본 연구는 하천유역의 중금속을 제거하는데 식물을 활용하기 위해 1994년 7월부터 10월까지 전라북도에 위치한 전주천과 그 주변하천에서 7개 지점을 선정하여 토양층과 물의 Pb, Cu, Zn 및 Fe 등의 함량을 조사하였고 그 주변에 자생하는 고마리, 마름 및 노랑어리연꽃의 중금속 농축량과 부위별 중금속 농축량을 조사하였다. 그리고 재료식물내의 중금속 농축량과 서식지 토양의 중금속 함량과의 관계를 밝히기 위해 재료식물내의 중금속 함유량과 토양의 중금속 함량간의 상관계수를 조사하였다. 실험실 조건하에서 재료식물의 중금속 흡수경향을 조사하기 위해 재료식물 중 고마리를 선정하여 Pb, Cu 및 Zn 등을 여러 농도로 처리한 용액에 고마리의 뿌리부분을 침수하여 재배한 후 그농축량을 측정하였고, 그 결과를 7개 채집지에서 자생한 고마리의 중금속 농축량의 측정치와 비교 분석하였다. 7개 채집지에서 자생한 고마리의 부위별 중금속 농축량은 Pb와 Zn의 경우 줄기<잎<뿌리의 순서로 증가하였고 Cu와 Fe는 잎<줄기<뿌리의 순서로 증가하였으며, 중금별 농축량은 Pb$\leq$Zn의 순서로 증가하였다. 고마리의 배양 실험 결과, 서식지에서 조사된 결과인 잎과 줄기에서 Pb

This study was to evaluate the efficiency of different solvent systems to extract active ingredients from different parts of medicinal plants used as oriental medicinal herb in the cosmetic industry. We tested efficacies related to the antioxidative effects and UV absorption of herbal extracts as complex of active ingredients, not each single ingredient. When extracting medicinal plant which is used effective medicine, we should consider the collecting conditions like collecting time, place, part and extracting conditions like solvent, temperature, time, and etc. Among them, extraction solvent and collecting part are very important factors for the efficacy. As increased interest in medicinal plants, more intensive studies on collecting conditions and extracting processes were needed for the developments in the herbal ingredient industry. We evaluated the efficiency of different solvent systems to extract active ingredients from different parts of plants (Terminalia chebula, Syzygium aromaticum, Paeonia lactiflora, Morus alba, Scutellaria baicalensis) widely used as medicine and food. As results, we found that proper condition can make better data and decrease the required quantity.

This study was conducted to investigate the association of race distribution of Pyricularia oryzae with rice cultivar and location. Races present in a given location were different in cultivars, and the races from a given cultivars were different by location. For precise study of race distribution, it needs to identify isolates by considering cultivation ratio and collection area. There are great differences between the resistant degree in the upland blast nursery and on the resistant degree of the leaf blast and panical blast in the paddy field. The number of virulent races in a rice cultivar was not related with the resistant degree in blast nursery or in paddy field.

This study was conducted to get basic information on the occurrence of plant-parasitic nematodes for the establishment of nematode management strategy in major potato production areas in Korea. Nationwide soil collection was done in 11 areas of Cheju, Yesan, Gimchun, Goryoung, Hong chun, Pyungchang, Gimjae, Milyang, Namwon, Gangnung, and Inje in 2004-2005. Root-hot nematode juveniles(J2) were detected in 30 samples among the 50 samples. The average density was 12-69 J2/100cc soil. Pratylenchus sp., Helicotylenchus sp., Ditylenchus sp., Tylenchus sp., and Tylenchorhynchus sp. were also detected in various locations, however, their densities were very low. Root-knot nematode females were collected from tomato roots inoculated with the potato field soils for PCR-RFLP identification. The females from Cheju, Milyang, and Goryung showed PCR products of 500 bp. And the Dra I restriction enzyme digestions showing 290 bp and 230 bp fragments confirmed their identity as Meloidogyne hapla.

본 연구는 우리나라 전역에 본포하는 범의귀과 수국속(Hydrangea L.) 식물인 산수국의 잎에서 열수추출하여 활성된 지표물질중 하나인 하이드란지놀(Hydrangenol)의 함량변화에 대해서 논하고자 한다. 산수국(H. serrata f. acuminata)잎을 추출한 결과 Hydrangenol, Diam-sep5-Rt8.2, Thunberginol compound, Hydrangenoside 등이 확인되었다. 특히, 최근 동물 임상 실험에서 항비만, 근개선 및 노화된 피부의 개선 등에 효과가 있다고 검증되었다. 2019년 수행된 추출실험 결과, 하이드란지놀은 산수국의 생육 조건에 따라 함량의 변화가 있는 것으로 나타났다. 2019년 5월 23일부터 6월 24일까지 소백산과 무등산 등 전국에 여러 생육지에서 채집한 산수국의 하이드란지놀의 함량은 0%로 파악되었으나, 그 이후 채집된 시료에서는 하이드란지놀의 함량이 일부 확인되었다. 산수국은 생육초반에는 하이드란지놀의 활성이 나타나지 않는 것을 확인 할 수 있었고, 개화시기 이후 잎의 생장이 어느 정도 진행된 상태에서 활성이 보이는 것을 확인해 볼 수 있었다. 하지만 온도 및 광량 등 생육조건에 따라서 하이드란제놀의 함량의 변화가 뚜렷하게 나타나 추가적인 재배 및 생리 실험 연구가 필요하다.

Phytophagous insects were surveyed from field populations of Compositae weeds in the order Campanulales. Forty five insect species including unidentified ones of 43 genera in 5 orders and 17 families were recorded from 16 species in 12 genera of Compositae weeds. The hemipterans and coleopterans were the most abundant insects representing 13 and 13 species, repectively. Aphids and leaf beetles were important phytophagous insects on Compositae weeds. The potential biological control insects were Uromelan gobonis and Aethes cnicana on Cirsium japonicum var. ussuriensis and Cryptosiphum artemisiae on Artemisia lavandulaefolia. The leaf beetles, Chrysolina aurichalcea, Longitarsus succineus, Basilepta fulvipes, and Hamushia konishii were often collected from A. lavandulaefolia. Aphids and leaf beetles showed host specificities. The roles of hemipterans collected from the flowers of A. lavandulaefolia and Erigeron canadensis were questionable.

Five coastal plant species, Artemisia fukudo, Aster sphathulifolius, Plantago camtschatica, Sedum oryzifolium, and Setaria viridis, were collected from the coastal region of Ulleung Island (Ulleung-Do, South Korea). Thirty-six endophytic fungi were isolated from the roots of these plants, and all were identified by using PCR with the following specifications: internal transcribed spacer 1 (ITS1), 5.8S rRNA, and ITS2 regions. Phylogenetic analysis indicated that all fungal strains belong to the phylum Ascomycota and comprise four orders (Capnodiales, Eurotiales, Hypocreales, and Pleosporales). Among all the identified species, the Eurotiales species were more abundant than species in the other orders. Nine different genera (Alternaria, Aspergillus, Cladosporium, Exserohilum, Fusarium, Neosartorya, Penicillium, Phoma, and Pyrenochaeta) in the four orders were confirmed. Penicillium and Aspergillus species were the most dominant species among the endophytic fungi isolated from the coastal plants. Shannon's diversity index (H') ranged from 0.684 to 1.609, and the endophytic fungi in S. oryzifolium was more diverse compared to the endophytic fungi in the other plants.

미국 J.C. Raulston 식물원에는 한국자생 조경수목 36과 110종 3품종이 재배되고 있다. 이중 때죽나무 'Emerald Pagoda' 신품종은 1985년 미국 국립식물원 식물탐사팀과 J.C Raulston이 소흑산도에서 꽃이 많고 잎이 크고 두꺼운 신품종으로 등록한 우리나라 자생종으로 미국내에서 감상가치가 매우 뛰어난 것으로 평가 받고 있다. J.C. Raulston은 이 때죽나무를 품종명 'Sohuksan'이라고 명명하였다가 'Emerald Pagoda'로 개칭하였다. Raulston은 소흑산 때죽나무를 수화물에 보관하여 미국에 도입했다. 도한 아왜나물를 진도에서 채집하였는데, 이것은 지금도 'Chindo'라는 품종으로 불이고 있으며 미구내 동남부 지바으이 조경에 적응성이 높고 감상가치가 높아 대량번식 및 보급 중에 있다.
