same band patterns in all Korean collected lines, but not in other foreign introduced lines, such as A. sinensis from China, and A. acutiloba from Japan. Since these four RAPD primers, OPD11, OPP09, URP04, and OPC02 showed the specific polymorphisms in Angelica species, thus, these were useful to discriminate the three Angelica species, A. gigas, A. sinensis, and A. acutiloba.

The biological activities of immune modulating activities of the extracts from Echinacea purpurea, Chrysanthmum indicum L. and Circium japonicum var. ussuriense KITAMURA were compared. About 70% of the growth of human hepatocarcinoma and 80% of human gastric cancer cell was inhibited in adding 0.5mg/ml of the ethanol extracts of Echinacea purpurea, Chrysanthmum indicum L. and Circium japonicum var. ussuriense KITAMURA, respectively. The growth of human breast cancer cells was also inhibited in adding 0.5mg/ml of the extracts as well as 60% of the human cancer cells. It was proved that the growth of human normal lung cell, scored as 15% for the extracts. Overall selectivity of the extracts on several human cancer cell line was over 3, which is higher than those from the conventional herbs. The growth of both human immune B and T cells was enhanced up to 1.4 to 2.0 times by adding the extracts, compared to the controls. The secretion of tumor necrosis
from T cell was also increased up to 94 pg/ml in adding the Echinacea purpurea ethanol extract (0.5mg/ml). Circium japonicum var. ethanol extract also increased up to about 96 pg/ml of interleukin-6(IL-6) from B cell.

Pen-tsao-kang-mu(Bon-cho-kang-mok), chinese medicinal plant book, was written by Si-jin Lee, 1578, China. The subject of this study were 210 articles of grain part in Pen-tsao-kang-mu. Among them only 193 articles were able to be identified by authority of several references. By Engler's system they were classified into 4 divisions, 5 classes, 3 subclasses, 28 orders, 17 suborders, 46 families, 95 genera, 100 species, 11 varieties and 1 form, and were confirmed 112 kinds of original plants. Among the divisions, angiospermae was the most numerous division with 107 kinds(91.98%) and the second division was gymnospermae with 3 kinds(2.70%). The next were phaeophyta and fungi with 1 kind(0.90%) on each. Other 17 articles were unable to be classified because of their ambiguous name.
