DNA 바코드를 기반으로 하여 외국발 국내 입항 선박에서 검출되는 편승자 해충(hitchhiker insect pests)에 대한 모니터링을 수행하였다. 국내 입항 선박 조사는 2018년 6월 1일부터 2018년 9월 17일까지 약 109일간 111개 선박에 대해 실시하였다. 모니터링 대상 해충은 ‘보고잡기법(simply collecting method by hands)’으로 확보하였으며, 총 336개체에 대해 종동정을 실시하였으며, 이를 통해 확보된 정보들은 선박정보(선박명, 선박번호, 출항지, 입항지), 조사정보(조 사일, 채집시 표본 상태, 조사자), 유전자 분석 정보(프라이머 정보, 서열판독 결과), 분자생물학적 종동정 정보(NCBI GenBank Accession No., NCBI Blast Searching Results, BOLD Identification Request), 분류학적 통합종 확증 정보(목명, 과명, 종명, 동정자, 비고) 등으로 구분하였으며, MS-Excel을 이용하여 각 필드값에 맞게 기초정보를 입력하였다. 이를 기반으로 하여 편승자 해충에 대한 선박 경로에 따른 편승 양상뿐만 아니라, 월별, 분류군별, 미서식종별로 편승 양상을 분석하였다. 그 결과, 편승사례는 선박 경로에 따라서는 중국에서 출항하거나 중국을 거쳐 편승하는 사례가 207건, 월별로는 9월이 134건, 분류군별로는 나비목이 208건으로 가장 많았다. 특히, 미서식종별 편승 양상에서 는 총 3목 9과 13종 21개체가 국내 입항 선박에서 검출된 것으로 나타났으며, 이 중 2목 6과 9종 15개체는 살아있는 상태로 채집된 것을 확인되었다. 이와 같은 결과로 볼 때, 앞으로 더욱 많은 정보가 확보된다면, 현재의 통계 분석 방법은 편승자 해충의 모니터링뿐만 아니라 대상 해충의 위험성 평가 및 검역검사에 매우 효율적인 정보를 제공할 수 있을 것으로 사료된다.

Background : Aralia continentalis Kitag. (syn. = A. cordata Thunb., Araliaceae) is a traditional medicinal herb spread widely in northeastern Asia, including Korea, China, and Japan. Many constituents from its root extracts, including diterpene and essential oils, have been isolated as active components for antioxidant, anti-inflammatory, analgesic, sedative, antifungal, anti-thrombotic, and growth inhibition. In this study, we describe the structural determination of the two new compounds. Materials and Results : The roots of A. continentalis were collected in Namwon-si, Jeollabuk-do, Korea, in March 2018 and identified by one of the authors (Dr. S. S. Hong). The roots of A. continentalis were extracted with 70% EtOH two times at room temperature. The concentrated residue was subsequently suspended in H2O and partitioned with n-hexane, CH2Cl2, EtOAc and n-BuOH. The n-hexane, CH2Cl2, and EtOAc layer were subjected to sequential column chromatography over silica-gel, RP-18, MPLC and preparative HPLC to isolated the compounds 1 - 30. Consequently, a new nor-ent-pimaran diterpenoid (11) and a new 8-O-4′ type neolignan (25) along with 28 known compounds that included diterpenoids, phenolic derivates, and polyacetylenes have been isolated from the ethanol extract of the roots of A. continentalis. The structures of the new compounds were established by spectroscopic data interpretation, particularly HRESIMS, 1D and 2D NMR data including HSQC and HMBC. Also, those of the known compounds were identified by spectral comparison with those of the reported values. Conclusion : The structures of two new compounds were determined as 18-nor-ent-pimara-9 (11),15-diene-4β-ol (11) and 8-O-4-dehydrocoumaroyl-ferulic acid (25). To our knowledge, compounds 10, 14, 15, 19, 20, 22 – 24, and 26 were isolated and identified from Aralia genus for the first time.

Background : Recently, with the growth of traditional medicine industry, management of the quality of herbal medications as a raw material for functional food and medicine becomes more important. One of the most difficult problems of quality control of medicinal plants is management in storage insects. The problem of storage insects is a matter that must be resolved in order to safely obtain raw materials in herbal sector. But the basic prevention measures as well as grasp of the exact situation in the field are not yet. In this study, we investigated to see the problems and solutions through a review of storage pest management system of medicinal plants and the relevant provisions in herbal sector. Methods and Results : For this study, we examined the Status of domestic distribution, storage pest control techniques, news, domestic and import regulations. Storage pests that occur in herbal medications have dropped commercial value and it leads to consumer mistrust. A report said that consumers who had found at least once a pest and microbial contamination when they buy a herbal medications is more than 50% (2004, Ministry of Food and Drug Safety). In the past, those who want to solve these problems had tried through the sulfur fumigation. However, due to concerns about the risk to humans nowadays it was banned in many countries. According to the latest editions of Korean Pharmacopoeia (KP), it is allowed to use a suitable fumigant. but the domestic and imported medicinal plants during distribution can not be used it. Because currently registered fumigant (aluminium phosphide) is allowed only imported medicinal plants in the quarantine process. Chemical fumigation is inappropriate for use in foods and pharmaceuticals so the introduction of eco-friendly control methods is urgent. Eco-friendly methods of pest control that is currently being developed include a cold storage, packaging, high temperature and frozen method etc. Conclusion : These methods should be considered potential cost and Feasibility and it should meet the condition that stated “"Do not change the therapeutic effects of the herbal medications.” in the KP. Also supporting policy for expanding low temperature storage facilities in distribution area will raise possibility of success.

Background : Most of cases in korea, distributed herbal medications are storaged in room temperature and it causes many insect pests during storage. Despite the fact, there is little research about storage conditions. Temperature and humidity in storehouse are highly related with pests’ overwintering, generation length and the number of occurrence in summer. Consequently, in this research, major pests’ overwintering was studied by reviewing facility condition, temperature and humidity in major regional storehouses. The results of this would help to develop how to manage pest occurrence in distributed herbal medications. Methods and Results : For this study, storage facilities was investigated at different regions including Gyeongdong Market in Seoul, the pharmaceutical company in Daegu and farmhouse in Youngcheon by monitering temperature, humidity, ventilator, air conditioning and heating on ground and underground places from June 2014 to July 2016. including Upon investigation, most of building using for storage had simple ventilators. Whereas in case of farmhouse, it is vulnerable to maintaining quality. Because most farmhouse had temporary buildings which are difficult to control temperature and humidity. In addition, among the other surveyed warehouses, Basement in the Gyeongdong Market had most favorable condition for pest overwintering. The lowest temperature of it was seldom below zero maintaining level of about 1.5℃ and average temperature was about 10℃ in underground warehouse during winter. And the ground warehouse of Daegu had similar patterns in temperature and humidity with that of Seoul in that being over 0℃ even in the winter. In Youngcheon, the temperature of farmhouse was below zero degree and the daily range of temperature and humidity was wide. It caused difficulty of overwintering of insect pests but possible to inhabit. Conclusion : According to a study by Han-Mo, Koo(1997), it was impossible to overwinter for Lasioderma serricorne F. which is dominant medicinal plants’ pest in north of the Chungcheong region’s warehouse due to low temperature. But in case of investigated warehouses, it was possible to overwinter because of the high temperature in office building or basement storage area. In order to make prediction of pest occurrence and comprehensive measures, it is urgent to take more investigation by regional groups and types of storage.

Background : The objective of this study was to Amomum tsao-ko Crevost et Lemarié, (Zingiberaceae) is widely distributed among several countries in South Asia and Southeast Asia. It is a well known spice in Asia, produces a nice refreshing effect in the mouth. Additionally, it's dried fruit is used in Traditional Chinese Medicine (TCM) for cardiac diseases, edema, eye trouble, skin, itch and impotence. The objective of this study was evaluated the inhibitory activity on adipogenesis in 3T3-L1 cells from A. tsao-ko. Methods and Results : The fruits of A. tsao-ko were extracted with 80% EtOH two times at room temperature. The EtOH extract was suspended in distilled water and partitioned with solvent to give CH2Cl2, EtOAc and n-BuOH. The CH2Cl2 was suspended in n-hexane and partitioned with solvent to give 50%, 70% and 90% MeOH. The purification of each fraction by column chromatography separation and HPLC analysis. Consequently, several constituents were isolated five known compounds. The identification and structural elucidation of compounds were established by using NMR (1D and 2D) and mass spectrometry. Conclusion : These compounds were identified as fluorenone (1), phenanthrene (2), anthracene (3), methyl linolenate (4), 1,2-benzenediol (5). All isolates were tested for their inhibitory activities on adipogenesis in 3T3-L1 cells.
