Decursin is a major component of the root of Angelica gigas(Umbelliferae), which has been traditionally used in Korea as a tonic and to treat anemia, hemiplegia, and women's diseases. The objective of this study is to identify the anti-cancer mechanism induced by decursin on apoptosis of human leukemia and lymphoma cells. Cytotoxicity of decursin on U937, HL-60, MOLT-4, THP-1 cells showed the significant effects. First of all, $IC_{50}$ of decursin on four cell lines was 27.1, 32.4, 17.4, $15.1{\mu}M$, respectively. So $IC_{50}$ in THP-1 cells was the smallest among 4 cell lines treated with decursin($15.1{\mu}M$). In order to understand the apoptosis-mechanism by decursin, we examined the gene expression of bcl-2(anti-apoptotic), bax(pro-apoptotic) and p53(tumor suppressor)after treating the THP-1 cells with decursin(10, 50 and $100{\mu}M$). It was found bcl-2 gene was decreased dose dependently, the expression level of bax gene of THP-1 cells treated with $100{\mu}M$ of decursin was about 3 times higher than those of control, and p53 gene was increased In the same concentration($100{\mu}M$), p53 gene was increased dose dependent manner. In protein express, bcl-2 and p53 protein showed a tendency to decrease. bax was increased about 4 fold. Therefore decursin is a useful chemotherapeutic agent against leukemia.

Taxonomy of umbelliferous taxa Heracleum moellendorffii complex has been unclear in their species delimitation in the far-eastern Asian regions. In both Korea and China Heracleum moellendorffii was adopted for their description while H. sphondylium was chosen to describe Japanese Heracleum. From Genbank accessions, taxa collected from Kamtchatka and Promorskiy, Russia were defined as H. maximum, endemic taxon to North America. In this study, we reviewed the taxonomy of Heracleum moellendorffii complex in Korea and neighboring countries on the basis of molecular phylogenies derived from sequences of nuclear ribosomal DNA internal transcribed spacer (ITS) regions. From three Korean accessions of Heracleum investigated in this study, two types of ITS sequences were obtained; two accessions were related to Chinese H. moellendorffii var. moellendorffii and North American H. maximum without forming a clade while the other one was identical to accession from H. maximum from Primorskiy, Russia. In the other hand, Japanese H. moellendorffii (=H. sphondylium ssp. sphondylium var. nipponicum in the flora of Japan) was closely related to H. maximum accessions from Korea and Russia, not nested within the clade comprising several subspecies of H. sphondylium. In order to delimit species boundaries among putatively closely related Heracleum species in fareastern Asian countries, more samples and much more rapidly evolved DNA regions must be investigated with interpretation of morphological and anatomical features.

This study was conducted to isolate a compound with anticancer properties from the roots of Peucedanum japonicum Thunb. (Umbelliferae), and to evaluate the efficacy of that compound's anticancer activity. The $CHCl_3$ layer was purified via repeated column chromatography and recrystallization. The two compounds isolated from $CHCl_3$ layer were identified via NMR spectroscopic analysis as (10E) 1,10-heptadecadiene-4,6-diyne-3,8,9-triol (Comp. I) and anomalin (Comp. II). (10E) 1,10-heptadecadiene-4,6-diyne-3,8,9-triol was the first report from the roots of P. japonicum. MTT assays were conducted to evaluate the in vitro cytotoxic activities of Compounds I and II against the following human cancer cell lines: HeLa, HepG2, SNU-16, and AGS. Comp. I evidenced the most profound cytotoxic activity against HepG2 cells ($IC_{50}=6.04{\mu}g/mL$), and Comp. II exhibited the most profound cytotoxic activity against SNU-16 cells ($IC_{50}=18.24{\mu}g/mL$) among the human cancer cell lines tested in this study. However, no significant cell death was observed in the CCD-25Lu human normal lung fibroblast cells. Quantitative analysis using UPLC (Ultra Performance Liquid Chromatography) showed that the roots of P. japonicum contained 0.015 (Comp. I) and 1.69 mg/g (Comp. II) of these compounds.

Hanyak, Korean herbal medicine is defined as the herbs understood and explained by traditional Korean medical theories. Considering this definition, there are broad prospective of every species being consilienced and utilized as Korean herbal medicine. Most varied plant species are in tropical regions, and its of these regions posses its own particular traditional medicine. Brazil posses the most varied and abundant plant species and also characteristic traditional medicine, formed by the combination of native indians and immigrants from Africa and Europe. Brazilian traditional medicine are practices by 'garrafeiros', 'raizeiros', or 'curandeiros' and in Caatinga uses herbs in ritual ceremonies. But threatened by modernization, these knowledge may be vanished in a prompt time. Therefore we carried this research in the propose of understanding as well as preserving their traditional medical knowledge. We revised publications about the medical plants and summarized 314 species of 94 families according to repetitive references. The most cited families were COMPOSITAE, LABIATAE, LEGUMINOSAE, RUBIACEAE, SOLANACEAE, UMBELLIFERAE, VERBENACEAE. Also cited major medical efficacies which further medical uses in combinations or modification of current traditional Korean medicine should be studied. This study provides overall prospect of the plants resources of Brazil and their uses. It may serve in the consilience and understanding of varied traditional medicine by traditional Korean Medicine.

This paper is intended as an investigation of the analysis of high-performance liquid chromatography and the method of extraction of decursin and decursinol angelate in Angelica gigas roots. There are three kinds of extraction methods: distilled water, 50% EtOH and 100% EtOH. The condition of HPLC was obtained on a reversed-phase column $(Polarity\;dC_{18},\;4.6{\times}250 mm,\;5\;{\mu}m)$ using a phosphate buffer-acetonitrile-sodium lauryl sulfate as the mobile phase. Under these chromatographic conditions, UV detector was 230 nm, column temperature $30^{\circ}C$ and the speed of a current 1.0 ml/min, respectively. The results of extraction with distilled water, 50% EtOH and 100% EtOH in Angelica gigas roots were as follows. The concentrations of decursin and decursinol angelate were 182 and 153 ppm (distilled water), 3,142 and 2,547 ppm (50% EtOH) and 3,341 and 2,778 ppm (100% EtOH). There were high positive correlations between the concentrations of decursin and EtOH (r=0.8928, p<0.01) and decursinol angelate and EtOH (r=0.9009, p<0.01).

Although the dried root of Saposhnikovia divaricata (Turcz.) Schischk. (Umbelliferae) is a popular medicinal plant in East Asia, there has been no systemic toxicological evaluation of a water extract of Saposhnikoviae Radix (SRE). In this experiment, an oral acute and 13-week subchronic toxicological evaluations of SRE (500-5,000 mg/kg body weight) were performed in both sexes of Crl:CD(SD) rats. Based on the results from mortality, clinical signs, effects on body weight and organ weight, clinical biochemistry, hematology, urinalysis, and histopathology, significant acute, 4-week repeated dose range finding (DRF) and 13-week subchronic toxicity of SRE was not observed in either sex of rats; thus, the no observed adverse effect level (NOAEL) was 5,000 mg (kg/day). To identify anti-hyperuricemia potential of SRE, the suppressive effect of SRE was determined in mice challenged with potassium oxonate (PO; 250 mg/kg) via intraperitoneal injection for 8 days (each group; n = 7). SRE supplementation suppressed the uric acid level in urine through significant xanthine oxidase (XO) inhibitory activity. Kidney dysfunctions were observed in PO-challenged mice as evidenced by an increase in serum creatinine level. Whereas, SRE supplementation suppressed it in a dose-dependent manner. Collectively, SRE was safe up to 5,000 mg (kg/day) based on NOAEL found from acute and 13-week subchronic toxicological evaluations. SRE had anti-hyperuricemia effect and lowered the excessive level of uric acid, a potential factor for gout and kidney failure.
