If you are looking for cheap solution, easiest way is to use a silica gel column chromatography. Use the adsorbent as you use for thin layer chromatography, one that does not contain binders (gypsum). If you have a good TLC system in which are separated the materials, then use the TLC developing solvent as eluent. Often it is worth to take back something to the solvent or solvent mixture polarity. Such on a column is well be separated the individual components. It is used for a column in which a small overpressure can be established. It was not my job with phenylpropanoids, but I used more natural materials separation of success with this method.

The simplest process would be percolation followed by liquid liquid extraction. But the above mentioned processes are time consuming.
