Volatile flavor compounds Angelica gigas Nakai and Angelica acutiloba Kitagawa were extracted by SDE (simultaneous steam distillation & extraction) using the mixture of n-pentane and diethylether (1:1, v/v) as an extract solvent and analyzed by GC-FID and GC-MS. The amount of essential oils of top part and root in Angelica gigas were obtained in 0.063% (v/w) and 0.389% (v/w) yields as a fresh weight base, respectively. The main compounds in top parts and the root were identified as nonane (7.51% and 24.49%, respectively), ${\alpha}-pinene$ (14.64% and 31.75%), limonene+${\beta}-phellandrene$ (14.01% and 9.66%), ${\gamma}-terpinene$ (7.85% and 1.20%), germacrene-d (5.85% and 0.22%), (E,E)-${\alpha}-farnesene$ (6.05% and 1.40%), ${\beta}-eudesmol$ (5.26% and 1.84%). Although these compounds were present in both parts. The results showed large differences in. the concentrations of them much varied. The amount of essential oils stem and leaf obtained (0.068% and 0.127% in A. gigas) and (0.153% and 0.243% in A. acutiloba) yields as a fresh weight base, respectively. More than 18 and 32 components in stem and leaf have been identified, which of main components in A. gigas were ${\alpha}-pinene$, myrcene, limonene, germacrene-d, eudesmol and butylphthalide, but germacrene-d and butylphthalide contents were also different in stem and leaf. And more than 21 and 32 components in A. acutiloba were ${\gamma}-terpinene$ and butylphthalide. Volatile compounds were very different in both species.

This study was conducted to investigate the antioxidant effect of 80% ethanol extracts from Angelica acutiloba Kitagawa (A. acutiloba Kitagawa) in vitro. The extract was further fractionated subsequently by n-hexane, chloroform, ethylacetate, n-butanol and water. Antioxidative activities of different fractions were examined by 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical generation, Rancimat test, thiobarbituric acid (TBA) value, nitrite scavenging activity, inhibition of lipid peroxidation and peroxide value (POV) in linoleic acid in comparison with the commercial antioxidant butylated hydroxy toluene (BHT). Antioxidant activities of n-hexane fraction of Angelico acutiloba Kitagawa ethanol extract were the highest among fractions and were a little less than that of BHT. Nitrite scavenging activity showed the most remarkable effect at pH 12. These results suggest that ethanol extracts of A. acutiloba Kitagawa can be used in natural antioxidant source.

In genus Angelica, three species have been used and cultivated for medicinal material in orient, A. gigas in Korea, acutiloba in Japan and sinensis in China. A. gigas (Chamdangui) is different from A. acutiloba or A. sinensis in the contents chemical components and their efficacious. In Korea, in particular, A. acutiloba has been cultivated in a small acreage from several decades ago, and recently A. sinensis has been trying to cultivate. A trial of adaptation and cultivation of the three species was performed in different altitudinal regions such as Suwon (50 m of sea level), Jinbu (500 m of sea level) and Taebak (700 m of sea level). A. gigas and acutiloba grew and produced roots successfully at all locations, but A. sinensis could grow only at high altitudinal region, Taebaek. A. sinensis survived 70.3% at Taebaek, but only 45.2% at Jinbu and 3.6% at Suwon. The dry root yield of A. sinensis was as low as 1,600 kg/ha at Taebaek and 1,270 kg/ha at Jinbu comparing farmers' average root yield of A. gigas, 3,000 kg/ha however, no root could be harvested at Suwon. The results, showed it was that A. sinensis could not grow at low altitudinal plane area except high altitude area in Korea. Even though it could grow, the root yield was too low to support the income.

This study compared the major chemical components of Angelica gigas of Korea, A. acutiloba of Japan, and A. sinensis of China. A. gigas had the highest crude fat level, A. acutiloba the highest moisture content, and A. sinensis the greatest crude protein level. The main free sugar was fructose in three species. Total amino acid contents of A. gigas, A. acutiloba and A. sinensis were 4,178.64 mg%, 2,952.10 mg%, and 3,367.13 mg%, respectively. Although amino acid compositions of the three species were different, arginine, proline and lysine were the major amino acids in all species. The main saturated fatty acid was caproic acid in A. gigas and palmitic acid in A. acutiloba and A. sinensis. Linoleic acid, linolenic acid, and oleic acid were the main unsaturated fatty acid in all three species. Oxalic acid was the major organic acid in the three species. Vitamin A contents of A. gigas, A. acutiloba, and A. sinensis were 5.10 mg%, 6.32 mg%, and 6.11 mg%, respectively. However, vitamin E was detected only in A. gigas, at 0.47 mg%.. The mineral contents of the three species were (in order of concentration) K, Mg, Fe, and Na.

In June 2019, Angelica acutiloba plants showing virus-like symptoms such as chlorotic local lesion and mosaic on the leaves were found in a greenhouse in Nonsan, South Korea. To identify the causal virus, we collected 6 symptomatic A. acutiloba leaf samples and performed reverse transcription polymerase chain reaction (RT-PCR) analysis using specific detection primers for three reported viruses including tomato spotted wilt virus (TSWV). RT-PCR results showed that five symptomatic samples were positive for TSWV. Mechanical sap inoculation of one of the collected TSWV isolate (TSWV-NS-AG28) induced yellowing, chlorosis and mosaic symptoms in A. acutiloba and necrotic local lesions and mosaic in Solanaceae species. Phylogenetic analysis based on the complete genome sequences showed that TSWV-NS-AG28 had a maximum nucleotide identity with TSWVNS-BB20 isolated from butterbur in Nonsan, South Korea. To our knowledge, this is the first report of TSWV infection in A. acutiloba.

This research was performed to make functional papers by using the waste of herbal medicine such as Astragalus membranaceus, Angelica acutiloba, and Artemisia capillaris as additives, and to evaluate their physical and optical properties of the manufactured paper. The physical and optical properties were decreased with the increase of the amount of herbal medicine. Of those manufactured papers, the functional paper with Artemisia capillaris showed the dramatic decrease in its physical properties. Adding the herbal medicine waste as additives developed the aesthetic pattern on the surface of the manufactured paper. The paper showing the black pattern on white surface was most favored. Different patterns could be made by changing the size of fibers and the amount of wastes. There was odor emitted from the paper due to the herbal medicine waste, which make the paper to have a potential for the diverse purpose. The herbal medicine waste can be applied to replace weighting agents in the manufacturing process of paper or used for the fuctional additives, resulting in the reduce of the quantity of a pulp consumed. The paper with 10-20% Angelica acutiloba waste were thought to have the most excellent quality on the process point of view.

An analysis of RAPD-PCR (random amplified polymorphic DNA-polymerase chain reaction) was performed with three Angelica species (A. gigas Nakai, A. sinensis (Olive.) Diels and A. acutiloba Kitag) in an effort to distinguish between members of these three species. Two arbitrary primers (OPC02, OPD11) out of80 primers tested, produced 17 species-specific fragments among the three species. Eight fragments were specific for A. sinensis, four fragments specific for A. gigas, five specific for A. acutiloba. When primers OPC02 and OPD11 were used in the polymerase chain reaction, RAPD-PCR fragments that were specific for each of the three species were generated simultaneously. Primer OPC02 produced eight species-specific fragments: four were specific for A. sinensis, one for A. gigas, and three for A. acutiloba. Primer OPD11 produced nine speciesspecific fragments: four for A. sinensis, three for A. gigas, and two for A. acutiloba. The RAPD-PCR markers that were generated with these two primers should rapidly identify members of the three Angelica species. The consistency of the identifications made with these species-specific RAPD-PCR markers was demonstrated by the observation that each respective marker was generated from three accessions of each species, all with different origins. We also performed the RAPD-PCR analysis with the dried Angelica root samples that randomly collected from marketed and from the OPC02 primer, obtained a A. gigasspecific band and the band were cloned and sequenced.

Background: Angelica acutiloba Kitagawa belongs to the flowering plant family Apiaceae. Its young leaves are consumed as a vegetable, and its roots have medicinal properties. This study was conducted to analyze the seed germination characteristics of A. acutiloba according to its ripening stages. Methods and Results: The seeds were harvested from a research farm managed by the Department of Herbal Crop Research, Rural Development Administration in 2018 and were divided into six groups according to their specific gravities. In particular, we studied the effect of harvesting periods and umbel orders on seed characteristics. The results showed that the rates of germination, emergence, and early growth improved as the specific gravity of the seeds increased. In addition, the germination rates of the seeds harvested in mid July and early August were significantly higher than those harvested in the other seasons, and the seeds obtained from the first floret had the greatest mass and weight. Conclusions: In this study, we demonstrated that it is possible to improve the germination rate by appropriate selection of seeds and harvesting period both of which are closely related to seed maturity.
