The effects of aqueous extract and volatile substances of 2 Angelica plants on seed germination and seedling growth were investigated. The seed germination of Angelica gigas showed increase in proportion to increase in aqueous extract concentration of A. gigas, while that of Angelica acutiloba was reduced proportionally to the extract concentration. The seed germination of A. gigas and A. acutiloba treated with aqueous extract of A. acutiloba was inhibited. The seedling elongation of A. gigas and A. acutiloba was slightly increased at lower concentration of aqueous extract of A. gigas, whereas it was proportionally decreased at higher concentrations. The seedling elongation of 2 Angelica plants was decreased by the aqueous extract of A. acutiloba. The aqueous extract of A. acutiloba caused significant inhibition in seedling growth of 2 Angelica plants. The seed germination of Lactuca sativa was not affected by volatile substances emitted from 2 Angelica plants. The radicle elongation of L. sativa treated with volatile substances of 2 Angelica plants was inhibited slightly and it was not suppressed according to the concentration of volatile substances.

Eight species of the genus Angelica in Korea were examined for the activity of affecting drug metabolism and for the presence of coumarins. The results showed that various parts, especially roots and fruits of Angelica plants had strong effects on drug metabolism and that they contained various derivatives of coumarins.

During a disease survey in October 2019, leaf spot symptoms with a yellow halo were observed on Korean angelica (Anglica gigas) plants grown in fields in Pyeongchang, Gangwon Province, Korea. Incidence of diseased leaves of the plants in the investigated fields ranged from 10% to 60%. Morphological and cultural characteristics of two single-spore isolates from the leaf lesions indicated that they belonged to the genus Didymella. Molecular phylogenetic analyses using combined sequences of LSU, ITS, TUB2, and RPB2 regions showed distinct clustering of the isolates from other Didymella species. In addition, the morphological and cultural characteristics of the isolates were somewhat different from those of closely related Didymella spp. Therefore, the novelty of the isolates was proved based on the investigations. Pathogenicity of the novel Didymella species isolates was confirmed on leaves of Korean angelica plants via artificial inoculation. This study reveals that Didymella gigantis sp. nov. causes leaf spot in Korean angelica.

The internal structures of "Chunho", "Kangwhal" and "Dangui" and their original plants had been compared with each other in the prior report. Coumarin derivatives, khellactone from the roots of Angelica purpuraefolia $C_{HUNG}$ and decursin and decursinol from A. gigas $N_{AKAI}$ were also isolated. In this report, we made a simple and convenient identification method for the powdered drugs of several Angelica genus by using a thin layer chromatogrophic technique. The ehter extract of the powdered drugs were applied to a silica gel plate, and was developed with n-hexane and ethyl acetate (1:1) mixture. The characteristic U.V. absorption patterns of each drug were shown.

Antioxidant activity of Astragalus membranaceus, Polygonatum stenophyllum, Angelica gigas, Acanthopanax sessiliflorus and Angelica pubescens extracts cultivated in Jecheon prepared with different solvents were determined by 1,1-diphenyl-2-picrylhydrzyl(DPPH) radical scarvenging ability and thiocyanate method . The highest hydroxy radical scarvenging activity was shown in Acanthopanax sessiliflorus, while the lowest was in Polygonatum stenophyllum. Angelica gigas showed strong antioxidant activity by thiocyanate method. Methanol extracts and water extracts showed higher antioxidant activities than ethanol extracts. Angelica pubescens showed the highest polyphenol contents and Acanthopanax sessiliflorus showed the highest flavonoid contents. Direct correlation between the hydroxy radical scavenging activity and polyphenol contents or flavonoid contents was established by simple regression(r>0.8) in each solvent extracts. Among medicinal plants cultivated in Jecheon, Acanthopanax sessiliflorus and Angelica pubescens showed strong antioxidant activities. These results suggest that methanol or water extracts of several medicinal plant cultivated in Jecheon could be used as natural antioxidants.

The proximate composition of 3 kinds of Umbelliferaeceae Wild Plants (Angelica gigas NAKAI., Ostericum sieboldii NAKAI. and Coriandrum sativum LINNAEUS) were analyzed and used for making pork sausages as a functional ingredient. In the proximate composition, crude protein content was the highest in Ostericum sieboldii, 37.87%, and crude lipid and crude ash contents were the highest in Coriandrum sativum. Vitamin C was contained in Angelica gigas at 0.30mg%. but was not detected in Ostericum sieboldii and Coriandrum sativum. $\beta$-carotene content in Angelica gigas was the highest at 19.96%, but selenium was not detected in any of them. Total phenol content in Coriandrum sativum was the highest as 1107.43mg%. TBA and VBN values of all sausages with wild plants increased gradually during four-week-storage and were lower than those of control. Coriandrum sativum-added sausage had the lowest TBA as well as VBN valuew. During the four-week-storage at 4$\^{C}$, TBA value and VBN value were in the very safe range at all sample. Total phenol contents in sausages appeared to have more antioxidative activity than vitamin C, $\beta$-carotene and selenium, and consequently decreased the TBA values of sausages.

The anti-inflammatory effect of the methanolic extracts of some medicinal plants was investigated on the hydrolysis of N-benzoylarginine-p-nitroanilide by trypsin in vitro, the writhing syndrome induced by acetic acid in mice, and the carrageenin-induced paw edema in rats. Among tested medicinal plants, the methanoilc extract of Angelica keiskei, Rosa rugosa and Cudrania tricuspidata showed significant inhibitory effect. And we also found that adenosine, isolated from A. keiskei was identified as one active components.

This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were $\alpha$-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.

During disease surveys of Angelica acutiloba plants in Korea, leaf spot symptoms were observed in a field in Andong in July 2019, and stem rot symptoms in vinyl greenhouses in Yangpyeong in April 2020. Incidence of leaf spot and stem rot of the plants ranged from 10 to 20% and 5 to 30%, respectively. Morphological and cultural characteristics of fungal isolates from the leaf spot and stem rot symptoms fitted into those of the genus Phoma. Molecular phylogenetic analyses of two single-spore isolates from the symptoms using concatenated sequences of LSU, ITS, TUB2, and RPB2 genes authenticated an independent cluster from other Didymella (anamorph: Phoma) species. Moreover, the isolates showed different morphological and cultural characteristics in comparison to closely related Didymella species. These discoveries confirmed the novelty of the isolates. Pathogenicity of the novel Didymella species isolates was substantiated on leaves and stems of A. acutiloba through artificial inoculation. Thus, this study reveals that Didymella acutilobae sp. nov. causes leaf spot and stem rot in Angelica acutiloba.
