Cupressaceae plants are used in traditional folk medicine. whose extracts have been found to possess some bioactivities. (－)-Yatein is a lignan of the dibenzyl-butyrolactone type. that has been isolated from some Cupressaceae plants. It was reported that (－)-yatein. isolated from plants. showed different activities from the synthetic yatein ［3］. Hence. the enantiosetective determination of yatein from synthetic materials and natural products would be necessary. (omitted)

Pseudomonas aeruginosa에 대한 항균물질을 찾기 위하여 한의학에서 전통적으로 사용되어 오던 34종류 약용식물로부터 에탄올 추출물들을 분리하여 항균활성을 조사하였다. Gardenia jasminoides, Arctium lappa, Citrus unshiu 및 Phellodendron amurense 등의 에탄올 추출물들이 P. aeruginosa ATCC 27853에 대해서 항균활성을 나타냈다. 이들 중 Gardenia jasminoides의 에탄올 추출물은 P. aeruginosa에 대해 강한 항균활성을 나타냈다. 앞으로 이들 약용식물들의 추출물들이 P. aeruginosa에 대한 천연항균물질로서 사용될 수 있을 것으로 기대된다.

꽃매미의 식물에 대한 선호도을 조사한 결과, 가죽나무와 포도나무를 가장 선호하였으며, 사과나무, 배나무, 무궁화나무, 소나무와 복숭아 나무는 선호하지 않는 것으로 나타났다. 7종 식물에 대하여 꽃매미 약충과 성충은 가죽나무와 포도나무에서 가장 오래 생존하였고, 다른 식물에서는 생존기간이 짧았다. 과수열매에서는 거의 생존하지 못하였다. 꽃매미의 섭식행동 분석결과, 약충과 성충 모두 가죽나무와 포도나무에서 섭식하지 않는 시간(non-probing time)은 가장 짧았고, 체관부 섭식시간(phloem-feeding time)은 가장 길었다. 이를 제외한 나머지 식물과 열매에서는 체관부 섭식시간이 0분으로 섭식을 하지 못하였다. 5종 식물을 당 분석한 결과, 가죽나무는 sucrose 함량이 가장 높았고 fructose > glucose순으로, 포도나무에는 glucose > fructose > maltose > sucrose > rhamnose순이고, 사과나무는 glucose > fructose, 배나무는 glucose > unknown > fructose, 무궁화나무는 sucrose > glucose 순으로 당 성분이 존재하였다. Parafilm membrane 검정법으로 생존기간을 조사한 결과, 약충과 성충 모두 sucrose 5%용액에서 가장 생존기간이 길었으며, fructose 5%용액이 그 다음이었다. 이를 제외한 나머지 성분에서는 짧은 수명을 나타내었다. 분석된 당 성분의 조합에 의한 검정에서도 약충과 성충 모두 가죽나무와 포도나무의 당 성분조합에서 다른 당 성분조합과 비교하여 긴 수명을 보였다. 당 성분이 꽃매미가 기주를 선택하고 섭식하는데 영향을 미치는 것으로 생각된다.

Background : Plants belonging to 5 species of the genus Eleutherococcus are currently distributed in the Korean peninsula. The traditional medicine 'Ogapi', derived from Eleutherococcus sessiliflorus and other related species, and 'Gasiogapi', derived from Eleutherococcus senticosus, are frequently mixed up and marketed. Therefore, accurated identification of their origins in urgently required. Methods and Results : Candidate genes from nuclear ribosomal DNA (nrDNA) and chloroplast DNA (cpDNA) of Eleutherococcus plants were analyzed. Whereas the nrDNA-internal transcribed spacer (ITS) regions were useful in elucidating the phylogenetic relationships among the plants, the cpDNA regions were not as effective. Therefore, a combined analysis with nrDNA-ITS was performed. Various combinations of nrDNA and matK were effective for discriminating among the plants. However, the matK and rpoC1 combination was ineffective for discriminating among some species. Based on these results, it was found that OG1, OG4, OG5, OG7, GS1, GS2, and GS3 were derived from E. sessiliflorus. In particular, it was confirmed that GS1, GS2, and GS3 were not derived from E. senticosus. However, more samples need to be analyzed because identification of the origins of OG2, OG3, OG6 and GS4 was not possible. Conclusion : The ITS2, ITS5a, and matK combination was the most effective in identifying the phylogenetic relationship among Eleutherococcus plants and traditional medicines based on Eleutherococcus.

In the view of authenticity of Radix Scrophulariae, there were 2 genuine species, 1 species for substitution, and study of 6 species later on. 3. In the view of authenticity of Radix Rehmanniae Recens, there were 2 genuine species, 1 species for substitution, and study of 1 species later on. 4. In the view of authenticity of Rhizoma Picrorrhizae, all the original species was genuine species. 5. The each efficacy of origin-plants were reported in the main subject. Conclusions : The 15 original plants were present among the 3 medicinal herbs in the common family scrophul ariaceae. There were 2 genuine species in Radix Scrophulariae and Rhizoma Picrorrhizae.

Strawberry bacterial angular leaf spot (ALS) disease, caused by Xanthomonas fragariae has become increasingly problematic in the strawberry agro-industry. ALS causes small angular water-soaked lesions to develop on the abaxial leaf surface. Studies reported optimum temperature conditions for X. fragariae are $20^{\circ}C$ and the pathogen suffers mortality above $32^{\circ}C$. However, at the nursery stage, disease symptoms have been observed under high temperature conditions. In the present study, results showed X. fragariae transmission was via infected maternal plants, precipitation, and sprinkler irrigation systems. Systemic infections were detected using X. fragariae specific primers 245A/B and 295A/B, where 300-bp and 615-bp were respectively amplified. During the nursery stage (from May to August), the pathogen was PCR detected only in maternal plants, but not in soil or irrigation water through the nursery stage. During the cultivation period, from September to March, the pathogen was detected in maternal plants, progeny, and soil, but not in water. Additionally, un-infected plants, when planted with infected plants were positive for X. fragariae via PCR at the late cultivation stage. Chemical control for X. fragariae with oxolinic acid showed 87% control effects against the disease during the nursery period, in contrast to validamycin-A, which exhibited increased efficacy against the disease during the cultivation stage (control effect 95%). To our knowledge, this is the first epidemiological study of X. fragariae in Korean strawberry fields.

Objectives : This study is to propose the identification keys based on stereoscopic examination of 8 seed herbs in 2 categories (Phyllolobobii Semen (PS) with 4 Astragali Semen (AS), and 2 Lepidii seu Descurainiae Semen (LDS) with 1 Drabae Semen (DS)) which have difficulties in discrimination with visual observation. Methods : We reviewed the description of original plants and their medicinal parts from the literature. The original plants were collected, identified, confirmed as specimens, and compared to the samples distributed in the market. The first identification was made by visual observation, and insufficient points were supplemented by stereoscopic observation. Identification criteria were set by considering morphological characteristics of authentic herbs, percentage of adulterants, and distinction between authentic herbs and adulterants. Results : The original plants of PS and AS could be distinguished by upright or lying form of stem, color of flowers, number of leaflets, and presence of hair of fruits. LDS and DS could be distinguished by leaf arrangement on stem: radical or cauline, whole plants size, leaf division, color of flowers, and shape of fruits. The herbal medicines of PS and AS could be distinguished by seed surface pattern, size, and hardness. LDS and DS could be distinguished by size, shape, viscosity when chewed, and degree of mucous layer formation when soaked in water. Conclusions : This study suggests the identification keys of original plants and herbal medicines. Especially, since fine seed herbs are difficult to distinguish by visual observation, the stereoscope should be applied to the discrimination.
