Objective : For the purpose of developing Korean herbalogy of the plants to Iridaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article. Methods : The examined herbalogical books and research paper which published at home and abroad. Results : A list was made about Iridacease plant which are cultivated or grew naturally in Korea, after investigate the data on domestic and foreign Iridaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Iridacease's properties flavor, channels they use and effects were also noted, not to mention their toxicity. Iridacease (grew in Korea) was divided into 6 classes with 32 species. Out of those, 5 classes with 11 species were found serviceable which indicates 34% of all. Out of all 32 specified Iridacease plants, Iris plants were found 27 species, which were shown the most. And 7 classes of Iris plants were also selected the most in serviceable Iridacease. Out of all serviceable parts in Iridaceae, root parts took first place as 6 species. Conclusion ; There were totaled to 6 genera and 32 species in Iridaceae in Korea and among them medicinal plants are 5 genera, 11 species, some 34% in total.

A new method for separation and quantitative determination of isoflavone glucosides in rhizomes of Belamcanda chinensis (Iridaceae) by high performance liquid chromatography was elaborated. A reverse-phase system with a Spheri-5 RP-18 column using MeOH:HOAc:$H_2O$(24 : 5 : 71) as a mobile phase was developed. The isoflavonoids were detected at 268 nm and the analysis was successfully carried out within 15 min.

Six components were isolated from the $CH_2Cl_2$ fraction of Belamcanda chinensis rhizome by open column chromatography. Their structures were elucidated as ${\beta}-sitosterol$ (1), apocynin (2), decursin (3), iristectorigenin A (4), irigenin (5) and tectorigenin (6) by spectral analysis. Among these compounds, decursin (3) was isolated for the first time from a plant of the family Iridaceae.

Four compounds were isolated from the rhizome of Belamcanda chinensis (Iridaceae) by repeated column chromatography and were elucidated as iristectorigenin A, irigenin, tectorigenin and tectoridin by spectral analysis. The estrogenic activity of these isoflavones was tested using Ishikawa cells. Irigenin, tectorigenin and tectoridin were highly estrogenic ($EC_{50}\;=\;0.75$, 0.42 and $0.81\;{\mu}g/ml$, respectively), while iristectorigenin A exhibited weak estrogenic activity ($EC_{50}{\geq}4\;{\mu}g/ml$).

The aim of this study was to provide basic guidelines for conservation and management of endangered plants in the national parks of Korea. Iris dichotoma Pall. (Iridaceae), which is a popular garden plant, is considered a second-class endangered species by Korean government and it is listed as a EN (Endangered) species in Red Data Book of Korea. We analyzed ecological conditions of I. dichotoma habitats based on vegetation properties and soil characteristics. This species which is known to inhabit in grassland adjacent to the ocean of lowlands slope and its population was located at an elevation of 8 m to 11 m. In the study sites, the mean of soil organic matter, total nitrogen and soil pH were 6.16%, 0.234% and 5.39 respectively. Additionally, the genetic variation and structure of three populations were assessed using ISSR (Inter Simple Sequence Repeat) markers. The genetic diversity of I. dichotoma (P = 59.46%, H = 0.206, S = 0.310) at the species level was relatively high. Analysis of molecular variance (AMOVA) showed 82.1% of the total genetic diversity was occurred in within populations and 17.9% variation among populations. Lastly, we developed predicted distribution model based on climate and topographic factors by applying SDMs (Species Distribution Models). Consequently, current status of I. dichotoma habitats is limited with natural factors such as the increase of the coverage rate of the herbs due to ecological succession. Therefore, it is essential to establish in situ and ex situ conservation strategies for protecting natural habitats and to require exploring potential and alternative habitats for reintroduction.

Iris L. is a perennial genus comprising approximately 300 species worldwide, with the greatest number of endemic species occurring in Asia. Iris is one of the largest genera in the family Iridaceae and includes ca. 15 species native to Korea. Although chromosome number change, karyotype restructuring, and genome size variation play an important role in plant genome diversification, understanding the karyotype variation in Korean Iris species has been hampered by the wide range of base chromosome number (x = 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22) reported to date. This study documents the chromosome numbers, karyotype structure and genome size variation in Iris ruthenica K. Gawl., an endangered species in Korea obtained using classic Feulgen staining and flow cytometry. The chromosome number of all investigated plants from the nine populations was 2n = 42. All individuals studied possessed metacentric and submetacentric chromosomes. The genome size of the I. ruthenica in eight wild populations ranged from 2.39 pg/1C to 2.45 pg/1C ($2.42{\pm}0.02pg/1C$: $mean{\pm}SD$). This study provides the first report of genome size variation in Iris ruthenica in Korea. This study lays foundation for cytogenetic further analyses employing by fluorescence in situ hybridization (FISH) to better understand the chromosomal evolution in this species and in the whole genus.

Methods : The examined herbological books and research paper which published at home and abroad. Results : A list was made about Eriaceae plant which are cultivated or grew naturally in Korea, after investigate the data on domestic and foreign Eriaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Eriaceae's properties flavor, channels they use, effects, and toxicity were also noted. Eriaceae (grew in Korea) was divided into 9 classes with 48 species. Out of those, 3 classes with 14 species were found serviceable which indicates 29% of all. Out of all 48 specified Eriaceae plants, Rhododendron plants were found 26 species, which were shown the most. And 7 classes of Rhododendron plants were also selected the most in serviceable Eriaceae. Out of all serviceable parts in Eriaceae, leaf parts took first place as 12 species. Conclusion : There were totaled to 9 genera and 48 species in Iridaceae in Korea and among them medicinal plants are 3 genera, 14 species, some 29% in total.
