I would suggest you evap heptane until it becomes supersaturated (murky). Then SLOWLY let it cool under the room temp (a couple of hours would do) then put in it a fridge for half a day, then put in in a freezer for another 6 hours. Decant the heptane and store it for future use.
Dry the remaining gooey spice and oils precipitate completely.
Do a simplified quick A/B on the precipitate. Always worked for SWIM.
P.S. If your extract is very dirty re-xtallisation is not very efficient.
Do not seek the truth, just drop your opinions.
