Five phenolic compounds were isolated from the whole plants of Juncus diastrophanthus (Juncaceae) through repeated column chromatography. Their chemical structures were elucidated as methyl 3,5-di-O-caffeoylquinate (1), luteolin-7-O-β-D-glucopyranoside (2), methyl 4,5-di-O-caffeoylquinate (3), quercetin-3-O-β-D-arabinopyranoside (4), and methyl 3,4-di-O-caffeoylquinate (5) by spectroscopic techniques. These compounds were isolated for the first time from this plant.

한국산 골풀속(골풀과) 식물들의 식별 형질

김성민,김상태 한국식물분류학회 2013 식물 분류학회지 Vol.43 No.3

As a recent infrageneric classification of Juncus (Juncaceae), Kirschner suggested two subgenera which are distinguished by the type of inflorescence and the absence/presence of bracteole along with 10 sections which are distinguished by the characters of the leaves, the position of the inflorescence, and types of stamens and seeds. However, an intensive morphological investigation on Korean Juncus has yet to be performed. We surveyed the morphological characters of 14 taxa distributed throughout the Korean peninsula, including one North Korean taxon. The quantitative and qualitative characters of rhizomes, leaves, inflorescences, flowers, fruits, and seeds were investigated on each taxon using about 950 specimens of Korean Juncus on loan from major Korean herbaria. As a result, we provide diagnostic characters with illustrations and a key to Korean Juncus. 전 세계 Juncus (골풀속)의 속내 분류체계는 최근 Kirschner에 의해 2아속 10절로 정리된 바 있으며, 두 아속은 소포의 유무와 화서에 의해 구분되며, 각각의 절은 잎의 특징, 화서의 위치, 수술, 종자의 형질 등에 따라 구분된다. 현재까지 한국산 Juncus 분류군들을 구분하는 형질들에 대한 종합적 검토는 미흡한 상태이다. 그러므로 본 연구는 지금까지 한반도에 자생한다고 보고된 분류군들 중 채집 및 표본조사가 가능한 14개의 Juncus 분류군들에 대하여 국내 11개 표본관으로부터 약 950점의 표본을 대여하여 조사하였고, 이들에 대한 지하경, 잎, 화서, 꽃, 과실, 종자 등의 외부형태학적 형질들에 대한 형질상태의 유형을 파악하여 도해하고, 분류군들 간의 구분성을 검토하였다. 이를 바탕으로 주요 식별 형질들을 이용한 검색표를 제시하였다.

Antioxidative Phenolic Compounds from the Whole Plant of Juncus diastrophanthus

Saerom Park,Seokwon Yang,Dalrea Ahn,Jae Heon Yang,김대근 한국응용생명화학회 2011 Applied Biological Chemistry (Appl Biol Chem) Vol.54 No.5

Methanol extract of Juncus diastrophanthus (Juncaceae) was found to show potent antioxidant activity. Subsequent activity-guided fractionation of methanol extract of J. diastrophanthus led to the isolation of seven flavonoid compounds, isorhamnetin-3-O-α-L-rhamnopyranosyl(1→6)-β-Dglucopyranoside,narcissin (1), quercetin-3-O-α-L-rhamnopyranosyl(1→6)-β-D-glucopyranoside,rutin (2), kaempferol-3-O-α-L-rhamnopyranosyl(1→6)-β-D-glucopyranoside (3), quercetin (4), quercetin-3-O-α-L-rhamnopyranoside, quercitrin (5), quercetin-3-O-β-D-xylopyranoside (6), and luteolin (7). These compounds were isolated for the first time from this plant. Compounds 4 and 7 showed significant antioxidative effects on 1,1-diphenyl-2-picrylhydrazyl, and compound 5 showed significant riboflavin-originated superoxide and xanthine-originated superoxide quenching activities.

윤경원,조현,김무열 한국식물분류학회 2014 식물 분류학회지 Vol.44 No.4

A new species, Juncus baekdusanensis M. Kim (Juncaceae), has been named and described from Mt. Baekdu of the Korean peninsula. Juncus baekdusanensis shares several characters (terete leaf blades with leaf sheath auricles, between 1 and 2 flowered inflorescences, and 2 bracteoles) with its related species J. tenuis Willd. It is, however, distinct from J. tenuis which have 1-flowered inflorescences, green perianth, lanceolate perianth segments, acuminate perianth apexes, small capsules, and lowland grassland habitats by having 2-flowered inflorescences, reddish green perianth, ovate perianth segments, acute perianth apexes, large capsules, and highland swamp habitats.

New records of two alien plants, Juncus torreyi (Juncaceae) and Egeria densa (Hydrocharitaceae) in Korea

정종덕,나혜련,이규송,최영민,조웅래,현진오 한국식물분류학회 2023 식물 분류학회지 Vol.53 No.1

Naturalized populations of two alien plants were newly found, and we describe their morphological characteristics and habitats with photographs. One is a member of Juncaceae, Juncus torreyi Coville, and was newly found at a pool of a beach in Gangwon-do. This rush is native to North America and belongs to the sect. Ozophyllum (subgen. Juncus) according to certain morphological characteristics, such as its racemose inflorescence, the absence of floral bracteole, and unitubular leaves with perfect septa. J. torreyi is easily distinguishable from Korean rushes by its long rhizomes with swollen nodes and globular head with 25–100 flowers. Its introduction into Japan and Europe was reported, but the ecological risk associated with its over-dispersal is not known. The other alien plant is a submerged plant, Egeria densa Planch. (Hydrocharitaceae), which was found in streams in Gyeongsangbuk-do and ditches in the Busan-si area, both of which being in the watershed of the Nakdong River. Egeria densa is similar to Hydrilla verticillata (L.f.) Royle, which is native to Korea. However, it is distinguished from H. verticillata by its larger flowers and lack of overwintering organs. This alien plant is native to South America and was introduced for aquarium gardening and naturalized around the world. Egeria densa is treated as a malignant weed due to its asexual reproduction and rapid growth. Size changes and the number of populations of E. densa must be investigated.

Antioxidative Phenolic Compounds from the Whole Plant of Juncus diastrophanthus

Methanol extract of Juncus diastrophanthus (Juncaceae) was found to show potent antioxidant activity. Subsequent activity-guided fractionation of methanol extract of J. diastrophanthus led to the isolation of seven flavonoid compounds, isorhamnetin-3-O-${\alpha}$-L-rhamnopyranosyl(1${\rightarrow}$6)-${\beta}$-D-glucopyranoside, narcissin (1), quercetin-3-O-${\alpha}$-L-rhamnopyranosyl(1${\rightarrow}$6)-${\beta}$-D-glucopyranoside, rutin (2), kaempferol-3-O-${\alpha}$-L-rhamnopyranosyl(1${\rightarrow}$6)-${\beta}$-D-glucopyranoside (3), quercetin (4), quercetin-3-O-${\alpha}$-L-rhamnopyranoside, quercitrin (5), quercetin-3-O-${\beta}$-D-xylopyranoside (6), and luteolin (7). These compounds were isolated for the first time from this plant. Compounds 4 and 7 showed significant antioxidative effects on 1,1-diphenyl-2-picrylhydrazyl, and compound 5 showed significant riboflavin-originated superoxide and xanthine-originated superoxide quenching activities.

Cytotoxic and anti-inflammatory activities of phenanthrenes from the medullae of Juncus effusus L.

Wei Ma,Yue Zhang,Yun-Yun Ding,Feng Liu,Ning Li 대한약학회 2016 Archives of Pharmacal Research Vol.39 No.2

Bioactivity guided phytochemical investigation of the ethanol extract of the medullae of Juncus effusus resulted in the isolation of two new phenanthrenes, 8-hydroxymethyl-2- hydroxyl-1-methyl-5-vinyl-9,10-dihydrophenanthrene (1), and 5-(1-methoxyethyl)-1-methyl-phenanthren-2,7-diol (2) together with 15 known phenanthrenoids (3–17). The chemical structures of 1 and 2 were established by a combination of spectroscopic techniques. Compounds 1–15 and 17 were evaluated for their cytotoxic activities against five human cancer cell lines (SHSY-5Y, SMMC-7721, HepG-2, Hela and MCF-7) by CCK-8 assay, and their anti-inflammatory activities were also evaluated by inhibition on NO production in LPSactivated murine macrophage RAW 264.7 cells.
