probiotics strains promoting the health are a collection of microorganisms that improve or restore microbial populations in the intestines. In this study, Leuconostoc probiotics was isolated from fermented gimchi and identified. Angelica dahurica, containing abundantly antioxidant activity, imperator, is a wildly grown species of angelica native. Before fermentation, total phenolics compound were 48.83 ± 4.9 GAE mg /g in the Angelica dahurica extract. After fermentation total phenolic compounds were 97.7 ± 12.6 GAE mg/g. The total amount of phenol in the fermented product was 30.2% higher than that before fermentation. The total flavonoid content before fermentation was 9.86 ± 4.3 mg / g and the total flavonoid content was 37.17 ± 7.4 mg/g after fermentation, which was 82.3% higher than before fermentation. The DPPH radical scavenging activity, superoxide radical scavenging activity, hydroxy radical scavenging activity and Fe++ chelating antioxidative activity of the Angelica dahurica extract were 41.6 ± 7.1%, 65.7 ± 8.4%, 55.26 ± 9.4% and 17.5 ± 4.6%, respectively. After fermentation, they were 60.3 ± 12.6%, 78.8 ± 8.3%, 56.9 ± 4.9% and 36.6 ± 8.9%, respectively. Therefore, the present study suggests that the fermentation using the probiotics strain of the Angelica dahurica extract can be used as a functional health food and cosmetic material with increased antioxidant capacity.
Background : Angelica dahurica, Ligusticum sinense and Ledebouriella seseloides are cultivated in small areas in Korea. Domestic cultivation area is around 10 ha, and cultivated varieties have not been developed yet. Therefore, the quality of the product is not uniform, and industrialization is difficult. Lately, studies on the development of varieties have been carried out using domestic collecting germplasm.
Methods and Results : Germplasm was collected in Gangwon-do, Chungcheongbuk-do, Gyeongsangbuk-do, Jeollanam-do and Jeju-do and sowed in pots in March 2017. Angelica dahurica was used the collected in Gyeongsangbuk-do, Jeollanam-do, Ligusticum sinense was used the collected in Gangwon-do and Gyeongbuk-do and Ledebouriella seseloides was used the collected Jeju-do. In May of 2017, those were planted and the stem and leaf characteristics were compared and analyzed 1-year. It was bloomed in the second years of 2018, and stem, leaf and flowering characteristics were compared and analyzed. In the first year of growth characteristics, Angelica dahurica showed lower leaf and stem growth in Jeollanam-do collected germplasm. However, there was no statistical significance. Growth characteristics of Ligusticum sinense were higher in Gangwon-do collection than in Gyeongsangbuk-do, but there was no statistical significance. Ledebouriella seseloides was no significant difference between the groups in Jeju-do. In the second years, individual selection were carried out for popullation improvement. The Angelica dahurica showed green and purple stalks and the collected germplasm of Jeollanam-do showed relatively low growth. Ligusticum sinense and Ledebouriella seseloides were no significant differences in growth and color between stem and leaf, stem and stem
Conclusion : All three crops were cross pollination, and collected open pollination. Therefore, there were many segregation by germplasm and genetic variation was large. Furthermore, it is considered that statistical significance does not appear. If genetic uniformity is increased through continuous selection and population improvement, it will be possible to cultivate varieties using germplasm. Genetic variation will be a good source of genetic resources.
Background : Angelica dahurica is the dried root of Angelica dahurica Bentham et Hooker f., a perennial plant belonging to the Umbelliferae family. Since its peak at 63 hectares in 2000, the cultivated area of Angelica dahurica dropped to its lowest level at 14 hectares in 2014 although there had been a short bounce back to 59 hectares in 2007. The decrease in the cultivated area has created a vicious cycle where even a small change in production amounts causes Angelica dahurica prices to fluctuate, leading farmers to become reluctant to cultivate the species. Therefore, this study aims to provide growers with new information on Angelica dahurica cultivation technology development, based on surveys and analyses of the difficulties and needs the farmers have. Methods and Results : Setting the nationwide Angelica dahurica farming households as the population, this study looked into 11 households of growers from main producing areas including Yeongju, Yeongcheon, and Bonghwa. Researchers carried out the survey by visiting the farmers and conducting face-to-face interviews using a prepared questionnaire. The survey was conducted for 2 months (from July to August 2016) to identify difficulties and specific characteristics of farming Angelica dahurica. SAS 9.2 was used for the statistical analysis. Conclusion : The surveyed types of difficulties identified were varieties, seeding, fertilization, pests, water management, weeding, soil, and drying. The results indicate that seeding (2.2) is the most serious difficulty, and water management (2.5), weeding (3.1), fertilization (3.7), pests (3.9) and others followed. Regarding specific technical problems, browning roots in the process of drying (61.5%) was the biggest concern along with germination after seeding (23.1%) and water management in the fields (15.4%). In response to the question about their willingness to expand farming in the future, no households showed intentions of expansion, while 36.4% reported intentions to reduce and 63.6% to maintain their current Angelica dahurica cultivation. The causes of weakening supply include low prices (54.5%), unreasonable pricing (36.4%), and difficulties in selling due to lack of retailers. Therefore, it seems necessary for the government to support sustainable Angelica dahurica farming by taking measures such as contract farming with herbal medicine circles, a minimum production cost guarantee system, or joint purchasing by the Agricultural Cooperative Association.
Background : Angelica dahurica Bentham et Hooker, Angelica gigas Nakai, Ostericum koreanum Maximowicz and Peucedanum japonicum Thumberg are a major medicinal plant in north Geungbuk province. Using medicinal plants are impotant it`s ingredient. Dry condition and stroage method are not standard manual. The ingredient variation of dry condition and stroage method were not researched. Methods and Results : Using plant material were cutivated on Gyongsangbukdo Bonghwa area. It were studied ingredient variation after dry and storage condition by HPLC methods. Major ingredient of Angelica gigas Nakai are decurusin, decurusinangelate. Heated air bulk dry get more decursin than natuarl dry and decurusinangelate of natural bulk dry was higher than heated air bulk dry. Major ingredient of Ostericum koreanum Maximowicz are imperatorin and isoimperatorin.. Imperatorin of Ostericum koreanum was highest peak on 50℃ heated-air dry after plastic bag sorage and isoimperatorin was highest peak on 40℃ heated-air dry after mountain cultivation. Imperatorin is a major ingredient Angelica dahurica Bentham et Hooker. Heated air bulk dry get more decursin and decursinangelate than natuarl dry and small heated-air dry. Peucedanol-7o_glucoside is a major ingredient Peucedanum japonicum Thumberg. Natural bulk dry get more peucedanol-7o_glucoside than heated-air bulk dry. Conclusion : Ingredient of Angelica dahurica Bentham et Hooker, Angelica gigas Nakai, Ostericum koreanum Maximowicz are different under various cutivation, drying method, storage. Diffent Ingedients of Angelica gigas Nakai, Ostericum koreanum Maximowicz were not accord it’s optical conditon.
