Silica gel column chromatography on the ether extract from the fruits of Angelica koreana $M_{AXIMOWICZ}$ gave two kinds of crystalline products of coumarin. The following furocoumarins-imperatorin and bergapten has been identified by elemental analysis, IR, NMR spectra and physico-chemical tests.

To study the efficacy of extract powder of Angelica gigas in preventing and treating degeneration of the articular cartilage in rats with monosodium iodoacetate (MIA)-induced osteoarthritis, A total of 30 six-week-old Sprague-Dawley rats were randomly divided into normal control group, untreated group and Angelica gigas treated group, with 10 rats in each group. During the treatment period, body weight were measured in each four days interval from starting date. The rat were sacrificed at the end of 3rd week after daily administration of Angelica gigas and then rat tibia articular cartilage was removed. In articular cartilages, glycosaminoglycan (GAG) amount increased by MIA treatment were reduced while proteoglycan (PG) amount decreased by MIA treatment were fairly recovered by Angelica gigas treatment, respectively. The content of TNF-a was also slightly reduced sections of the cartilage were stained with safranin-0 were also partially recovered by Angelica gigas treatment. By HPLC analysis, the content of main compounds decursin and decursinol angelate was analyzed as $10.5{\pm}0.2%$ of total extracts.

In continuation of our studies on essential oils of Angelica genus(Umbelliferae), We report on the components of essential oils obtained from the root of Angelica tenuissima Nakai(藁子). Oils were 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. Essential oils of the root of A. tenuissima(Gaoben) were found to contain $\alpha-pinene,\;camphene,\;\beta-pinene,\;myrcene,\;\alpha-phellandrene,\;\Delta-3-carene,\;p-cymene,\;limonene,\;\gamma-terpinene,\;terpinolene,\;4-vinylguauacol,\;\gamma-elemene$, one aromatic compound, three unidentified sesquiterpene alcohols, butylidenephthalide, senkyunolide and Z-ligustilide which was the most abundant compound comprising 75% of the whole oil. Also butylphthalide and hydroxybutylidenephalide were tentatively identified.

The effects of various cooking methods (blanching, microwave heating, and deep-fat frying) on biologically active components of Angelica keiskei were determined by HPLC. Cynharoside, the biologically active component of Angelica keiskei leaves was 4.82%, which was rapidly decreased by blanching, showing 3.79%, 2.59% and 1.74% at 1 min, 2min and 3min, respectively. Microwave heating also decreased the cynaroside contents slowly by 2 min and rapidly by 3min, respectively. Microwave heating also decreased the cynaroside contents slowly by 2min and rapidly by 3 min, showing 4.25% at 1 min, 3.38% at 2 min, and 1.49% at 3 min. Among the cooking methods tested, deep-fat frying was shown to preserve the cynaroside most. Only 3.90% of cynaroside was lost by 5 min frying. The decrease in cynaroside in each cooking method was supposed to be due to the conversion of cynarside, a glycoside of flavonoid, into luteolin through lysis of glucose at C-7 position on cynaroside.

It was revaluated about taxonomical position of the Tilingia tsusimensis (Yabe) Kitagawa (Apiaceae) collected from Mt. Gaya, Mt. Geumo, and Mt. Songni in Korea. Its diagnostic features include slightly dorsally compressed mericarps, acute-prominent ribs, ternate leaves, and dimorphic white petals. It is morphologically similar to Cymopterus and Pimpinella in having ternate leaves. It is distinguished from Cymopterus having asymmerty mericarps, 3-4 mericarp ribs, and winged dorsal ribs. Pimpinella differs in having slightly laterally compressed mericarps without ribs and conspicuous calyx teeth. Also, it looks like Angelica with obsolete calyx teeth and multilayer pericarps, but is distinguished by having its broadly winged lateral ribs and strongly dorsally compressed mericarps. Tilingia tsusimensis formed a monophyletic clade or sister group relationship with a genus Angelica based on ITS sequences. Based on the above observations, we conclude that this plant is here referred to T. tsusimensis (Yabe) Kitagawa.

Changes in the contents of volatiles and chlorphylls of Angelica keiskei Kimchi during fermentation were investigated. Total chlorphyll contents decreased gradually during the fermentatin period. Chlorphyll a decreased rapidly from 1.38 to 0.5$\mu\textrm{g}$/cm by the 5th day of fermentation with no further changes at 7th day, while chlorophyll b did not show any change by 3rd day and decomposed rapidly thereafter. Major voltile compounds identified in the kimchi were sabinene, $\alpha$-pinene and $\alpha$-terpinolene, which were gradually decreased during fermentation. There were significant differnce in color, sourness, bitterness and overall acceptability in sernsory evauation of Angelica keiskei Kimchi during fermentation at 2$0^{\circ}C$.

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.

A comparative study on 'Dang-gui' and 'Kang-whal' the two species of Angelica growing in Korea was carried out about the morphology and cytology. The somatic chromosome number of Cham dang-gui, Ill dang-gui, Badi-namul was found to be 2N=22. The somatic chromosome number of Kang-whal was found to be 2N=110, that of Chili kang-whal to be 2N=44, that of Mul kang-whal to be 2N=22. Stoma of species of Dang-gui were same in size. Those of Chili kang-whal and Kang-whal were strikingly larger than the other. Chili kang-whal and Kang-whal were verified to be polyploid in the genus Angelica.
