The isoflavone content of natural pastures in the county of Cordoba has been studied. Soil factors can induce variations in the phytoestrogen level in the pasture. Soil organic matter, pH and Ca increments are de¬terminants ...

The level of oestrogenic isoflavones (biochanin A, formononetin, genistein and pratensein) are determined on twenty species of the Trifolium genus. These samples have been taken from the natural pasture growing in the ...

The authors study the seasonal evolution of oestrogenic isoflavones in natural pastures in the province of Cordova. The highest proportion of positive samples corresponds to the spring with values approaching 80 p.100 of ...

After meassuring several dimensions of C. ladanifer it is concluded that they are not affected by different soil conditions (altitude,orientation, slope,..depth, texture and color). Perhaps accumulative, anthropic or ...
