removal of DMSO from plant extract

[Dr Omar Hamarsheh]

Dear Colleagues,

we are trying to evaporate DMSO from plant extract before being used for
purification in silica gel column. we tried to use rotary evaporator at 65
C for 3 hours, but seems residual DMSO still existed. colleagues suggest to
put the sample in freezer for 2 two days and them material
will precipitate.
I'll be so grateful for new ideas to remove DMSO.

thanks in advance,
