물봉선속(봉선화과)의 1신종인 꼬마물봉선이 한국의 경상북도 영천시 보현산에서 발견되어 기재되었다. 신종은 근연종인 물봉선(I. textorii)에 비해 1/2 크기의 꽃, 급격히 좁아지는 하악편, 1/2 회에서 1 회 감기는 거, 타원형인 측화판의 선단부 열편을 가짐으로써 뚜렷하게 구별되었다. 본 연구에서 이들 두 종의 검색표를 제시하였다.

Over the past 15 years, downy mildew became the most destructive foliar disease in cultivated Impatiens species (Balsaminaceae) worldwide. A previous study had revealed that the causal agent was not Plasmopara obducens (Oomycota, Peronosporales) but Plasmopara destructor on Impatiens walleriana, and Plasmopara velutina on Impatiens balsamina. This hints to a relatively high degree of specialization of Plasmopara on Balsaminaceae. Therefore, it was the aim of the present study to perform multigene phylogenetic analysis and detailed morphological investigation for several Korean downy mildew samples parasitic to cultivated I. walleriana, and I. balsamina, but also to a northeast Asian wild plant, Impatiens textori. It was revealed that I. textori harbors a new species, which is introduced and described here as Plasmopara elegantissima.

Impatiens textori Miquel (Balsaminaceae) is an annual plant growing in most parts of Korea. The herb of this plant has been used for the external application of snake poison and the bruise. Previous investigations conducted with the herbs have demonstrated it to contain three flavones and three flavone glycosides. Continuing to previous reports, quercetin, kaempferol and acacetin $7-O-{\beta}-D-glucoside$ were isolated from the herbs of this plant.

Four flavonoids were isolated from the ether and ethylacetate extracts of Impatiens textori Miquel(Balsaminaceae). The structures were elucidated as luteolin(I), apigenin(II), chrysoeriol(III), and chrysoeriol 7-glucoside(IV) by physico-chemical and spectroscopic methods. These compounds were isolated from this plant for the first time.

Impatiens balsamina Linne(Balsaminaceae) known as 'BONG SUN HWA' in Korea and has been used for the treatment of scrofulosis, carbunculus and dysenteria etc. Bioassay-guided fractionation of MeOH extract from the whole plants of Impatiens balsamina has afforded a simple naphthoquinone derivative, 2-methoxy-1,4-naphthoquinone. The structure of this compound was established by spectroscopic methods. This compound possessed strong antifungal activity against Candida albicans, AspergiIlus niger, Crytococcus neoformans and Epidermophyton floccusum. The activity of 2-methoxy-1,4-naphthoquinone on E. floccusum $(MIC{\;}:{\;}5.0{\;}{\mu}g/ml)$ was the same potency as that of nystatin. It showed also strong antibacterial activity against gram-positive bacteria Bacillus subtilis as well as gram-negative bacteria Salmonella typhimurium. Although the activity of this compound on gram-negative bacteria was lower than that of gram-positive bacteria.

Impatiens cardamomensis S. H. Cho, C. K. Lim & H. Won, a new species of the family Balsaminaceae from the Cardamom Mountain Range in southwestern Cambodia, is described and illustrated. The species is similar to I. noei from Thailand in that it possesses solitary flowers, fusiform capsules, and compressed seeds, but is readily distinguished by its ovate to widely ovate leaves, shorter petioles, widely elliptic dorsal petals and smaller seeds.

In this study we examined the concerned literature for clinical use of Balsaminaceae plants focusing on the latest literature "zhong hua ben cao"(chinese materia medica, 1998). The findings were summarized as follows: 1. As an original plant, 27 species have been reviewed. 2. As a result of investigating oriental drug names by medicinal using part, a survey reported that the total of 22 species of oriental drug names, including 14 species of herba, 3 species of flos, 4 species of radix and rhizoma, and 1 species of semen, are being used for clinical use. 3. When we examined oriental drugs with five flavors by calculating and arranging their nature, effect, toxicity with points for conveniences sake, pungent and bitte showed 13 points, respectively, as main flavors. In drug nature, warm property of drug indicated 10 points and cold property of drug obtained 6 points. But as for other oriental drug, it is thought that we can recognize their significance. 4. With respect to efficacy, activating blood drug reached 10 kinds and wind- damp-dispelling 7 kinds, according to the examination. 5. In the examination on components and medicinal action, we examined that components are recorded in only impatiens balsamina's whole grass, flowers, root, root stems, and seeds, and Impatiens noli-tangere's whole grass. In medical action, we found out that the components are recorded in impatiens balsamina' flowers and seeds; impatiens noli-tangere's whole grass and flowers; and Impatiens textori' whole grass. 6. As a result of examining clinical prescription, the total of 84 kinds of clinical prescriptions by disease nature were examined, of which the prescription of Impatiens balsamina showed 19 cases in total, which was remarkable.

원기재문과 기준표본을 근거로 Impatiens furcillata의 분류학적 실체와 형태적 특성을 재검토하였다. 그 결과, I. furcillata는 줄기 및 화경에 털이 없고, 화경은 아래로 처지며, 꽃은 홍백색인 특징을 가져 다른 한국산 물봉선속의 분류군들과 명확히 구분되었다. 특히, 이와 동일한 형태적 특성을 가지는 I. hypophylla var. koreana (처진물봉선)와 I. kojeensis (거제물봉선)는 I. furcillata의 이명으로 처리하였다. 또한 I. furcillata의 국명은 '산물봉선' 대신 '처진물봉선'으로 변경하였다.

From the herbs of this plant, six compounds were isolated and their structures were characterized as dieicosyl ether (1), scopoletin (2), ${\alpha}-spinasterol-3-O-{\beta}-D-glucopyranoside$ (3), kaempferol (4), quercetin (5), and quercetin 7, 3', 4'-trimethylether-3-O-rutinoside (6) by chemical and spectroscopic evidences. These compounds were isolated for the first time from this plant and compound 6 was first isolated from nature.

Impatiens textori Miquel (Balsaminaceae) is an annual plant growing in most parts of Korea. The herb of this plant has been used as a medicine for external application for the snake poison and the bruise. From the herbs of this plant, two flavone glycosides were isolated and the structures were elucidated by chemical and spectroscopic methods. The compounds were identified as apigenin 7-O-glucoside (cosmosiin) (I) and luteolin 7-O-glucoside (II). These compounds were isolated from this plant for the first time.
