Agastache rugosa, a member of the mint family (Labiatae), is a perennial herb widely distributed in East Asian countries. It is used in traditional medicine for the treatment of cholera, vomiting, and miasma. This study assessed the genetic diversity and population structures on 65 accessions of Korean mint A. rugosa germplasm based on inter simple sequence repeat (ISSR) markers. The selected nine ISSR primers produced reproducible polymorphic banding patterns. In total, 126 bands were scored; 119 (94.4%) were polymorphic. The number of bands generated per primer varied from 7 to 18. A minimum of seven bands was generated by primer 874, while a maximum of 18 bands was generated by the primer 844. Six primers (815, 826, 835, 844, 868, and 874) generated 100% polymorphic bands. This was supported by other parameters such as total gene diversity ($H_T$) values, which ranged from 0.112 to 0.330 with a mean of 0.218. The effective number of alleles ($N_E$) ranged from 1.174 to 1.486 with a mean value of 1.351. Nei's genetic diversity (H) mean value was 0.218, and Shannon's information index (I) mean value was 0.343. The high values for total gene diversity, effective number of alleles, Nei's genetic diversity, and Shannon's information index indicated substantial variations within the population. Cluster analysis showed characteristic grouping, which is not in accordance with their geographical affiliation. The implications of the results of this study in developing a strategy for the conservation and breeding of A. rugosa and other medicinal plant germplasm are discussed.

The binding properties and sequence selectivities of ${\Delta}{\Delta}$- and ${\Lambda}{\Lambda}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ (bip = 4,4'-biphenylene (imidazo [4,4-f][1,10]phenanthroline) complexes with $poly[d(A-T)_2]$ and $poly[d(G-C)_2]$ were investigated using conventional spectroscopic methods. When bound to $poly[d(A-T)_2]$, a large positive circular dichroism (CD) spectrum was induced in absorption region of the bridging moiety for both the ${\Delta}{\Delta}$- and ${\Lambda}{\Lambda}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ complexes, which suggested that the bridging moiety sits in the minor groove of the polynucleotide. As luminescence intensity increased, decay times became longer and complexes were well-protected from the negatively charged iodide quencher compared to that in the absence of $poly[d(A-T)_2]$. These luminescence measurements indicated that Ru(II) enantiomers were in a less polar environment compared to that in water and supported by minor groove binding. An angle of $45^{\circ}$ between the molecular plane of the bridging moiety of the ${\Delta}{\Delta}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ complex and the local DNA helix axis calculated from reduced linear dichroism ($LD^r$) spectrum further supported the minor groove binding mode. In the case of ${\Lambda}{\Lambda}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ complex, this angle was $55^{\circ}$, suggesting a tilt of DNA stem near the binding site and bridging moiety sit in the minor groove of the $poly[d(A-T)_2]$. In contrast, neither ${\Delta}{\Delta}$-nor ${\Lambda}{\Lambda}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ complex produced significant CD or $LD^r$ signal in the absorption region of the bridging moiety. Luminescence measurements revealed that both the ${\Delta}{\Delta}$- and ${\Lambda}{\Lambda}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ complexes were partially accessible to the $I^-$ quencher. Furthermore, decay times became shorter when bis-Ru(II) complexes bound to $poly[d(G-C)_2]$. These observations suggest that both the ${\Delta}{\Delta}$- and ${\Lambda}{\Lambda}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ complexes bind at the surface of $poly[d(G-C)_2]$, probably electrostatically to phosphate group. The results indicate that ${\Delta}{\Delta}$- and ${\Lambda}{\Lambda}-[{\mu}-Ru_2(phen)_4(bip)]^{4+}$ are able to discriminate between AT and GC base pairs.

This paper has shown the experimental results about the physiological activities of water-, ethanol-, ethyl acetate-soluble fractions from ethanolic extracts of leaves, stems and roots of Cudrania tricuspidata on the skin, which has been used for a long time as a traditional herb medicine in Korea and China. The effects of these fractions on the secretion of nitric oxide and cytokines from macrophage(RAW 264.7 cell) exhibited that the ethyl acetate and water fractions from leaves inhibited the release of nitric oxide, all fractions inhibited thoses of inflammatory cytokine $IL-1{\alpha}$, and the ethyl acetate fractions of leaves, stems and roots inhibited thoses of inflammatory cytokine IL-6. The only ethylacetate fraction of leaves demonstrated significantly the reduction of melanin synthesis in melanoma cells. In order to evaluate the efficacy of collagen synthesis, the treatment with extracts on the human normal fibroblast cell(CCD-986sk cell) resulted in finding that the water fractions of leaves, stems and roots and the ethanol fractions of leaves and stems showed the increased synthesis of collagen.

Rhodiola sachalinensis is one of the most popular oriental medicines in East Asia. It is a perennial herb, belonging to the family Crassulaceae, which is mainly distributed in mountains at the altitudes of 1700-2500 m in Baek-Du mountain. Cultivation of this species for the production of medicine materials is not easy in nature, because of restrict habitats. In vitro production of roots can be applicable for the production of medicinal materials. Here, we investigated the optimal conditions for induction and proliferation of adventitious roots in in vitro culture system. Leaf, stem and root segments from R. sachalinensis were cultured on Murashige and Skoog(MS) medium supplemented with the various concentrations of IBA(Indole-3-butyric acid)(0.5, 1.0, 3.0, and 5.0 mg/L) and sucrose(10, 30, 50, and 100 g/L). The optimal explant for adventitious root induction was leaf segment. Induction of adventitious roots was highest on MS medium supplemented with 5.0 mg/L IBA and sucrose 30 g/L. In liquid culture, fresh weight of adventitious roots was highest(15.65 g) on 1/3 strength MS liquid medium supplemented with 5.0 mg/L IBA with 30 g/L sucrose. These results revealed the first attempt for the production of adventitious roots in R. sachalinensis.

This study was to investigate the chemical properties and nitrite scavenging and acetylcholinesterase inhibitory activities from Salicornia herbaciea seed. The lactic acid content of seed was about 2.0 fold higher than that of stem. Among various free sugars, the maximum fructose of seed, glucose of stem, and mannose contents of root were obtained, 176.3, 125.6, and 112.8 mg/100g, respectively. The maximum leucine content of seed among the essential amino acid was obtained, 853.7 mg/100g, which was about 3.0 or 6.0 folds higher than that of root or stem. In the case of glutamic acid of seed, it was 2,388.7 mg/100g, which was 5.6 or 9.8 folds higher han that of root or stem. The ratio of essential amino acid and total amino acid of seed was 30.14%. The ${\gamma}$-aminobutyric acid contents of seed, stem, and root were 43.87, 23.88, and 27.8 mg/100g, respectively. The catechin content of seed was an order of epigallocatechin (723.2 mg/100g) > epigallocatechingallate (654.3 mg/100g) > epicatechin (443.5 mg/100g) > gallocatechin (314.1 mg/100g). Especially, the non-gallated catechins content was about 2.0 folds higher than that of gallated catechins content. The nitrite scavenging activity of seed increased from 38.7 to 65.9% when the hot-water extract content of seed at pH 1.2 increased from 1.0 to 5.0 mg/mL. However, it was decreased to 25.7% at pH 6. The acetylcholinesterase inhibitory activity of seed was increased from 13.2 to 44.6% when the extract content increased from 20 to 100 mg/mL. These results show that S. herbaciea seed has a good potential to be used as a source of material or additive in cosmetics, food, and drug compositions.

Codonopsis lanceolata ("Deoduck" in Korea) is a perennial herb, and belongs to family, Campanulaceae. Its taproot is used a good source of a wild vegetable as well as an herbaceous medicine. In this study, to develop a bialaphos-resistant transgenic Codonopsis, seed germination mechanism and somatic embryogenesis of the plant were investigated, and Agrobacterium-mediated transformation with bar gene encoding phosphinothricin acetyltransferase (PAT) was performed. Attempt were made to regenerate plant from cells via somatic embryogenesis. When the cotyledons, nodes and leaf disks were cultured on MS medium containing 2,4-D and zeatin, embryogenic calli were induced. Upon transferring the somatic embryos to N6 solid medium without plant growth regulators, they developed into plantlets under continuous illumination. All plants were dead on MS basal medium containing 10 mg/L phosphinothricin (PPT) and Basta, respectively. The explants did not produce calli in the medium containing 200 mg/L kanamycin. The explants were cocultured with Agrobacterium tumefaciens for 2 days, and transformants were selected in MS basal medium containing 1.0 mg/L 2,4-D, 100 mg/L kanamycin and 500 mg/L carbenicillin. After the selection, embryogenic calli were induced and then somatic embryos were produced by subsequent subculturing. The somatic embryos were germiated on N6 basal medium containing 200 mg/L kanamycin and 500 mg/L carbenicillin. PCR analysis showed that nptII and bar genes were introduced in the Deoduck transformants. After the confirmation of bar gene expression in RNA and protein level, the transgenic Deoduck will be used to study the genetics of filial generation with the herbicide control gene, bar.gene, bar.

In the present study, the substance that show anti-proliferation of cancer cells as well as anti-oxidant and anti-inflammatory effect was searched. As a results, the methanol extract of Pogostemon cablin (P. cablin), is a well-known herb for traditional medicine in Korea and China for treating the digestive disorders, less of appetite, vomiting and diarrhea, inhibited the growth of various cancer cells such as A549, HepG2, MCF7 and HT29 cells. Cytotoxic effect of methanol extraction of P. cablin was excellent in A549 cells. P. cablin extract induced cell cycle arrest at G1 phase of A549 in a dose dependent manner. And it induced phosphorylation of p38 and Cdc25A and reduced expression of Cdc25A, Cdks, Cyclins and phospho-Retinoblastoma (Rb) proteins. Therefore, P. cablin extract seems to act through the p38 - Cdc25A - Cdk - Cyclin - Rb pathway in A549 cells. In addition, P. cablin extract showed anti-oxidant effect by DPPH free radical scavenging assay and anti-inflammation effect by inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) in RAW 264.7 cells in a dose-dependent manner. Taken together, these results suggest that P. cablin may be used as not only candidate materials for anti-cancer, anti-inflammatory and anti-oxidant, moreover, it would be possible utilized in various health functional food materials.
