theoretically you wouldnt need to boil for the salt method.. just make a long room temperature water infusion for a couple of days, filter, keep the water separately, add more water to the solids, repeat for a total of 3x.. then put together the 3x water, throw out solids, put the cold infusion in the fridge and let it decant overnight.. throw away precipitated solids, keep the liquid, add 36g of salt per 100ml of water, mix well, again let decant. throw away the top acqueous layer, add more fresh water (preferably warm) to the bottom precipitated layer, add base, let precipitate overnight again, then filter and keep solids which should be harmala alkaloids
thats how SWIM does it, he never did an A/B with rue but it should work also
Don't use hydrochloric acid (myriatic acid). Use acetic acid (vinegar). Harmala alkaloids are very poorly soluble in hydrochloric acid and can actually be precipitated from it causing a loss of yield. They are extremely soluble in acetic acid. All tests shows acetic acid is the best for harmala alkaloid extraction.
