Antisolvent is a solvent in which your compound is less soluble. Usually solvent/antisolvent mixture is a good component for obtaining crystals, especially in the case of organic compounds.
Thank you. But I like to know the meaning and examples for anti-solvent......
let me explain...if you take up say : Aqueous silver nitrate (AgNO3) which is to be added to a solution containing potassium chloride (KCl), the precipitation of a white solid, silver chloride is observed.... all the products of a reaction and the by-products of a reaction are termed to an anti-solvent....because the products formed are not soluble in the reactant solution...there may be certain cases where they may be...but i haven't come across....so sorry!

thank you sir.......... I expect more precise answer for this...... Please help me.......
as already suggested antisolvent, a solvent that causes precipitation when added to a solution in another solvent. You may also consult Wikipedia.
Two phase system means in this regard the solution and the component which gets insoluble by addition of the antisolvent.
As an example a polar substance dissolved in ethanol gets precipitated when the antisolvent xylene is added in sufficient amounts, though ethanol and xylene are miscible.
I think anti-solvent is referred to compound possessing very strong intermolecular interactions with it. Such interactions are not comparable with any solvent. Therefore, no salvation of such compound in common types of solvents.
sorry for this comment i understand the anti-solvent is a special case for crystallization.
