Sisyrinchium micranthum Cav., a newly naturalized species, was found in Seogwipo, Jeju-do. This species is native to Central and South America and is reported as a widely invasive species around the world. Sisyrinchium micranthum is a sister species of S. rosulatum E. P. Bicknell (Deung-Sim-But-Kkot in Korean), reported as an invasive species earlier in Korea, and both species are members of the subgenus Echthronema. Sisyrinchium micranthum is distinguished from S. rosulatum by the urceolate shape of its flowers and by the large size of its fruits and seeds. Its local name is "Yeon-Deung-Sim-But-Kkot" based on the light blue corolla. We also found that Sisyrinchium angustifolium Mill., previously used for Deung-Sim-But-Kkot, was misapplied. It belongs to the subgenus Sisyrinchium and is morphologically very different from S. rosulatum. We corrected the scientific name of Deung-Sim-But-Kkot by changing it from S. angustifolium to S. rosulatum based on the type specimens, original descriptions, and recent studies.

Topical natural antioxidants are a useful strategy for the prevention of oxidative stress mediated cardiovascular disease including atherosclerosis. From the viewpoint of this underlying principle, the screening of natural plant extracts with scavenging activity for pro-oxidant reactive species is a primary requirement for the development of new topical antioxidant formulations. Euryale ferox Salisbury (EF) is botanical name and it's pharmaceutical name is EURYALES SEMEN (ES). The stems and branchs of EF have been used as a traditional herbal medicine for the treatment of dysentery, diarrhea, leucorrhoea, incontinence and paralysis of joint. In this study, the antioxidant activity of extract from EF was studied in vitro methods by measuring the antioxidant activity and free radical scavenging activity by TEAC and DPPH, measuring the scavenging effects on reactive oxygen species (ROS) [superoxide anion, hydroxyl radical] and on reactive nitrogen species (RNS) [nitric oxide and peroxynitrite] as well as measuring the inhibitory effect on $Cu^{2+}$-induced human LDL oxidation. The EF extracts were found to have a potent scavenging activity, as well as an inhibitory effect on LDL oxidation. In conclusion, the EF extracts have antioxidative effects in vitro system, which can be used for developing pharmaceutical drug against oxidative stress and chronic degenerative disease such as atherosclerosis.

The purpose of this study is to classify species and correct misidentification of cacti (Opuntia) in Jeju area through morphological characteristics comparison. As a result of the study, it was found that Opuntia ficus-indica and O. ficus-indica var. saboten, which has been reported to grow naturally in Jeju Island, is Opuntia stricta. In the morphological comparison of species, it was confirmed that O. stricta showed clear differences in plant size, cladode shape, color of flowers and fruits, and characteristics of areole compared to the existing reported species. Based on the research results, the scientific name of Jeju cactus was corrected as Opuntia stricta, and the Korean name 'Hae-an-sun-in-jang' was newly named. Furthermore, it was suggested that various research literatures and national biodiversity management organizations need to confirm and correct the misidentification of species.

Objectives: This pilot study was carried out with the purpose of suggesting a methodology on mapping and registering Korean medicinal material concepts at 2011AB of the UMLS. Methods: 411 medicinal material concepts were mapped to biomedical terminology within the metathesaurus of the UMLS. Based on the forms of listing on the UMLS and thesauri information, the medicinal material concepts were classified into three groups and mapped. Results: 76 concepts in Group 1 which English CUIs have Chinese AUIs were mapped considering scientific names and Chinese strings. 259 concepts in Group 2 that have CUIs in the form of 'botanical name/Chinese pinyin' were mapped with the information of Korean and Chinese Pharmacopoeias. Groups 3, 76 concepts of English names in the Korean Pharmacopoeia are matched considering their botanic names and used parts. Conclusion: This study suggested a methodology to map Korean medicinal material concepts to international standard terminology, which will help ensure interoperability and compatibility between traditional medicine terminology and the UMLS.

Two unrecorded alien plants, Melilotus officinalis (L.) Lam. and M. indicus (L.) All. (Leguminosae) were found in Korea. M. officinalis is native to Eurasia and widely distributed in agricultural regions throughout the world. M. indicus is native to Mediterranean and Southwestern Europe, and naturalized in temperate regions all over the world. These species are morphologically similar to M. suaveolens (Jeon-dong-ssa-ri). However, M. officinalis is distinguished from M. suaveolens by transverse nerved legumes, definite ovary stalks, and five to eight number of ovules in ovary. M. indicus is also distinguished from M. suaveolens by smaller size of flowers, broadly triangular calyx teeth, globose legumes, and minutely papillose seeds. The local name of M. officinalis and M. indicus were given as "Ju-reum-jeon-dong-ssa-ri" and "Jom-jeon-dong-ssa-ri" based on transverse nerved legumes and overall smaller size than M. suaveolens, respectively. The descriptions on morphological characters and photographs at the habitat of M. officinalis and M. indicus are provided.

Stellaria sessiliflora Y. Yabe (Caryophyllaceae), which is known to be distributed throughout Japan excluding Okinawa, was recently found on Jeju Island in Korea. Reports on the Japanese flora state that this species is distributed on Jeju Island, and a photograph of one specimen (Slide No. 6294) collected from Jeju Island by Ohwi in May 1935 confirms this. Additionally, specimens at the National Arboretum and Korea Forest Research Institute indicate that S. sessiliflora has occurred on Jeju Island for a considerable amount of time. However, the species has never been officially listed in the flora of Korea. Stellaria sessiliflora is distinguished from S. media by having broader leaves with a slightly undulate margin, petiolate leaves on the upper part of the stem, and 10 stamens. The local name 'Geu-Neul-Byeol-Kkot' is given to the species based on its shady habitat under deciduous broadleaf forest. Details of the morphological characters, an illustration, the type specimen, voucher specimen data, and photographs of Stellaria sessiliflora in Korea are presented.

The Smilacis chinae Radix refers to the root of Smilax chinae L distributed in mountain and filed of Korea, and it is a vine shrub in the Lilaceae family, called Berchemia berchemiaefolia, and is referred to as Smilacis chinae Radix in it's a natural medicine name. Antibacterial, inflammatory, and antioxidant activity were studied in Smilacis chinae Radix. In this study, biological activities such as antioxidant (DPPH, ABTs, TPC), cytotoxicity, wrinkle improvement, and whitening improvement to increase the utilization value of Smilacis chinae Radix and identify the botanical value. Therefore, we tried to explore the applicability of Smilacis chinae Radix as a functional cosmetic material. Smilacis chinae Radix (SCR) was dried and extracted with ethanol. In order to measure the biological activity of the SCR, antioxidant activity, inhibition activities of collagenase, tyrosinase and cell viability were measured. The DPPH (1,1-diphenyl-2-picryl hydrazyl) radical scavenging activity in the extract with a concentration of 400㎍/mL is 91.22% ± 0.41%%. ABTs (2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity in the extract with a concentration of 400㎍/mL is 99.60% ± 0.03%. Total polyphenol contents (TPC) are 0.203 ± 0.05 mg GAE/mg Ext when SCR was lmg/mL. And the Cell viability for HaCaT derived human keratinocyte and Raw264.7, a mouse-derived macrophage was determined using the MTT assay. When cell was treated with 100㎍/mL of SCR, HaCaT cell showed cell viability of 78.09 ± 0.1% and Raw264.7 cell showed cell viability of 91.88 ± 0.42%. From the above results, we have shown the possibility that the CSR have antioxidant ability, inhibition activity of collagenase and tyrosinase and cell safety ability which can be useful in a functional cosmetic material.
