Yes I wonder whether the 5% of toluene in sc#$eys shelly makes that much difference. I suppose it depends on the ratio to spice.

200ml would have 10ml of toluene which could hold maybe up to 100mg(?) however once saturated it wouldnt be held by the hexane as spice isnt very soluble at all in cool hexane. Maybe the whole is greater than the sum of its parts.

A test would be to dissolve a known ammount of spice and weigh how much precipitates the next day once its dry. The remainder could always be recovered by backsalting or evapping.
