This study provides the first broad-scale investigation on the spatial and temporal occurrence of phytoestrogens and mycotoxins in streams in the United States. Fifteen stream sites across Iowa were sampled five times throughout the 2008 growing season to capture a range of climatic and crop-growth conditions. Basin size upstream from sampling sites ranged from 7 km2 to > 836,000 km2. Atrazine ...

A successful attempt of using sodium salt of a water- insoluble larvicide, as an alternative to the use of solutions of such larvicides in acetone and water, for the larvicidal studies is made, in the present study biochanin - A an isoflavone isolated from the flowers of Dalbergia sissoides (grah) when assessed for larvicidal study as its sodium salt on the fourth instar larvae of Culex quinque...

In addition to soya-derived preparations, red clover-based dietary supplements have gained considerable interest as an alternative isoflavone (IF) source. While metabolism and bioavailability of the main IF from both sources have already been investigated, studies are still lacking on the biokinetic behaviour of IF, which are present in red clover in minor amounts. In the present pilot study, i...

An impurity, present in some samples of l-asparagine, gave genistein on acid hydrolysis. The contaminant (probably the glucoside of genistein) was metabolized by Mycobacterium phlei to genistein and prunetin.

Diets enriched in soy foods containing a high concentration of isoflavonoids are associated with a decrease in the incidence of several chronic inflammatory diseases. Studies with experimental models of diseases, such as atherosclerosis, suggest that these effects can be ascribed to the biological properties of the isoflavones. Since the isoflavones and tyrosine have structural similarities and...

Red clover, known for its estrogenic activity due to its isoflavones content (biochanin A, genistein, daidzein and formononetin), was inoculated with the arbuscular mycorrhizal fungus Glomus mosseae. Once the symbiotic fungus was well established, plants were harvested and we determined the root and shoot dry weight as well as the P-content. In roots and leaves the levels of biochanin A, genist...

The optimization of a high-performance liquid chromatographic method to determine three isoflavonoids (daidzein, genistein, and biochanin A) in the fruit of Psoralea corylifolia is developed and validated. Dried psoralea fruit powder is extracted with aqueous methanol followed by the hydrolysis of the analytes' conjugated glycosides with hydrochloric acid. The HPLC assay is performed on a rever...

In this study, centrifugal ultrafiltration coupled with high performance liquid chromatographymass spectrometry was utilized to screen and identify xanthine oxidase inhibitors from Puerariae flos extract. The experimental conditions of centrifugal ultrafiltration including xanthine oxidase concentration, incubation time, pH and temperature were optimized. At the optimum condition (xanthine oxid...

The air-dried leaves of Ixora finlaysoniana Wall. ex. Don ( family Rubiaceae) afforded a new dammarane triterpenoid named: 17β-dammara-1-one -20 ene-3β-3', 8'-dimethyloctanoate (1) together with two known saturated fatty acids capric (2) and palmitic (3) from the chloroform extract as well as three phenolic acids: gallic (4), caffeic (5), chlorogenic (6), six flavonols: Kaempferol 3-O--D-arabi...

Phytoestrogens are naturally occurring estrogenic compounds found in plants and plant products. These compounds are also known to exert cellular effects independent of their interactions with estrogen receptors. We studied the effects of the phytoestrogens phloretin, phloridzin, genistein, and biochanin A on Ca(2+) uptake into the cardiac muscle sarcoplasmic reticulum (SR). Genistein and biocha...
