  • Natural resource plants have been useful and helpful materials for human to against diseases and Prevention since ancient Egyptian and Roman times. However, according to recent survey, its habitat and indigenous are continuously decreased and almost extinct some valuable species, as Adonis vernalis, Digitalis lanata etc., especially in Eastern Europe and east Asian countries due to radical political and social reforms. ESCOP and FAO have already initiated to protect the endangered species for conservation, protection and propagation technology but it is not easy tasks without global concerning. Most natural resource plants have volatile components in essential oils and its consumption and demanding is increased every year, which contained certain compounds have no side effects and good properties for biological activities. Essential oils of natural resource plants are also well known for medical purposes, such as Central Nervous System (CNS, linalool), anticancer (d-limonene, perillyl alcohol, etc.), microbial and fungicidal activities (menthol, borneol, etc). Essential oil also used for natural therapy to prevent and increase immune systems instead of chemical synthesis drugs. With this, researchers of natural resource plants are ultimately faced to develop and optimal technology for increasing the Korean farmer's income by high added-value herbal products in present and future.

  • The inhibition of rat lens aldose reductase (AR) in vitro using methanol extracts from Korean folk plants was investigated. Among them, the extracts of Saussurea grandifolia and Rumex crispus showed highest inhibition of AR. $IC_{50}$ values of the extracts from S. grandifolia and R. crispus were demonstrated 0.07 and 0.05 mg/ml, respectively. Korean folk plants such as S. grandifolia and R. crispus has a possibility of new natural resources for the inhibition of AR.

  • Distribution of vascular plants in Yangyang-gun were investigated 12 times from Apr. to Sept., 2008. In the result of survey, the flora of this area consist of 412 taxa totally; 89 families, 259 genera, 366 species, 5 subspecies, 37 varieties and 4 forms. There were remarkable plants such as 11 taxa of Korean endemic plants, 58 taxa of specific plants which were designated by the Ministry of Environment, 2 taxa of endangered plants of Ministry of Environment, 7 taxa of rare, endangered plants of Korea Forest Service and 28 taxa of afforestation plants and 296 taxa of useful plants. Furthermore, 36 taxa of naturalized plants (8.74%) were also observed in this area. Vegetation of investigated area was conserved well. However, vegetation has been destroyed rapidly due to construction of commercial complex for human recreation such as condominiums and stores. Therefore, it is need to efficient management of the water quality and vegetation by conservation strategies from huge visitors.

  • 2009년 3월부터 2009년 9월까지 경상남도 양산시 일대의 관속식물 및 자원식물분포조사를 수행하였다. 본 조사를 통해 확인된 조사지역 내의 소산 관속식물은 90과 256속 376종 4아종 41변종 6품종으로 총 427분류군으로 확인되었다. 조사 지역에서 분포하고 있는 427분류군의 식물자원 유용도를 분석한 결과 식용자원식물이 167종류, 섬유용 자원식물이 6종류, 약용자원식물이 118종류, 관상용 자원식물이 52종류, 초지 자원식물이 132종류, 공업원료자원이 2종류, 염료용 자원식물이 98종류, 목재용 자원식물이 15종류, 용도가 밝혀지지 않은 식물이 101종류로 구분되었다. 이 중 식용자원, 약용자원, 초지자원, 염료용자원이 비교적 많이 분포하는 것으로 나타났다. 특기할만한 식물로는 한국 특산 관속식물이 총 16분류군, 환경부지정 특정식물종이 36분류군으로 각각 조사되었고, 귀화식물은 38분류군으로서 약 8.9%를 차지하였다. 조사지역의 식생은 비교적 양호한 편이었으나, 저지대 대부분이 농경지로 활용되며, 사찰과 많은 여가시설, 탐방객 등으로 인해 귀화식물의 분포가 빠르게 확산되고 있어 생태계의 교란이 우려되는 상황이다.

  • 선행연구를 통해 18종의 호박 품종에 대한 엽위별 paraquat에 대한 내성 반응을 조사한 결과, 1엽<2엽<3엽<4엽 순이었다. 이들 품종 중에서 엽령간 뚜렷한 내성차이가 있는 중앙애호박의 경우 4엽은 1엽에 비해 paraquat에 대해 3배 이상의 높은 내성을 보였다. 또한 이들 4엽의 물 추출물과 paraquat를 혼용하여 옥수수 경엽에 처리시 paraquat 약해를 경감시켰다. 따라서 본 연구는 paraquat 약해를 경감시키는 물질이 어린 호박잎에 존재하는지를 알아보기 위하여 수행하였다. MeOH 추출물보다 물 추출물에서 paraquat 활성경감이 더 높아서 물 추출물을 실리카겔과 Sephadex LH-20 칼럼크로마토그래피와 TLC, HPLC를 이용하여 paraquat 활성 경감 효과를 보이는 순수물질을 얻어 NMR을 통해 분석한 결과 malic acid로 추정되었다. 따라서 malic acid가 paraquat 활성경감 물질여부를 확인하기 위하여 malic acid와 paraquat를 옥수수에 동시 처리하였다. 처리 후 1일째 $100{\mu}M$ paraquat를 단독으로 처리한 경우 옥수수 잎 피해가 62% 발생하였으나 $100{\mu}M$ paraquat에 malic acid를 각각 0.1, 0.3, 0.5 및 1% 혼용처리한 경우 잎 피해가 전혀 발생하지 않았다.

  • To search for the aldose reductase (AR) inhibitors from Korean folk plants, the inhibition of rat lens AR in vitro using the methanol (MeOH) extracts from Korean folk plants in Chungcheong Province was investigated. Among Korean folk plants tested, the MeOH extract of Persicaria longiseta showed highest inhibition of AR ($IC_{50}$ value, $5.14{\mu}g/ml$). Consequently, P. longiseta has a possibility of new natural resources for the development of AR inhibitor for the prevention of diabetic complications.

  • This study was performed to investigate the flora and plant resources of Mt. Gamak (537.8 m) from April to October 2007. The collected vascular plants were composed of all 478 taxa including cultivated species, and classified into 410 species, 3 subspecies, 61 varieties, and 4 forms of 284 genera under 94 families. Six taxa of the Korean endemic plants and 4 taxa of the rare and endangered plants were also distributed in this mount. Resource plants were categorized into edible 222, pasturing 208, medicinal 183, stainable 134, ornamental 96, timber 20, fiber 6 and industrial 4 taxa, respectively. Floristic geography of the investigated area was regarded as the boundary between middle parts in floristic pattern of the Korean Peninsula.

  • The natural habitats and distribution of five rare plants were recently discovered in Korea. Salomonia oblongifolia DC., which grows in mountain wetlands, was found in Gijang-gun, Busan, Gokseong-gun, Jeollanam-do, and Shinan-gun, Jeollanam-do. Glaux maritima var. obtusifolia Fernald, which grows along the coast, was found in Yangyang-gun, Gangwon-do, Pohang-si, Gyeongsangbuk-do and Buk-gu, Ulsan. Tillaea aquatica L. and Limosella aquatica L., which was previously not known to be present in Korea, were discovered in Gijang-gun, Busan for the first time. Apocynum lancifolium Russanov, which has a narrow distribution range in Korea, was also found in Samcheok-si, Gangwon-do, Ansan-si, Gyeonggi-do, Siheung-si, Gyeonggi-do, Jung-gu, Incheon, Yeongdeok-gun, Gyeongsangbuk-do and Shinan-gun, Jeollanam-do.
