LLE works by relying on immiscibility between two liquids with the solvents having varying degrees of solubility constants on the solutes. If most terpenes are not as soluble in water methanol mix (which is what I am hypothesizing) then the molecules will stay in the “organic” (hexane layer). I would love to explain my doubt over the phone cuz these messages are a little lengthy to type.
