Athyrium acutipinnulum, called as Ulleungdo ladyfern (Seom-go-sa-ri), is a native plant of South Korea. A. acutipinnulum has been consumed as foods and also traditionally used for the treatment of epilepsy, gonorrhea and nerve disorder. The methanolic extract and EtOAc soluble fraction of A. acutipinnulum showed the antioxidant activity. Fractionation using various chromatographic techniques resulted in the isolation of 13 compounds. The structures were elucidated on the basis of spectroscopic methods as seven phenolic compounds, methyl 2-hydroxy-3-phenylpropanoate (1), protocatechualdehyde (2), caffeic acid (3), trans-p-coumaric acid (4), (-)-4-E-caffeoyl-L-threonic acid (5), 5-O-caffeoyl shikimic acid (6) and 5-O-caffeoyl quinic acid (7), three flavonoids, quercetin 3-O-β-glucoside (8), naringenin-7-O-β-glucoside (9) and sutchenoside A (10), two steroids, ponasterone A (11) and ecdysone (12) and a coumarin, esculetin (13). Among them, compounds 5 and 10 were first reported from Athyrium spp and compounds 2, 5, 6 and 7 showed the antioxidant activity.

The perennial edible wild plants such as Aster glehnii, Solidago virgaurea subsp. gigantean, Allium ochotense, Athyrium acutipinnulum, Aruncus dioicus var. kamtschaticus and Codonopsis lanceolata have cultivated as the main income crops introduced into the fields about 30 years ago in Ulleung island. Soil samples were collected from 190 fields and assessed the effects of management practices on soil chemical properties at wild edible plant fields under no-till system. The strong acidic soils of pH 5.4 or less were detected in 45% of the soil samples. The level of soil organic matter was being held at mean $63{\pm}28g\;kg^{-1}$, 2.7 times higher than upland soils in Korea. Available phosphate and exchangeable potassium showed more than recommended levels of upland crops as $680{\pm}489mg\;kg^{-1}$ and $1.94{\pm}1.7cmol_c\;kg^{-1}$, respectively. The fields of Solidago and Aster showing strong soil acidity and high level of available phosphate and water soluble $NO_3{^-}$ were distinguished from other crops in analysis of variance and principal component analysis of soil chemicals. These results suggested that high frequency of acidic soil and high levels of available $P_2O_5$, exchangeable $K_2O$ and water soluble $NO_3{^-}$ were accompanied with the use of urea and NPK-fertilizer based on nitrogen in the field. However, further research is needed to understand the appropriate management of fertilization and the prevention of soil acidification for wild edible plants.

Objectives : The purpose of this research was total polyphenol contents, anti-oxidant activities, anti-inflammatory activities and anti-wrinkle activities of Ulleung islands plants for application as a cosmeceutical ingredients Methods : We were experimented total polyphenol contents, anti-oxidant activities, anti-inflammatory activity and anti-wrinkle activities. Results : In the physiological activities, most Ulleung islands plants is showed the highest anti-oxidant, anti-inflammatory activity in ABTS+ radical cation scavenging activity, hydrogen peroxide($H_2O_2$) scavenging activity, nitric oxide scavenging activity. All experiment of the water and ethanol extract from the Ulleung islands plants ingredients were gradually increased as well. Conclusions : These results suggest that extracts from Ulleung islands plants can be used in natural ingredient in food or cosmetic industry.

화산섬인 울릉도는 내륙과는 다른 기후, 토양, 지형 특성을 가지고 있으며, 농업 또한 차별화된 특징을 나타낸다. 본 연구에서는 울릉도 농경지에 출현하는 식물종의 종조성 및 그 특성을 밝히고자 하였다. 식물상 조사는 2016년 5월과 2020년 7월과 8월 총 3차례, 37개 지점에서 수행되었다. 그 결과, 울릉도 농경지에 출현하는 관속식물은 53과 132속 160종 14변종 5아종, 1잡종으로 총 186분류군으로 조사되었다. 과별 분포현황은 국화과가 가장 많은 33분류군을 차지하였고, 다음으로 벼과 25분류군, 마디풀과 12분류군, 콩과가 12분류군, 마디풀과 11분류군, 백합과 9분류군으로 나타났다. 울릉도 농경지에 출현하는 식물의 생활형 유형은 일년생식물-단립식물-중력산포형-직립형(Th-R₅-D₄-e)으로 나타났다. 희귀식물로는 섬고사리, 섬기린초, 섬나무딸기, 섬바디, 섬쥐똥나무, 섬쑥부쟁이, 물엉겅퀴, 섬말나리, 왕둥굴레 등 9분류군이 확인되었다. 생태계 교란 식물은 애기수영, 환삼덩굴 2분류군이 확인되었다. 귀화식물은 13과 33속 44종 1변종으로 총 45분류군이 확인되었고, 도시화지수는 13.9%, 귀화율은 24.2%를 나타냈다.
