AMBERLITE™ XAD™4 is a polymeric adsorbent based on highly crosslinked, macroreticular polystyrene, aliphatic, or phenol-formaldehyde condensate polymers. It is used for recovery of high value materials, mainly for purification, decolorization, capture of pharmaceuticals and biopharmaceuticals and detergent removal. It is a white translucent beads, having 54 to 60 % moistire holding capacity and bead size, size between 0.49 - 0.69 mm. plant phenolics from aqueous extract can be extracted by using Amberlite XAD-2 resin.

You may try a strong ion exchange resin- please see:

 For separation of naturales compound, I propose to see the work of Daniil Olennikov. Success  https://www.researchgate.net/profile/Daniil_Olennikov

And maybe our study

If you are trying to separate phenolics using aqueous alcoholic extract then depending on percent of alcohol (methanol/ethanol) separation will be affected. As you are using a reversed phase resin, the higher percent of alcohol will not allow sufficient binding and a mixture will be obtained. Try to minimise the percent of alcohol while loading or if you are loading only aqueous extract then try to modify the elution pattern with increase in concentration of alcohol in water (use first the step gradient).

Dear Prakash

Pl. check the following.

Good luck.
