This study aimed to determine the photosynthesis and growth characteristics of Peucedanum japonicum T. grown under aquaponics in a plant factory (AP) by comparing those grown under hydroponic cultivation system (HP). The AP system raised 30 fishes at a density of 10.6 kg·m-3 in a 367.5 L tank, and at HP, nutrient solution was controlled with EC 1.3 dS·m-1 and pH 6.5. The pH level ranged from 4.0 to 7.1 for the AP system and 4.0 to 7.4 for the HP system. The pH level in the AP began to decrease with an increase in nitrate nitrogen (NO3-N) and lasted bellower than pH 5.5 for 15–67 DAT. It was found that ammonium nitrogen (NH4-N) continued to increase even under low pH conditions. EC was maintained at 1.3 to 1.5 dS·m-1 in both systems. The concentration of major mineral elements in the fish tank was higher than that of the hydroponics, except for K and Mg. There was no significant difference in the photosynthesis characteristics, but the PIABS parameters were 30.4% lower in the AP compared to the HP at the 34DAT and 12.0% lower at the 74DAT. There was no significant difference in the growth characteristics, but the petiole length was 56% longer in the leaf grown under the AP system. While there was no significant difference in the fresh and dry weights of leaf and root, the leaf area ratio was 36.43% higher in the AP system. All the integrated results suggest that aquaponics is a highly-sustainable farming to safely produce food by recycling agricultural by-products, and to produce Peucedanum japonicum as much as hydroponics under a proper fish density and pH level.

본 연구에서는 인공광 시설에서 광원을 달리하여 생산된 방풍나물의 항산화 및 항염 효과를 평가하였고 노지 재배 된 방풍나물과 그 생리활성을 비교하였다. DPPH 및 ABTS 라디칼 소거 활성 및 총 폴리페놀은 노지에서 재배 된 방풍나물이 인공광 시설에서 재배된 방풍나물보다 높은 항산화 활성을 나타내었고, 인공광에서 재배된 방풍나물 중 에서는 BW 광원으로 재배된 방풍나물이 농도 의존적으로 높은 항산화 효과를 보였다. XO 저해 활성은 BW 재배된 방풍나물이 노지 재배 방풍나물보다 우수한 효과를 나타내었다. SOD와 CAT 결과는 BW 및 노지 재배된 방풍나물 모두 무처리 대조군에 비해 농도 의존적인 활성을 보였다. BW 및 노지 재배된 방풍나물은 방풍나물을 처리하지 않은 무처리 대조군에 비해 TNF-α 와 IL-6 사이토카인을 농도 의존적으로 유의하게 감소시켰다. 따라서 인공광 재배 된 방풍나물은 대체적으로 노지보다 낮을 수 있지만 항산화 및 항염 효과를 보였고. 앞으로 인공광에서 재배된 작물의 다양한 기능성 소재로서의 연구에 도움이 될 것으로 기대된다.

Helicobacter (H.) pylori is one of the most common pathogenic bacteria in the human gut, and is also one of the most important factors that cause digestive disorders such as chronic inflammation, gastric ulcers, and even gastric cancer. Since the use of various antibiotics to treat H. pylori infection is associated with the development of resistance in this bacterium, the aim of this study was to determine the anti-H. pylori effects of Peucedanum japonicum extracts (PJE) in the stomach tissue of C57BL/6 mice. In this experimental study, 50 C57BL/6 mice in five groups were evaluated. After induction of H. pylori infection in mice with the standard strain of H. pylori (ATCC 43504), the infected mice were treated with 3 different doses of PJE in different groups. Then, the anti-H. pylori effects of PJE were evaluated by rapid urease test (CLO), histopathological exam and blood interleukin (IL)-8 ELISA analysis. Based on CLO results, H. pylori eradication effects of PJE was observed. H. pylori infection of C57BL/6 mice showed significant increase of histopathological lesion scores. However, the treatment of PJE showed significant decrease of histopathological lesion scores. The treatment of PJE decreased gastric inflammation and mucosal lesions in the stomach of H. pylori-infected mice. Blood IL-8 levels were elevated 4 weeks after H. pylori inoculation. However, the treatment of PJE showed significant decrease of IL-8 level. According to the results of this study, PJE could be useful in the reduction of H. pylori infection in the mouse model.

Background : Peucedanum japonicum Thunberg is herbaceous plant belonging to the umbelliferea. Its root is used as a herbal medicine. Recently, it is cultivated as one of the crops which are attracting attention as a new income crops by using leaf. It is cultivated as native variety and has no standard variety. As a first step to expand cultivation in Korea, we investigated growth characteristics of P. japonicum Thunberg which were collected from domestic regions to select standard variety for P. japonicum Thunberg. Methods and Results : From April in 2017 to June in 2018, total 245 individuals of Peucedanum japonicum Thunberg in forms of seedling from 24 locations including 7 Chungnam, 10 Gyeongbuk, 2 Jeonnam, 1 Gangwon and 4 Jeju were collected and 40 × 20 ㎝ intervals transplanted. In August 2018, the research was carried out on 4 qualitative traits such as stem color, peduncle color, and 11 qualitative traits such as plant height, leaf length, and leaf width based on the test guidelines. As a result, the 21 - 2 species collected in Jeju showed the best growth with 88.0 ㎝ plant height, 267 leaf number, and 174 peduncle number. A total of 245 collecting species were classified into 4 qualitative traits. The stem color was classified into green 125, red green 98, crimson green 21, and light green 1. The 114 species which were developed into flower were divided into green 94, red green 17, crimson green 2, and light green 1, and immature seed color was classified into green 88 and red green 26. The anthocyanin expression was excellent, and the total number of stem color, peduncle color, and immature seed color were 7 collecting species. The inflorescence type was classified into 54 semi-circular type, 47 straight type, 12 spread type. The 4 - 4 species collected in Taean were not registered in the test guidelines, and the compound umbel and cyme were appeared together. Conclusion : The growth characteristics show various differences among collection areas. It is considered that the superior lines can be selected as a standard variety breeding material by comparing the growth characteristics of the collected species.

Background : Glehnia littoralis F. and Peucedanum japonicum T. is mostly founded coastal region of Korea, Japan, Taiwan, and China. Recently, because interests of health functional food has been increased the role of miscellaneous medicinal crop is not only strengthen provided energy but also health functional role and many researchers showed interest in plants to in beauty treatment and functional healthy food. The objectives of this research was to analyse antioxidant activity of G. littoralis and P. japonicum. using various plant parts. Methods and Results : Different analysis including DPPH free radical scavenging activity, Total phenolic contents and Total flavonoid content were performed to evaluate the antioxidant activity of different plant part in G. littoralis and P. japonicum. DPPH free radical scavenging activity was calculated a RC50 value (㎍/㎖). Total phenolic contents and total flavonoid contents were expressed as milligrams of gallic acid and quercetin equivalent per gram of dry weight. Respectively, RC50 value of DPPH radical scavenging was higher (900.78 ± 87.53 ㎍ /㎖) in leave of P. japonicum and the lowest RC50 value of DPPH radical scavenging was observed (3806.74 ± 1361.38 ㎍/㎖) in root of G. littoralis. The highest total phenolic level was 5241.46 ± 228.52 ㎎․GAE/g and total flavonoid level was 426.11 ± 37.34 ㎎․QE/㎎ were detected in leaf of G. littoralis. Results showed that DPPH free radical scavenging activity, total phenolic contents and total flavonoid content were higher in leaf of G. littoralis and P. japonicum. Conclusion : Thus, medicinal plants can be an important resource for producing cosmetic and functional health food.

Background : The purpose of this study was to evaluate methods to high quality medicinal vegetables, thereby increasing farm income. This study investigated the effects of different green manures crop and application culture stable foliage production in Peucedanum japonicum Thunberg.
