Is there a reason why one couldn't triturate into water, filter, and then lyophilize the filtrate?

Using less polar or non polar solvent such as dichloromethane

Of the extract is on solution,evaporate it until dryness (through liophillozation is the best option).after add water,warm slightly (40C) and solve it.then,surely you can separate the insolublebfraction by filtration.

Dear

The separation of phytochemicals is not that simple. The use of fractionation methodologies can give a good move to your target, but the polyphenolic compounds have high diversity in structure, so small amount will travel to each fractionation. You should use different solvents with gradual polarity e.g. Hexane, chloroform, ethyl acetate, butanol, water. You have to repeat the solvent several times before you go to the next one. However, you can use the column chromatography or liquid liquid extraction methodologies. The non polar phenolic compounds usually will concentrate in chloroform fractionation, the polar will appear in butanol and aqua fractions. This process will give you good start to isolate your target compounds.

Respected Sir,

    use to non-polar solvent like hexane solvent to separate water in soluble phenolic compound and further separate water soluble compound by using column chromatography method.

Thanks everyone for your contributions. I've used n-hexane & dichloromethane to drive out the pigments and fatty matter. The got the water-insoluble polyphenols in ethylacetate fraction.
