  • Leguminosae plants are known for its phytoestrogen constituents which play a major role in the prevention of osteoporosis, cancer and heart disease. In this study, the estrogenic activity of 158 samples from 58 species, 3 subspecies and 10 varieties of Leguminosae plants growing in Korea was evaluated. An estrogen, 17β-estradiol was used as a reference compound, and the potency of each sample was expressed in relative efficacy (%) compared to that of the reference by a reporter gene assay using MCF-7 cells. As results, the estrogenic activity of methanolic extracts of Phaseolus vulgaris var. humilis, Sophora flavescens, Lespedeza × robusta, Indigofera pseudotinctoria, Maackia amurensis, Glycine soja, Wisteria floribunda, Robinia pseudoacacia, Astragalus sinicus, Pueraria lobata, Lespedeza maximowiczii var. tomentella, Trifolium repens and Crotalaria sessiliflora showed similar to or higher at 100 ㎍/ml than the positive control at 10 nM. These findings can be a potential evidence for developing estrogen alternatives resolving various types of menopause symptoms with information on proper harvest season and usage plant part. To the best of our knowledge, the estrogenic activity of Lespedeza × robusta, Indigofera pseudotinctoria, Wisteria floribunda, Robinia pseudoacacia and Lespedeza maximowiczii var. tomentella is reported for the first time in this study.

  • Phytoestrogens are considered to exhibit biological activities in human and animal. There are few data on the contents of phytoestrogens in woody plants. This study was undertaken to examine phytoestrogen contents in five species (Albizzia coreana, Albizzia julibrissin, Gleditsia japonica var. koraiensis, Maackia fauriei and Sophora japonica) of leguminosae. An HPLC method was employed for the first time to analyze phytoestrogens in five species. The contents of daidzein and genistein were in the range of 2.9~170.5 ㎍/g and 1.3~118.4 ㎍/g, respectively. Daidzein and genistein were most abundantly present in the Sophora japonica among the samples examined.

  • 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.

  • 최근 국내에서 2종의 싸리속(Lespedeza) 귀화식물을 발견하여 보고한다. 자주비수리(L. lichiyuniae)는 비수리(L. cuneata) 및 땅비수리(L. juncea)와 형태적으로 유사하지만, 꽃이 분홍 또는 홍자색이고 잎 뒷면과 폐쇄화 열매에 털이 밀생하는 점에서 구분된다. 한편 큰잎싸리(L. davidii)는 큰 소엽을 갖는 특징에 의해 국내 싸리속의 다른 종들과 구별되며, 같은 목본성 싸리아속 식물들로부터는 식물체 전체에 연모가 밀생하는 특징으로 식별된다. 국내에서 이 두 종은 새로 조성된 공원이나 도로변에서 발견된다.

  • 40종류 이상의 식물의 유식물체, 채소 그리고 가공식품의 글루타치온과 그의 산화형 글루타치온(GSSG)함량을 측정하였다. 유식물체를 이용한 실험에서 총글루타치온 함량은, 100 g(생체중)당 $0-120{\mu}mol$의 범위였으며, 같은 과, 종 및 품종에 있어서도 현저한 차이를 나타내었다. 특히, 시판되고 있는 곡물과 채소를 이용한 실험에서는 콩과의 팥과 강낭콩에서 높은 글루타치온 함량을 나타내었다. 콩을 이용한 가공식품(고추장, 된장, 간장 등)에서는 글루타치온 함량이 거의 검출되지 않았다. 식품에 있어서 고농도의 글루타치온은 식품의 높은 부가가치가 되리라 생각된다.

  • The n-butanol soluble fraction of the extract obtained from the whole plants of Ononis serrata afforded the pterocarpan derivative medicarpin-3-O-glucoside and the isoflavone glucoside rothindin. Structures were elucidated by chemical methods, detailed spectral analyses as well as comparison with the literature data.

  • Legumes are important agricultural and commercial crops characterized by root nodules formed as a result of the symbiotic relationship with nitrogen-fixing rhizobia. Due to the economic significance the chemistry of some of these species has been well recognized. Soybeans and processed soy products, which contain isoflavonoids and saponins, are of wide interest for their multifacted biological effects. (omitted)

  • From the 70% EtOH extract of the roots of Astragalus membranaceus (Leguminosae), fifteen saponins were isolated and identified as astragaloside I (1), isoastragaloside II (2), astragaloside II (3), agroastragaloside I (4), cyclogaleginoside B (5), cycloaraloside A (6), brachyoside B (7), agroastragaloside II (8), astragaloside III (9), astragaloside IV (10), astramembranoside A (11), astramembranoside B (12), cylocanthoside E (13), cyclounifolioside B (14) and azukisaponin V methyl ester (15) by spectroscopic methods. Ten compounds 1 - 3, 5 - 7, 9 - 11 and 14 have cycloastragenol as an aglycon, and four compounds 4, 8 , 12, and 13 have cyclocanthogenin as an aglycon. The hairy roots of A. membranaceus were shown to produce previously unreported cycloartane-type saponins such as agroastragalosides I (4) and II (8) and cycloastragenol $3-O-{\beta}-D-xyloside$ (5), together with the known saponins. This is the first report of these saponins (4, 5, and 8) from the intact plant. Although the occurrence of the oleanane-type triterpene saponin, azukisaponin V methyl ester (15), in Astragalus plants has been demonstrated by others, this is the first report of the azukisaponin V methyl ester (15) from the Astragalus plants.

  • Many of plants had been reported having immunostimulating activity. This study reports the immunostimulating activity of Cassia tora L. (Leguminosae) seed, by means of solvent extraction method. Ethanol extract and solvent fractions, n-hexane, chloroform, ethylacetate, n-butanol and aqueous layer of Cassia tora L. seed were tested for immunostimulating activity in vitro. The ethylacetate-soluble fraction caused significant inhibition on the production of nitric oxide by murine macrophages (RAW 264.7), and mouse splenocytes were also stimulated at the concentration of 10 pgfmL. Three anthraquinones, chrysophanol (1), isochrysophanol (2) and aloe-emodin (3) with immunostimulating activity were isolated from the ethylacetate-soluble fraction of Cassia tora L. seed through activity-monitored fractionation and isolation method. These results permit Cassia tora L. to be useful as one the of natural immunostimulating crops.

  • During our research program to find DNA strand-scission agents from higher plants, the MeOH extracts of the stems of Mucuna birdwoodiana Tutcher. (Leguminosae) exhibited the most potent activity with an $IC_{50}$ value of $4.9\;{\mu}g/ml$. Thus, detailed laboratory investigation was performed, and led to the isolation of known compounds, $({\pm})$-catechin (1) and (-)-epicatechin(2) as active principles. Compounds 1 and 2 showed significant activity of DNA strand-scission with $IC_{50}$ values of 10.8 and $7.5\;{\mu}g/ml$, respectively (positive control, bleomycin: $IC_{50}\;3.3\;{\mu}g/ml$.
