This study was conducted to determine feasibility of utilization of Angelica acutiloba. Especially, the quality characteristics of bread prepared with the addition of Angelica acutiloba powder were investigated. Sensory evaluation and spoilage test were conducted for preparation of functional breads which added with ground plant matters (leaves and stems) from Angelica acutiloba. The result showed that the functional breads had high score of overall liking as well as low spoilage rate when added with 0.5 to 1.0% ground plant matters of Angelica acutiloba. Consumer acceptability evaluation showed a significant preference when added 0.5 to 1.0% ground leaves and stems of Angelica acutiloba into breads. Functional breads which added powder of Angelica acutiloba inhibited the growth of fungi. The more addition of Angelica acutiloba powder, the higher the degrees of this inhibited. These results suggested that the shelf-lives of the breads were extended by the addition of Angelica acutiloba powder. Further studies were required for improvement of functionality and diversity of bread products using medicinal plant materials as an additive.

Root extracts of Angelica gigas and A. acutiloba have been used traditionally for the treatment of gynecological diseases, as well as anemia, blood stasis, and inflammatory pain, as blood tonics in Oriental medicine. In the present study, we investigated the effects of A. gigas and A. acutiloba on inflammatory mediators in mouse macrophages and compared their activities. Many studies suggest that prostaglandin $E_2$ ($PGE_2$) biosynthesis and nitric oxide (NO) production play important roles in the processes of both inflammation and carcinogenesis. Ethanolic extracts from the roots of both species exhibited significant inhibitory effects on $PGE_2$ generation in lipopolysaccharide-stimulated RAW 264.7 cells. In particular, the extract from A. gigas was more effective than that from A. acutiloba. Although neither inhibited NO generation, the extract from A. acutiloba stimulated NO generation. Our results suggest that the roots of A. gigas might possess more anti-inflammatory and/or cancer chemopreventative activity than that of A. acutiloba due to the suppression of cyclooxygenase-2 (COX2)-mediated $PGE_2$ production. In addition, A. acutiloba might exert anti-tumor activity through an increase in macrophage-produced NO.

This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10％, while germination rate of seeds collected in 2004 was above 90％. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4 ${\times}$ 4 ${\times}$ 5cm(length ${\times}$ width ${\times}$ height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

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.

Backgrounds: Danggui, one of the major herbs in Korean traditional medicine consists of three species: Angelica gigas of Korea, Angelica sinensis of China, and Angelica acutiloba of Japan. Despite its importance in Korean traditional medicine, recognition of the clinical differences between its three species is insufficient. Objectives: The purpose of the present review is to suggest evidence in using Angelica gigas, Angelica sinensis, and Angelica acutiloba distinctively in clinic, by comparing their pharmacological effects and bioactive compounds. Methods: We searched articles published from 2000 to 2009 in Pubmed, EMbase, and RISS. The search keywords were "Angelica gigas", "Angelica sinensis", "Angelica acutiloba", "dongquei", "toki", "Angelicae Radix", "Archangelica officinalis Hoffm.", "Garden Angelica", "Chinese angelica root", "tangkuei", and "danggui". 861 articles were searched. Among them, we selected 143 articles which met our inclusion criteria. Results: This review summarizes active constituents, experimental studies, clinical studies, pharmacokinetics, side effects and toxicity, drug interaction, and industrial use of Angelica gigas, Angelica sinensis, and Angelica acutiloba. Conclusions: While Angelica sinensis and Angelica acutiloba are relatively similar, Angelica gigas is quite different from the others in main active constituents and genetic form. The main experimental studies of Danggui are cardiovascular studies, central nervous system studies and anti-cancer activity. Even though there were cases in which the three species show similar pharmacological effects, the mechanism was not always shared. Therefore, distinguished use of Angelica gigas, Angelica sinensis and Angelica acutiloba is needed.

Angelica acutiloba is one of the most intensively cultivated medicinal plants in Korea. The roots of this plant have been used as an important herbal drug, especially for the treatment of various female disorders, as the traditional therapy in Korea and other Asian countries. Consumption of its fresh leaves as a healthy vegetable has recently increased. In this study, essential oil fractions were extracted from the roots and leaves of this plant by steam distillation. Compositions of the two oils were compared by gas chromatography-mass spectrometry (GC-MS). The antibacterial activities of the essential oil were determined against three strains of Escherichia coli. DPPH radical scavenging and reducing power tests were performed to evaluateits antioxidant activities. The cytotoxic activities of the essential oil against a human breast and a uterine cancer cell line were estimated by MTT tests. Additionally, the morphological changes after treatment of the oil fraction were observed under a microscope. The essential oil fraction and its main components, Z-ligustilide and butylidene phthalide, inhibited the growth of three E. coli strains examined, with minimum inhibiting concentrations (MICs) ranging from 1.0 mg/ml to 8.0 mg/ml. Additionally, the essential oil fraction of A. acutiloba exhibited significant DPPH free radical scavenging activity and reducing power. Significant cytotoxic activities of the A. acutiloba essential oil were observed for human uterine (Hela) and breast (MCF-7) cancer cell lines.
