If you used too little NaOH you wouldn't have pulled anything.
Right after this first extraction I wanted to see if increasing the amount of NaOH would increase the yield so 75 g more of NaOH was dissolved into ~750 mL of additional water and added to the mix with 400 mL more of naphtha poured into the bowl which was stirred again for close to 30 minutes and carefully separated from the mix for evaporation. With the amount of NaOH doubled the yield was found to be 50% greater at 1.5 g of alkaloid and because of this I recommend a minimum of 150 g of NaOH for 2 L of water when extracting 250–500 g of broken root bark and from 200–250 g of this base per 3+ L of water when extracting from 500–1000 g of broken root bark.
The rule of thumb, for me, is put it in the freezer, it'll cloud up. Wait till it clears, at this point all the DMT that is going to precipitate at that temp & concentration is there.
Take it out of freezer, pour off Naptha, dry crystals.
Evaporate remaining Naptha til it starts to cloud, put back in freezer repeat as many time as necssary.
