| an ecophysiological study of plants growing on the fly ash deposits from the "nikola tesla-a" thermal power station in serbia. | this ecophysiological research on the ash deposits from the "nikola tesla-a" thermal power station in serbia covered 10 plant species (tamarix gallica, populus alba, spiraea van-hauttei, ambrosia artemisifolia, amorpha fruticosa, eupatorium cannabinum, crepis setosa, epilobium collinum, verbascum phlomoides, and cirsium arvense). this paper presents the results of a water regime analysis, photosynthetic efficiency and trace elements (b, cu, mn, zn, pb, and cd) content in vegetative plant parts. ... | 2004 | 15503386 |
| new spirorotenoids from tephrosia candida. | the ethyl acetate extract of roots of tephrosia candida afforded three new spirorotenoids belonging to a new class of spirocompounds, named tephrospirolactone, tephrospiroketone i, and tephrospiroketone ii. the structures of these compounds were determined mainly based on spectral analysis. the only known spirorotenoid described in the literature is amorphispironone, isolated from amorpha fruticosa. | 2012 | 12132677 |
| review article number 135 biosynthesis in the rotenoid group of natural products: applications of isotope methodology. | using the natural rotenoids rotenone, amorphigenin, deguelin, rotenonic acid, dalpanol and munduserone as examples, their phytochemical biosynthesis has been examined in derris elliptica, amorpha fruticosa and tephrosia vogelii. the rotenoids are advanced isoflavonoids, and construction of their angular a&z.drule;b&z.drule;c&z.drule;d-ring systems has been studied experimentally starting out from simple primary metabolites and passing through a series of mainly oxidative phases. the oxidative re ... | 1998 | 11711058 |
| inhibitor of tumor necrosis factor-alpha production in lipopolysaccharide-stimulated raw264.7 cells from amorpha fruticosa. | certain flavonoids were reported to show an immunoregulatory activity against lymphocyte proliferation and cytokine production. in the course of a search for tumor necrosis factor (tnf)-alpha inhibitory compounds from natural plants, we also isolated a prenylfavanone type of flavonoid, amoradicin, from the extract of amorpha fruticosa by activity-guided fractionation. this compound significantly inhibited tnf-alpha production in lipopolysaccharide (lps)-stimulated raw264.7 cells with an ic(50) v ... | 2000 | 10771202 |
| antitumor agents, 138. rotenoids and isoflavones as cytotoxic constitutents from amorpha fruticosa. | eight cytotoxic compounds have been isolated from the chcl3 extract of amorpha fruticosa. one compound, 6'-o-d-beta-glucopyranosyldalpanol [10], is a new cytotoxic rotenoid. another known rotenoid, 12 alpha beta-hydroxyamorphigenin [6], was first shown to exhibit extremely potent cytotoxicity (ed50 < 0.001 microgram/ml) in six neoplastic cell lines. in addition to these compounds, three isoflavones (afrormosin [1], 7,2',4', 5'-tetramethoxyisoflavone [2], 8-methylretusin [3]) and five rotenoids ( ... | 1993 | 8326318 |

| isolation and identification of a cannabinoid-like compound from amorpha species. | the petroleum ether extracts from several plants have been screened on the plates with the chromogenic reagent fast blue b. salt. extracts from different plant parts of amorpha fruticosa, a. nanna, and a. canescens gave several spots with color and rf values similar to those of cannabis sativa extract. the major compound, amorphastilbol (1), was isolated by column chromatography, purified, and characterized by mp, elemental analysis, uv, ir, mass, prm, and cmr spectroscopy. further information w ... | 2006 | 521816 |
