  • The essential oil was extracted from the roots of Angelica dahurica Bentham et Hooker f. by steam distillation and its composition was analyzed by GC-MS. The antifungal activities were evaluated by micro-dilution method against five Aspergillus and three Trichophyton species. The most abundant component was ${\alpha}$-pinene (17.21%) among 40 compounds identified in this oil. The essential oil fraction of A. dahurica and ${\alpha}$-pinene exhibited marked inhibiting activities against the tested Aspergillus and Trichophyton species with MICs (minimum inhibitory concentrations) between 0.12 mg/ml and 8 mg/ml.

  • Several coumarins isolated from Angelica sp. were described to show inhibitory effects against human platelet aggregation. The anti-thrombotic and anti-platelet potential was evaluated, in this paper, with the BuOH soluble fraction of Angelica dahurica root. The BuOH fraction was divided into five subfractions fr. A - E and tested in the mouse model of thrombosis. Survival was enhanced to 35% with fr. A or fr. E treated (500 mg/Kg, p.o.) group of mice compared with 5% survival of the control group. However, none of the 8 coumarin glycosides obtained from fr. A, at the conc. of 0.5 mg/ml, showed inhibitory effects against rat platelet aggregation induced by ADP or collagen.

  • The aim of this study was to evaluate the anti-helicobacter activity and anti-inflammatory activity of Angelica dahurica (AD). The minimum inhibitory concentration(MIC) of AD against Helicobacter pylori(H. pylori), expression of the H. pylori cagA gene in the presence of AD was determined. Inhibition of H. pylori urease by AD, inhibition of nitric oxide (NO) production in AGS cells was measured. IL-8 mRNA expression in AGS cells which were infected with H. pylori and IL-8 level was measured. The MIC of MeOH Ex. of AD was $250{\mu}g/mL$ and the expression of cagA gene was decreased about 88% in the presence of AD. The activity of H. pylori urease was inhibited 70% by AD. mRNA expression of IL-8 and the production of NO and IL-8 were significantly decreased in the presence of AD. In conclusion, AD showed anti-Helicobacter activity and has potent anti-inflammatory effect on H. pylori-induced inflammation in human gastric epithelial AGS cells.

  • In the course of finding Korean natural products for acetylcholinesterase (AChE) inhibitory activity, we found that a methanolic extract of the roots of Angelica dahurica showed significant inhibitory effects on AChE. Bioassay-guided fractionation of the methanolic extract resulted in the isolation of three furanocoumarins, isoimperatorin (1), imperatorin (2) and oxypeucedanin (3), as active principles. These compounds inhibited AChE activity in a dosedependent manner, and the $IC_{50}$ values of compounds 1-3 were 74.6, 63.7 and 89.1 uM, respectively.

  • In our efforts to discover novel phytoestrogens to treat menopausal symptoms, eleven furanocoumarins were isolated from Angelica dahurica and tested for their estrogenic activity on the Ishikawa cell line. Among the compounds tested, 9-hydroxy-4-methoxypsoralen and alloisoimperatorin showed strong abilities to induce alkaline phosphatase (AP) with $EC_{50}$ values of 1.1 and $0.8\;{\mu}g/mL$, respectively, whereas the other nine furanocoumarins were weakly or only slightly active.

  • Ten coumarins were isolated from the root of Angelica dahurica by repeated silica gel column chromatography. Their chemical structures were elucidated on the basic of physicochemical and spectroscopic data. Among them, oxypeucedanin hydrate acetonide (7) was isolated for the first time from this plant. Cytotoxicity of coumarins isolated were determined in vitro against L1210, HL-60, K562, and B16F10 tumor cell lines by MTT method. Pangelin (5) and oxypeucedanin hydrate acetonide (7) showed a potent cytotoxic activity with the $IC_{50}$ values of 8.6 to 14.6 ${\mu}g$ /mL against four kinds of tumor cell lines. Other compounds showed the moderate cytotoxic activity or no activity against the tumor cell lines.

  • Five furanocoumarins including a new one were isolated from the root of Angelica dahurica by repeated silica gel column chromatography. Their chemical structures were determined to be isoimperatorin (1), oxypeucedanin hydrate-3"-butyl ether (2), imperatorin (3), knidilin (4), and oxypeucedanin hydrate (5). This represents the first study in which the compound 2 has been isolated and identified, The long-range coupling ($^{5}J$) in the $^1H$-NMR spectrum observed in the linear furanocoumarin skeleton was also investigated in detail.

  • From the roots of Angelica dahurica Bentham et Hooker (Umbelliferae), three known coumarin derivatives have been isolated and identified as 8-(2-hydroxy-3-methoxy-3-methylbutyloxy) psoralen, 5,8-di(2,3-dihydroxy-3-methylbutyloxy) psoralen, 9-[3-($\beta$-D-glucopyranosyloxy)-2-hydroxy-3-methylbutoxy]-7H-furo[3,2-g][1]benzopyran-7-one. This is the first report of the occurrence of these compounds in this plant. These three compounds were tested for activity in septic shock model. Among these compounds, 2 showed relatively strong preventive activity against septic shock.

  • This study was conducted to provide improvement measures for Korea's medicinal crop farmers whose business has been severely damaged by imported medicinal herbs. To accomplish this, the performance and efficiency of farming Angelica dahurica and Bupleurum falcatum were analyzed. The results of the analysis can be summarized as follows. First, the farming households cultivating Angelica dahurica had an average revenue of 1,363,000 KRW per 10 acres. The average income per 10 acres was 500,000 KRW, and the income ratio was 36.7%. Second, the farming households cultivating Bupleurum falcatum had an average revenue of 1,705,000 KRW per 10 acres, with an average income per 10 acres of 873,000 KRW and an income ratio of 44.6%. Third, the farming households cultivating Angelica dahurica were found to have a technical efficiency of 0.790, a pure technical efficiency of 0.856, and a scale efficiency of 0.924. Fourth, the farming households cultivating Bupleurum falcatum were found to have a technical efficiency of 0.670, a pure technical efficiency of 0.794, and a scale efficiency of 0.844. Both Angelica dahurica and Bupleurum falcatum farming households showed relative differences in technical efficiency. The pure technical aspects, rather than the scale aspects, were shown to contribute more to the differences.
