Enzyme-linked immunosorbent assays in combination with semi-preparative high-performance liquid chromatography (HPLC) and analytical HPLC with mass spectroscopy in the selective ion monitoring mode were used for the determination of selected isoflavones, daidzein, genistein, biochanin A and their homologues, in 20 representatives of the Rutaceae family. Species belonging to five genera were studied, namely Citrus, Fortunella, Poncirus, Ruta and Severinia. The enzyme immunoassays used were based on polyclonal antibodies raised against isoflavonoid conjugates with bovine serum albumin (BSA), namely biochanin A-7-BSA, daidzein-7-BSA, daidzein-4′-BSA, genistein-7-BSA and genistein-4′-BSA. Aglycones as well as glycosides were detected, and methoxyisoflavones appeared to be more abundant than hydoxyisoflavones. The content of individual isoflavonoids ranged from 0 to 2.6 mg/kg (dry weight); the sum of all measured substances reached up to 5.9 mg. Copyright © 2007 John Wiley & Sons, Ltd.

The development of polyclonal antibody-based enzyme-linked immunosorbent assays (ELISA) for the determination of individual isoflavones, i.e. daidzein, genistein and biochanin and their homologues, is presented in this work. Isoflavone conjugates with bovine serum albumin were used as immunogens, coupled at the position C 7 and C 4' via a carboxy methyl spacer. The developed ELISAs are highly specific, I 5 0 values of the standard curves range between 0.3-1.2 ng/ml. The cross reactivities to oth...

Abstract Common emphasis of the fact that isoflavonoids are characteristic metabolites of leguminous plants sometimes leads to overlooking that the presence of isoflavonoids has been reported in several dozen other families. The spectrum of isoflavonoid producing taxa includes the representatives of four classes of multicellular plants, namely the Bryopsida, the Pinopsida, the Magnoliopsida and the Liliopsida. A review, recently published by Reynaud et al. [Reynaud, J., Guilet D., Terreux R., Lu...

Six new apiosyl-(1→6)-glucosyl isoflavones (1−6) and four known ones were isolated from the stems of Glycosmis pentaphylla. The structures of the new glycosides are 3‘,7-dihydroxy-4‘,5,6-trimethoxyisoflavone 7-O-(5-O-trans-p-coumaroyl)-β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside (1), 2‘,7-dihydroxy-4‘,5‘,5,6-tetramethoxyisoflavone 7-O-(5-O-trans-p-coumaroyl)-β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside (2), 2‘,7-dihydroxy-4‘,5‘,5,6-tetramethoxyisoflavone 7-O-β-d-apiofuranosyl-(1→6)-β-d-glucopyran...

A new isoflavan, (3R)-6,2‘-dihydroxy-7-methoxy-4‘,5‘-methylenedioxyisoflavan, hildegardiol (1), and two known flavonoids, 2-hydroxymaackiain (2) and farrerol (3), were isolated from the antifungal root extract of Hildegardia barteri. The pterocarpan 2 was largely responsible for the observed antifungal activity.

Abstract Several types of isoflavonoid-like immunoreactivity were detected in water-ethanolic extracts from Acca sellowiana (Berg) Burret, Psidium guajava L. and Psidium littorale Raddi (Myrtaceae) leaves. Chromatographic mobility of the immunoreactive substances was compared to that of authentic standards, revealing a spectrum of isoflavonoid metabolites in both genera. Aglycones as well as glycosides were detected, namely daidzin, genistin, daidzein, genistein, formononetin, biochanin A, prune...

Abstract Two variants of immunoassay for the determination of biochanin A (5,7-dihydroxy 4′-methoxy isoflavone), i.e., a radioimmunoassay (RIA) and an indirect ELISA, have been developed and evaluated. Both methods employ the same rabbit antiserum to a 7- O -carboxymethyl-5-hydroxy-4′-methoxyisoflavone-bovine serum albumin (BSA) conjugate. A 125 I-labeled hapten-tyrosine methyl ester (TME) conjugate was used as a radioligand for the RIA. The indirect ELISA uses immunogen-coated microtitration pl...

Several types of compounds with immunoreactivity similar to isoflavonoids were detected in water: ethanol extracts of leaves of Fortunella obovata Hort. ex Tanaka, Murraya paniculata Jack. and four Citrus species, namely C. aurantium L., C. grandis Osbeck, C. limonia Osbeck., and C. sinensis Osbeck (Rutaceae). The chromatographic mobilities of the immunoreactive substances were compared with those of authentic standards, revealing a spectrum of isoflavonoid metabolites in all plants studied. Aglyc...

Competitive enzyme-linked immunosorbent assays (ELISA) for the determination of isoflavones daidzein, genistein and biochanin were developed. Isoflavone conjugates coupled at positions C7 and C4' via a carboxymethyl spacer to bovine serum albumin were used as immunogens and also as coating antigens. Assay conditions, including concentrations of antisera and coating antigens, were optimized and the effect of reaction time, various blocking agents and organic solvents was investigated.

Plants and herbs have been used to induce abortions but there is very little published information describing the commonly used ones. The purpose of this report is to describe the herbal products used to induce abortions, and to enhance awareness and understanding of their toxic effects. A descriptive retrospective survey was conducted on the calls received by the Montevideo Poison Centre between 1986 and 1999 concerning the ingestion of herbal infusions with abortive intent. A total of 86 cases...

Genistein (4′,5,7-trihydroxyisoflavone) is naturally present in plants of the soy family and is known to have various pharmacological activities, such as anti-cancer, anti-diabetic, anti-oxidant, etc. The phytoestrogen is one of the major isoflavones found in some medicinal plants having anthelmintic properties. This review describes the putative role of genistein as an anthelmintic, which has been tested on some helminth parasites in vitro. Genistein has been shown to cause paralysis and altera...

Plants of the Amaryllidaceae family are known as producers of biologically active alkaloids. Besides these a variety of flavonoids, including flavones, chalcones and chromones, have been detected in the Amaryllidaceous plants. In this study, we have analysed 16 representatives of the family for the presence of isoflavonoids. The water/ethanolic extracts were analysed with HPLC-ESI-MS both without any pre-treatment and after immunoaffinity chromatography as a clean-up step. Four individual immuno...

Ethanolic extracts of 23 species of the Apiaceae family were analyzed for their flavonoid and isoflavonoid content, using the following methods: high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS); semi-preparative HPLC with Enzyme Linked Immunosorbent Assay (HPLC-ELISA); and immunoaffinity extraction (IAE). Rutin and quercetin-3-glucoside were the most abundant flavonoid glycosides and the most abundant flavonoid aglycone was apigenin. The isoflavonoids daidzein, gen...

Amidst the vast number of diverse secondary metabolites of plants, isoflavonoids occupy a special place due to the wide range of their biological activities. The literature deals extensively with the positive effect of these well-known phytoestrogens on human health, including cancer prevention and the mitigation of menopause symptoms, as well as with the potential risks associated with their consumption. Isoflavonoids have considerable importance for plants themselves, particularly in the defen...

Activity-directed fractionation and purification processes were employed to identify isoflavonoids with antioxidant and antimicrobial activities from Brazilian red propolis. Crude propolis was extracted with ethanol (80%, v/v) and fractioned by liquid–liquid extraction technique using hexane and chloroform. Since chloroform fraction showed strong antioxidant and antimicrobial activities it was purified and isolated using various chromatographic techniques. Comparing our spectral data (UV, NMR, a...

Isoflavonoids are a diverse group of secondary metabolites derived from the phenylpropanoid pathway. These compounds are distributed predominantly in leguminous plants and play important roles in plant–environment interactions and human health. Consequently, the biosynthetic pathway of isoflavonoid compounds has been widely elucidated in the past decades. Up to now, most of the structural genes and some of the regulatory genes involved in this pathway have been isolated and well characterized. N...
