김동휘,성정숙,김명석,박춘근,박희운 韓國藥用作物學會 2006 한국약용작물학회지 Vol.14 No.3

중국에서 도입된 우슬 (Achyranthes bidentata.)을 신소득작물로 개발하기 위하여 국내 적응성을 검토하였다. A. bidentata는 25℃와 15℃에서 파종 후 각기 3일과 5일경부터 발아가 시작되었고, 10일과 15일경에는 대부분의 종자가 발아하였으며, 발아율과 발아세 모두 A. japonica보다 높게 나타났다. 초기생육 및 정식 후 60일까지는 A. bidentata의 생육이 A. japonica보다 양호하였으나, 그 후부터는 반대의 양상을 보였다. A. bidentata의 개화기와 낙엽기는 7월 10일과 9월 26일로 A. japonica에 비하여 월등히 빠르게 나타났다. A. japonica는 줄기색이 녹색 바탕에 옅은 자색을 띠는데 반하여 A. bidentata는 자색을 나타내어 두종 간의 차이가 확실하였다. A. japonica의 키와 분지수는 A. bidentata에 비하여 길고 많으나, 화방군의 길이와 화방군당 꽃수는 짧고 적었다. 뿌리의 길이, 직경, 지근수 및 천립중은 A. bidentata가 A. japonica에 비하여 짧고, 굵고, 적고, 무거운 것으로 조사되었다. A. bidentata의 수량성 (수원, 나주지역 평균)은 A. japonica와 비슷하였으며, A. bidentata는 A. japonica에 비교하여 수원보다 나주지역에서 수량 증수효과가 더욱 큰 것으로 보아 도입종인 A. bidentata의 재배적지는 따뜻한 남부지역으로 판단되었다. 이상의 결과로 한약재 우슬로 대한약전에 새로 수재된 도입우슬의 국내 재배생산 가능성이 확인되어 새로운 한약재 자원식물로 이용 가능할 것으로 기대된다. Achyranthes bidentata was recorded to new medicinal crop in a revised 8th edition of the Korean pharmacopoeia. Therefore, A. bidentata began to use for same purpose with Achyranthes japonica which was cultivated since old times in Korea. This study was conducted to investigate the adaptability of A. bidentata in Korea. The germination rate and speed of A. bidentata seeds were higher than those of A. japonica in 15℃ and 25℃. The growth of A. bidentata was greater than that of A. japonica until the 60 days after transplanting, but growth after that was the opposite. There were remarkable differences between two species in growth characteristics such as flowering date, leaf fall date, plant height, stem color and no. of branches. The flowering and leaf fall date of A. bidentata were earlier than A. japonica by July 7 and September 26. The plant height and number of branches of A.japonica were longer and more than A. bidentata, but the cluster length and no. of flowers per cluster of that were shorter and fewer than this. Number of supporting roots of A. bidentata and A. japonica was 10.7 and 14.6 per plant, respectively. The average yield was not different between two species. The yield of A. bidentata was 166 kg/l0 a in Suwon and 309 kg/10 a in Naju of Korea. The suitable cultivation region of A. bidentata was judged to southern area of Korea.

Content of 20-Hydroxyecdysone in Achyranthes japonica (roots) and Protaetia brevitarsis (larvae)

Seung Cheol Han,Jong Eun Lee 한국응용곤충학회 2024 한국응용곤충학회 학술대회논문집 Vol.2024 No.04

Ecdysteroids were first discovered in silkworm larvae in 1954 and are known to act as molting hormones in insects. Recently, biologically active phytoecdysone has gained increasing interest as it affects many physiological functions in mammals and has been reported to have a wide range of pharmacological properties such as protein synthesis and anticancer. 20-Hydroxyecdysone is a class of ecdysteroids commonly found in plants and animals and is known to stimulate antibody formation in humans, reduce cholesterol levels, and exert anabolic and blood sugar-lowering effects. In order to determine the content of 20-Hydroxyecdysone in Achyranthes japonica (roots) and Protaetia brevitarsis (larvae), which are known to have related benefits, we wanted to confirm their value as medicinal ingredients. The results of the analysis showed 0.0389 ug/g for Protaetia brevitarsis and 4.36 ug/g for Achyranthes japonica. These results confirm that plants secrete high concentrations of ecdysteroids to prevent insect damage, and are expected to be used as a basis for future research on the extraction of 20-Hydroxyecdysone for biological control and pharmacological use.

<P>There is increasing interest in phytoecdysteroids (PEs) because of their potential role in plant defense against insects. To understand the mechanism regulating their levels in plants, the fluctuation, distribution, and biosynthesis of PE 20-hydroxyecdysone (20E) examined in <I>Achyranthes japonica</I>. The total amount of 20E per individual plant initially remained at a constant level, and increased markedly after the first leaf pair (LP) stage, while the concentration of 20E in a given plant decreased rapidly during vegetative growth. In addition, the incorporation of [2-<SUP>14</SUP>C]-mevalonic acid into 20E did not differ significantly depending on plant organs and developmental stages, suggesting that biosynthesis of 20E is not restricted to particular organs or growth stages.</P>

서수정(Soo Jung Seo),김남우(Nam Woo Kim) 한국식품영양과학회 2014 한국식품영양과학회지 Vol.43 No.7

This study was conducted to investigate the physiological characteristics of water and ethanol extracts from leaves and stems of Achyranthes japonica. The highest contents of total polyphenol and flavonoid compounds were 58.27 and 42.22 mg/g in water extract from leaves, respectively. The protein content was the highest at 16.42 mg/g in water extract from leaves. Ethanol extract from stems showed the highest content of reducing sugars at 11.35 mg/g. In the measurement of electron donating ability (EDA), ethanol extract from stems showed the highest EDA at 93.41% at a concentration of 1.0 mg/mL. Superoxide dismutase-like activity of ethanol extract from leaves was the highest at 8.13% at a concentration of 1.0 mg/mL. In the analysis of nitrate scavenging activity, water extract from leaves showed the highest activity at 94.90% at pH 1.2, and the activity increased as concentration increased and pH decreased. In the measurement of xanthine oxidase inhibition, ethanol extract from stems showed the highest inhibitory activity at 66.67% at a concentration of 1.0 mg/mL. Especially, nitrate scavenging activities of water extract from leaves were the highest under all pH conditions. These results verify that extracts from leaves of A. japonica have strong antioxidant activity and can be used as an effective antioxidant source for nutraceutical foods, medicines, and cosmetic stuffs.

한상배,Chang Woo Lee,Yeo Dae Yoon,Jong-Ho Lee,강종순,Ki Hoon Lee,Won Kee Yoon,이기호,Song-Kyu Park,김환묵 대한약학회 2005 Archives of Pharmacal Research Vol.28 No.8

An oriental herbal combination (BDX-1) was isolated from Achyranthes bidentata and Atractylodes japonica. We previously tested the clinical effectiveness of BDX-1 in rheumatoid arthritis (RA) patients and found that it has a beneficial therapeutic effect. Here, we provide experimental evidence for the effectiveness of BDX-1 on RA in murine models. The oral administration of BDX-1 was found to markedly inhibit collagen-induced arthritis, adjuvant-induced arthritis, and zymosan-induced inflammation. It also inhibited carrageenan-induced acute edema and acetic acid-induced writhing response. In addition, the biological activity of BDX-1 was found to be strongly increased by fermentation. Our results suggest that BDX-1 could be useful for the treatment of rheumatoid arthritis.

엄미선(Mi-Sun Um) 한국응용과학기술학회 (구.한국유화학회) 2021 한국응용과학기술학회지 Vol.38 No.5

본 연구는 화장품 소재로서 우슬(Achyranthes japonica Nakai)의 가능성을 확인하기 위한 것이다. 우슬 추출물이 가지고 있는 항산화, 항염증, 항주름 효과를 측정하였다. 각각의 식물 재료는 70% 에탄올을 이용하여 우슬 뿌리(Achyranthes japonica Nakai roots, AJNR)와 우슬 줄기 (Achyranthes japonica Nakai stalks, AJNS)로부터 추출하였다. RAW 264.7 세포를 배양하여 추출물의 Nitric oxide assay를 진행하였고, 섬유아세포 CCD-986sk를 배양하여 추출물의 MMP-1 assay, Type I procollagen synthesis assay를 실시하였다. 이 연구의 결과, 항산화 활성은 우슬 뿌리와 우슬 줄기 모두 우수하였고, 뿌리는 함염증 효과가 월등하게 우수하였으며 줄기는 뿌리에 비해 MMP-1 저해 활성과 Type I procollagen 합성 효과가 조금 더 높았다. 이 연구의 결과, 우슬 뿌리와 우슬 줄기의 항산화 활성은 유사한 수준으로 우수하였고, 뿌리의 함염 활성은 줄기보다 월등하게 높았다. MMP-1 저해 활성과 Type I procollagen 합성 효과는 대체적으로 우수하였는데 줄기가 뿌리에 비해 가 조금 더 뛰어났다. 그러므로 우슬은 항산화, 항염증, 항주름의 활성을 갖는 기능성 화장품 소재로서 활용이 가능할 것으로 판단된다. The aim of this study was to assure the possiblility of Achyranthes japonica Nakai for a cosmetic material. For this we examined the Anti-oxidation, Anti-inflammation, Anti-wrinkle effects of Achyranthes japonica Nakai extract. Each material is extracted from Achyranthes japonica Nakai roots(AJNR) and Achyranthes japonica Nakai stalks(AJNS) using 70% ethanol. We carried out Nitric oxide assay of the extract with cultured RAW 264.7 macrophage cells, And we conducted MMP-1 assay, Type I procollagen synthesis assay of the extract with cultured CCD-986sk fibroblast cells. After we measured ABTS+ assay and SOD assay of AJNR and AJNS, we knew that effect of anti-oxidant increased as their concentration get higher. The result of this study was that the antioxidant activity of AJNR and AJNS was similarly excellent and the anti-inflammatory activity of AJNR was significantly higher than AJNS. The MMP-1 inhibitory activity and Type I procollagen synthesis of AJNR and AJNS was generally excellent, AJNS had slightly better than AJNR. Therefore I thought it has the chance to play an imfortant role as a functional cosmetic material for anti-oxidant, anti-inflammation and wrinkle reduction effects.

Evaluation of Achyranthes japonica Ethanol Extraction on the Inhibition Effect of Hyluronidase and Lipoxygenase

Kyung-Soon Cho(조경순) 한국생명과학회 2015 생명과학회지 Vol.25 No.12

우슬(牛膝)은 비름과(Amaranthaceae)의 쇠무릎(Achyranthes japonica)의 뿌리를 약용으로 한방에서 사용하고 있다. 1, 1- diphenyl 2-picrylhyorazyl (DPPH)은 잘 알려진 자유 라디칼이다. Hyaluronidase (HAase)은 결합조직의 세포외성 기질에서 히알루론산분해에 관여하는 효소이다. Lipoxygenases (LOX)은 지방산 대사와 면역에 중요한 역할을 수행한다. 본 연구에서는 쇠무릎에서 이 세 작용을 에탄올 추출물을 사용하여 생육 발달 단계(어린 영양기관과 성숙한 영양기관)에 대해 이들 추출물의 활성을 비교 조사하였으며 각 항목에 대해 50% 저해(IC50)의 농도를 산출하였다. 항산화 활성은 잎과 줄기, 뿌리 모두에서 탁월되었다. 특히 히알루로니다아제의 저해작용이 현저하였으며 향후 어떤 화합물인지 심도 있는 연구가 필요하다고 판단되었다. DPPH에 대한 항산화 활성과 LOX에 대한 저해작용은 기존 연구자의 결과와 유사하였다. 어린 식물조직과 성숙한 식물조직에서 추출한 발달 단계에 따른 이들 세 가지 활성에서 어린 뿌리보다 성숙한 뿌리에서 약간 더 우수한 작용을 보였으나 통계적으로 유의한 차이가 없었다. The 1, 1- diphenyl 2-picrylhyorazyl (DPPH) is a well-known radical and a trap (scavenger) for other radicals. Hyaluronidase (HAase) is an enzyme that depolymerizes the polysaccharide hyaluronic acid (HA) in the extracellular matrix of connective tissue. Lipoxygenase (LOX) enzyme was reported to convert the arachidonic, linoleic and other polyunsaturated fatty acid into biologically active metabolites involved in the inflammatory and immune responses. The purpose of the present study is to evaluate plant extracts as sources of natural antioxidants and to examine whether Achyranthes japonica having significant DPPH, HAase and LOX inhibitory activity. The inhibitory effect of HAase by A. japonica was assayed using a Morgan microplate assay. The antioxidant activity of the A. japonica extracts was measured on the basis of the scavenging activity of the stable 1, 1- diphenyl 2-picrylhyorazyl (DPPH) free radical. DPPH scavenging activity of matured roots of A. japonica was evaluated at 4.0 mg/ml was 87.8% and that of young roots was 86.2% at same concentration. The roots of A. japonica showed maximum inhibition of HAase activity (IC50 = 27.7 μg/ml). The highest LOX inhibition was recorded in the root extract among three vegetative parts. Inhibition of HAase activity of roots may contribute towards the development of herbal medicines. Although percent inhibition of lipoxygenase by Achyranthes japonica for all young and matured groups for leaves, stems, and roots at different concentrations, there were not show a statistically significant difference (p<0.05).

윤명섭,양승현,최훈 한국응용생명화학회 2022 Journal of Applied Biological Chemistry (J. Appl. Vol.65 No.1

A new rapid and simple method for metalaxyl in Atractylodes macrocephala Koidzumi and Achyranthes japonica Nakai has been developed and validated. This study was conducted to develop a method for analyzing metalaxyl by a method based on QuEChERS using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Samples were extracted with acetonitrile and purified using amino-propyl (NH2) Solid Phase Extraction cartridge. The method limit of quantitation (MLOQ) was 0.01 mg/kg. The linearity of matrixmatched calibration curve (r2) was ≥0.99 at the calibration range of 0.001-0.05 mg/kg. For recovery test, Atractylodes macrocephala Koidzumi or Achyranthes japonica Nakai was treated with standard solutions at MLOQ and 10MLOQ levels. Recovery rates were in the range of 88.1-109.1% with <5.5% coefficient of variation. This established analytical method was fully validated. Based on these results, it can contribute to improving the safety of residual pesticides in Atractylodes macrocephala Koidzumi and Achyranthes japonica Nakai.
