Mindlusion said:...if it were me i might try recrystallizing in boiling IPA
I did this and it seemed to work without having to do the hexane, water, and IPA washes. However, my yield is 115mg from 85g of dry leaves (1.35 mg/g), which is half of gibran2's yield (not sure why).
I started with an off green residue after drying a 3x freezer cold acetone extract. This was re-X ed twice in boiling IPA (see small white xtals growing in the first picture) to get an off white powder (second picture).
I was expecting more like 250mg of yield . Gonna dry the IPA re-x solution and see if there is something there. Also, it seems that light can degrade salvinorin in solution and I was not careful about that. Finally, my leaves were collected before a frost and the plants had been in cold weather for a few weeks (not sure if that matters).
