Removing primuline from preparative TLC lipids ?

[noviceTLC]

Hello,
I would like to make preparative TLC to separate my glycolipid sample. The aim is to obtaine different glycolipid subfamillies (i.e. MGDG, DGDG, SQDG...) from an SPE fraction which contained MGDG, DGDG, or eventually SQDG...
I used primuline to detect non-destructively the lipids. However, I wonder about the primuline's presence in the different scrabed bands.
Do any one know how to remove primuline without modifying the separated lipids ?
I thank you in advance for your precious help.

Primulin is, apparently, the sodium salt of an aromatic sulfonic acid.
As such, I would expect a high level of solubility in water.
Do the lipids of interest have a high level of solubility in water.
YES or NO should suggest a method of removing the primulin.
