A new furofuran lignan, 4-hydroxykobusin (3), together with known lignans, kobusin (1), and 7,7'-dihydroxybursherenin (2), were isolated from the whole plant of Geranium thunbergii Sieb. et Zucc (Geraniaceae). The structures were determined based on the spectral data and a comparison with the published data. This is the first report of the presence of furofuran lignan in Geranium species.

Three flavonoids (1 - 3) and three phenolic compounds (4 - 6) were isolated from the whole plant of Geranium thunbergii Sieb. et Zucc (Geraniaceae). Their structures were determined by chemical and spectral analysis. These compounds were examined for the inhibitory activity of IL-6 production in $TNF-{\alpha}$ stimulated MG-63 cell. Among the isolated compounds, gallic acid (4) and gallic acid methyl ester (6) showed potent inhibitory activity.

미기록 외래식물인 세열미국쥐손이(쥐손이풀과)와 유럽패랭이(석죽과) 2종을 각각 제주도 서귀포시와 경남 합천에서 발견했다. 세열미국쥐손이는 열매에 선모가 있으며, 종자에 뚜렷한 망상무늬가 있는 특징으로 근연종들과 뚜렷하게 구분된다. 유럽패랭이는 꽃이 취산화서로 달리며, 꽃받침에 털이 있는 특징으로 근연종들과 구별된다. 이에 대한 기재, 도해, 사진 및 근연분류군과의 검색표를 제시한다.

현재 한국에서 시판되고 있는 화분식품 16종을 검사하여 본 바, 15 종에서 원형 그대로의 화분임을 확인하였다. 따라서 이들 화분의 기원식물을 감별하였는 바, 국화과, 백합과, 사초과, 층층나무과, 소나무과, 자작나무과, 쥐손이풀과, 콩과, 참나무과, 벼과의 식물 화분이었다. 이들 화분은 그 표피를 그대로 지니고 있으므로 식이성 allergen으로 작용할 우려가 있다. 16종의 화분식품중 한가지 만이 화분 표피를 함유하고 있지 않았다.

A new variety, Geranium koraiense var. hallasanense B.-J. Woo & S.-J. Park, is described here from Jeju Island, Korea. The new variety is distributed only in Jeju Island, and readily distinguished from the other varieties of G. koraiense by its shape of radical leaf division, rounded or undulate petal apex, glabrous petal veins, densely pubescent stems, and stylar portion pubescent with trichomes in basal 1/4 portion. A key to the varieties of G. koraiense is provided.

쥐손이풀속(Genus Geranium) 40분류군에 대하여 종자산포형태에 따른 생식형질을 조사하고, 이들의 분류체계 및 진화경향성을 논의하였다. 종자산포시 분과와 까락이 탄력적으로, 위로 감겨 올라가면서 종자가 산포되는 Geranium아속과 종자산포시 분과와 까락이 완전히 분리되어 종자가 산포되는 Robertium아속으로 구분된다. Geranium아속은 다시 종자를 일시적으로 유지해 주는 분과의 부속체기저부에 강모가 있는 Geranium절, 포크형태와 같은 갈고리 모양의 Dissect절. 강모나 갈고리형의 부속 체를 가지고 있지 않지만 분과가 비틀어지면서 종자를 유지해 주는 Tuberosa절로 분류되어진다. Robertium아속은 종자산포시 종자가 까락과 중심주로부터 모두 분리되면서 분과의 표벽이 심하게 주름이 지는 Ruberta절과 분과의 표벽에 주름이 없는 Batrachioides절과 Triloph절로 나어진다. 종자산포방식에 따르면 Geranium아속이 Robertium 아속보다 더 진화한 분류균으로 생각된다.

Phytochemical investigation of the MeOH extract of the aerial parts of Geranium eriostemon resulted in the isolation of one triterpene, three furofuran lignans, one syringic acid and four flavonoids. Their chemical structures were characterized by spectroscopic methods to be oleanolic acid (1), (-)-kobusin (2), (-)-eudesmin (3), (+)-magnolin (4), syringic acid (5), quercetin (6), juglanin (7), juglalin (8), and hyperin (9). All compounds (1 - 9) were isolated for the first time from this plant source and the compounds 2 - 4 were reported first from the genus Geranium. Compounds 4 - 6 exhibited moderate cytotoxicity against four human cancer cell lines in vitro using a SRB bioassay.

The localization of cellulase were investigated in the capitate glandular trichomes of Pelargonium ${\times}$ fragransby a transmission electron microscopy. The secretory cells of capitate trichomes involved in biosynthesis and its secretion. Secretory material is transported to the space between the plasma membrane and cell wall, and subsequently accumulated in the secretory cavity. The splitting of secretory cell wall during the formation of secretory cavity is suggested that wall-forming enzymes, such as cellulase, may contribute to the wall separation process. Cellulase reaction product was localized in the secretory cell, the secretory cavity and in the subcuticular wall of glandular trichomes. Reaction products were present over fibrillar matrix in the secretory cavity associated with both the inner wall and the subcuticular wall.

Naturalization centers are hotspots where accidently introduced seeds first germinate and grow. Railways play important roles as corridors for movement, having positive effects on species dispersal and persistence, though they can also be invasion routes for undesirable plants. Geranium purpureum Vill., a new alien species in Korea, was found at the Bumil Railway Station, Busan, Gyeongsangnam-do, Korea. Most native Geranium species in Korea belong to the subgenus Geranium and section Geranium, but G. purpureum belongs to the subgenus Robertium and section Ruberta, with the "carpel-projection" method of seed dispersal. In other countries, G. purpureum is often compared with G. robertianum L., which is an ornamental plant in Korea. We assume that G. purpureum is a casual alien plant and that it is not likely to spread to other provinces, as it scarcely survives when the mean temperature in January is below $4^{\circ}C$. Moreover, it has not been found further north than Busan. We provide a key of allied taxa, information about the habitat, a description of the morphological characters, illustrations, and photographs.

Compare to investigate the taxonomic utility of infragenera system and interspecific of Asian Geranium, we examined the fruit and seed morphology from 35 taxa. The fruit shape and seed's dispersal way did so that may divide subgenus or some part section to do could reason evolutionary trends. That is, at seed dispersal, the awns of section Geranium of subgenus Geranium, ramains attached at the top of rostrum, though fairy easily broken off, because seed increases awn's elasticity by diffusive way, it is long characteristic seed\`s dispersal distance, and subgenus Robertium observed that seed dispersal distance is short because it is no awn's elasticity by way that seed dispersal is gone as awn drops with rostrum. Also, section Geranium of subgenus Geranium and subgenus Robertium act role that awn keeps temporarily breed swerving with mericarp instead of bristle because section Tuberosa of subgenus Geranium is not bristled function that keep temporarily breed because mericarp bristled on base at seed dispersal do while. Therefore, is thought that is talon that when consider formation's development and function regarding this seed dispersal function, subgenus Geraniuum evolves more than subgenus Robertium. Seed morphology can divide by 2 subgenera(Geranium, Robertium) according to pattern of seed coat. and Seed's morphology characteristic(whole shape, color, form of seed apical and base, micropyle area, hilum area, chalaza, and position of seed hilum area), can distinguish some species, but is thought that is not reasonable as for discernment characteristic form and nature by repetition of characteristic form and nature. Especially, infrasection do in fruit and seed's morphology that is handling in this research that know to argue classification system and relationship by repetition of characteristic form and nature difficult. To all reliable truth, cytological, ecological, embryology, and molecular genetics research about talon is considered that should be achieved section Geranium that do not handle yet.
