Firstly you can use the solvent with non-polar solvent. Following that, partial polar solvent. Finally you should use the polar one.

Dear sir

Non polar to polar is best..

Extraction of polyphenols from plant extracts is something my research group does quite frequently. We usually macerate exhaustively in 80% methanol first, flash evaporate the concentrate then freeze dry it. You may want to consider removing chlorophylls from your sample by mixing with dichloromethane (before flash evapourating)

But what you need to remember is that the extraction solvent used really depends on the target compounds you wish to isolate. 

Dear,  always go from non-polar to polar for proper and effective extraction
