Angelica dahurica (Umbelliferae) grows in China, Japan, Russia, and Korea. The root of Angelica dahurica has been used as a traditional folk medicine to treat headache and toothache. In this study, the effects of the aqueous extract of Angelica dahurica on acetic acid-induced abdominal pain, carrageenan-induced edema, and thermal hyperalgesia were investigated using mice and rats. The present results showed that the aqueous extract of Angelica dahurica inhibited acetic acidinduced abdominal pain in mice and reduced carrageen-induced edema in rats. The present study showed that the aqueous extract of Angelica dahurica possesses anti-inflammatory and analgesic effects.

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.

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.

Objectives : This research was observed by examining the external and internal parts and the quantity of the surface components of the wild type and cultivar of Angelica dahurica in korea. Methods : The slice of the tested material mede by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by the microscope and examined the quantity of the surface components. Results : In the shape of the roots, the wild type had a very thin main root and 2 long roots, while the cultivar had a long root branched out from the short and thick main root making a square pyramid shape. Isoimperatorin was detected at Rt $17{\sim}18$ minutes. The wild type contained 0.56% while the cultivar contained it of 0.355%, thus the component of the wild type was about 1.5 times of that of the cultivar. Conclusions : It was thought that there might be also some differences in their genetic characteristics, etc.

Three coumarin derivatives, which stimulate collagen biosynthesis in human fibroblasts were isolated from Angelica dahurica root which has been used in traditional medicine for cold, headache, discharging blood and women's diseases. Three coumarin derivatives were identified as 5-benzofuranacrylic acid, $6,7-dihydroxy-4-(3-methyl-2-butenyl)-{\delta}-lactone\;(prangenidin)$, 5-benzofuranacrylic acid, $6,7-dihydroxy-4-methoxy-{\delta}-lactone\;(8-hydroxybergapten)$ and 5-benzofuranacrylic acid, 8-hydroxypsoralen(xanthotoxol) from their spectral data.

In this study, we analyzed and quantified the amounts of bioactive phenolic constituents, xanthotoxin (1), oxypeucedanin (2), and imperatorin (3) in each part of the root of Angelica dahurica by HPLC, which validated by ICH guide lines comparing the linearity, intra day precision, inter-day precision. As a result, the amount of imperatorin 2.96% in the rootlet was two fold higher than that of the main root 1.32%. On the other hand, the amounts of xanthotoxin and oxypeucedanin in the rootlet showed similar to those of main root. In addition, the cortex of root is more plentiful of three consitituents (0.66%, 0.53%, and 1.85%) than those of xylem (0.29%, 0.05%, and 0.07%). These results show that the rootlet and cortex contain a large amount of bioactive phenolic constituent including xanthotoxin, oxypeucedanin, and imperatorin than other parts of the root.

Skin aging is not a disease nor an abnormal phenomenon but a collection of degenerative changes with age, characterized by skin dryness, wrinkle formation, and loss of skin elasticity. The skin wrinkles are caused by either genetically predisposed factors or environmental factors such as UV irradiation or physical/chemical stimulus. The histological manifestations of wrinkles are changes in both amount and integrity of elastic and collagen fibers. Here we report the isolation and characterization of 3 active compounds, prangenidin, 8-hydroxybergapten, and xanthotoxol from Angelica dahurica root. The anti-wrinkle activities of these compounds were also investigated.

Essential oil of the root of Angelica dahurica Benth et Hook(Umbelliferae) was investigated. Essential oil was obtained from the dried roots by steam distillation and fractionated by column chromatography. Each isolate or fraction was identified by GC, GC-MS and spectral analysis. It was found to contain eleven monoterpenes such as ${\alpha}-pinene(4.74%),\;campben, {\beta}-pinene,\;myrcene,\;{\alpha}-phellandrene,\;{\delta}-3-carene(39.4%),\;{\alpha}-terpinene,\;{\rho}-cymene,\;{\beta}-phellandrene,\;{\alpha}-terpinene,\;terpinolene\;and\;also\;found\;to\;contain\;4-vinylguaiacol,\;iso-elemicin,\;{\beta}-elemene$, caryophyllene, ligustilide, osthol and seven tentatively identified sesquiterpenes.
