This study was conducted to clarify the taxonomic implications of F. chiisanensis Nakai based on morphology and flavonoids of four taxa of Fraxinus [F. chiisanensis Nakai, F. mandshurica Rupr., F. chinensis Roxb. var. rhynchophylla (Hance) Hemsl. and F. sieboldiana Blume] in Korea with one species of China and Japan (F. platypoda Oliv.). Morphologically F. chiisanensis was clearly distinguished from other taxa due to the presence of panicle from leafless lateral bud of previous year, apetalous flower, persistent calyx, and brownish naked bud. A survey of the foliar flavonoids of five species showed two distinctive chemical types. Unique flavones with flavonols, C-glycosylflavone and flavanone were detected in F. chiisanensis (chiisanensis type), while only flavonols, C-glycosylflavone, and flavanone were present in other four taxa (chinensis type). This study showed that F. chiisanensis was not a hybrid between F. mandshurica and F. chinensis var. rhynchophylla, but an endemic taxon distributed in southwestern Korea. Morphologically F. chiisanensis should be included into subgen. Fraxinus, sect. Melioides according to Chang and Qiu's classification. F. platypoda, a taxon of sect. Meliodies in China and Japan, was different from F. chiisanensis with respect of scaled bud, decurrent wing of samara and the lack of flavones (chinensis type). Since four American taxa of sect. Melioides contained flavones (chiisanensis type), they are more closely related with F. chiisanensis chemically.

Basophils and mast cells play an important role in $Fc{\varepsilon}RI-mediated$ allergic reaction as effector cells. We studied the effects of Acanthopanax chiisanensis on $Fc{\varepsilon}RI\;{\alpha}$ chain expression in human basophilic KU812F cells. Ethanol extracts from root and stem of A. chiisanensis were tested for inhibitory effects of $Fc{\varepsilon}RI\;{\alpha}$ chain expression. The cell surface $Fc{\varepsilon}RI\;{\alpha}$ chain expression was examined by flow cytometric analysis. All of the extracts of A. chiisanensis reduced the cell surface $Fc{\varepsilon}RI\;{\alpha}$ chain expression. Furthermore, A. chiisanensis extracts caused a decrease in the level of $Fc{\varepsilon}RI\;{\alpha}$ chain mRNA level and $Fc{\varepsilon}RI-mediated$ histamine release. These results suggest that root and stem extracts of A. chiisanensis play an important role in anti-allergic activity via down-regulation of $Fc{\varepsilon}RI\;{\alpha}$ chain expression and decrease in release of inflammatory mediator such as histamine.

The chloroform and the ethyl acetate fractions from the roots of Acanthopanax chiisanensis exhibited a significant inhibition of prostaglandin E$_2$ (PGE$_2$）production in rat peritoneal macrophages stimulated by the protein kinase C activator, 12-O-tetradecanoylphorbol 13-acetate （TPA）. Hyperin was isolated as an active principle from the ethyl acetate fraction. It sup-pressed not only $PGE_2$ production but also nitric oxide （NO） production in vitro in a concentration dependent manner. their $IC_{50}$, being 24.3 and $32.9{\;}{\mu}M$, respectively. Hyperin also caused a significant inhibition of increase in acetic acid-induced vascular permeability in mice in vivo.

Many infraspecific taxa within Lespedeza maximowiczii and hybrids with related species have been described, but taxonomic verification remains controversial. We examined the morphological traits of hybrids (L. chiisanensis and L. patentibicolor) and infraspecific taxa (var. tomentella, elongata, and tricolor) and analyzed their genetic structures using microsatellite loci. Flower and leaflet shapes in var. tomentella and elongata were within the range of variation of those in var. maximowiczii, and individuals in the two former varieties were grouped into var. maximowiczii. Lespedeza maximowiczii var. tricolor was similar to L. buergeri in terms of the structure and flower color, whereas the leaflet and bracteole shapes of var. tricolor were similar to those of var. maximowiczii. Based on the genetic structure (K = 3), var. tricolor had a mixed lineage with L. maximowiczii and L. buergeri. In addition, these formed a distinct lineage at K = 5. For two hybrids, the flower and leaflet structure in L. chiisanensis did not differ from those in L. maximowiczii, whereas the flowers of L. patentibicolor were within the range of variation of L. bicolor. In addition, L. chiisanensis and L. patentibicolor were assigned to L. maximowiczii and L. bicolor, respectively, based on the genetic structure. We treated var. tomentella and elongata as a forma, f. friebeana, because L. friebeana preceded var. tomentella, whereas var. tricolor was treated as a distinct species, L. tricolor. Lespedeza chiisanensis was recognized as a synonym of L. maximowiczii. Lespedeza patentibicolor was considered to be L. bicolor.

We used enzyme electrophoresis to evaluate genetic diversity in five populations of endemic ash, Fraxinus chiisanensis in Korea. Of 15 putative allozyme loci examined 26.7% were polymorphic and expected heterozygosity for the species was low (0.082). Within the range, population were highly differentiated ($F_{ST}$=0.356) and little genetic variation was explained by geography. The pattern of distribution of variation showed low genetic variation within populations and pronounced divergence among populations, which was consistent with the prediction for the effects of limited gene flow and local genetic erosion. Although the frequencies of male plants were dominant ranging from 79.3% to 89.4%, most mating events seems to be inevitable mating between relatives in small populations based on heterozygote deficiency of this species. Small effective population size and the limited dispersal contributed to the low rates of gene flow within as well as between populations.

'O Ga Pi Ip' has been used in Korea to cure rheumatism, neuralgia, edema, dematopathy, and impotence. The botanical origin of the crude drug has not been confirmed pharmacognostically. To clarify the botanical origin of 'O Ga Pi Ip', the morphological and anatomical characteristics of the leaves of Acanthopanax species growing in Korea and Japan, A. chi-isanensis Nakai, A. Koreanum Nakai, A. rufinerve Nakai, A. senticosus (Rupr.et Maxim). Harms, A senticosus (Rupr.et Maxim.) for inermis Harms, A. seoulense Nakai, A sessiliflorus (Rupr. et Maxim.) Seem, A. divaricatus Seem, A. sieboldianum Makino were compared. As a result, it was determined that 'O Ga Pi Ip' was the leaf of A. sessiliflorus (Rupr. et Maxim.) Seem, A chiisanensis Nakai, and A. koreanum $Nakai_I$.
