Abstract: The present invention relates to extracts derived from plants and/or fractions thereof, compositions comprising same and use thereof in protecting tissues from damages caused by exogenous toxins. In particular, the present invention relates to polar extract and/or fraction thereof derived from Asteriscus graveolens, compositions comprising same and use thereof in protecting tissues comprising epithelial cell from the deleterious effect of exogenous toxins, particularly toxins originating from environmental pollution.

Abstract: A process for obtaining a solid soy isoflavone- and protein-containing isolate in which isoflavones constitute at least 7% of the isolate and are present in predominantly glycoside form, (genistin+genistein) constitute at least 50% of the isoflavones, the weight ratio (genistin+genistein):(daidzin+daidzein) is at least 1.5:1 and the bulk density is at least 0.57 g/ml. The process includes the sequential steps of (a) heating a soy soluble extract (SSE), made by aqueous alcohol extraction of defatted soy solids and evaporation of the alcohol, at acid pH and at a temperature within the range 70°-90° C. to cause sedimentation of an insoluble fraction containing saponin, trypsin inhibitor and isoflavone compounds; (b) cooling the mixture from step (a) to a temperature of not lower than 30° C. and separating the insoluble fraction from supernatant liquid in the mixture of step (a) at a temperature of not lower than 30° C.
