Merck indicates that Gramine is practically insoluble in petroleum ether. This would mean that the last step in SWIMs 'all natural no heat spice tek' would be great to seperate the gramine, never did that TEK with Phalaris but in theory... check it out.
After your extraction (doesnt have to be the all natural TEK, since it's kinda lot of work) try to dissolve your endproduct in hot petroleum ether. This will dissolve a lot of spice, but very little Gramine. Then pour off your hot petroleum ether. It will first push out any oils and theoretically also any gramine that might went into the hot PE. When it is cooled down to room temperature or you see crystals forming pour off again and put in the fridge overnight. Gramine-free snowglobes should be there to wish you a perfect day.
Never thought of it or looked it up since, but would be a great and easy way to get a gramine free Phalaris spice. :d
My idea for an easy gramine-free Phalaris TEK would be: (follow the first steps of preferred STB) Soak Phalaris in vinegar for 3 days. Add NaOH and Limonene on top. Stir and seperate Limonene and repeat twice. Pull out alks from the Limonene with vinegar. Seperate vinegar and add NaOH till an oil forms. Add PE on top and heat up the whole thing while stirring. Pour off your PE and let it cool down till oils are pushed out. Pour off again in a fresh container and put it in the fridge overnight.
Now I'm thinking, this TEK would also be great for gramine free stuff like MHRB. Instead of adding NaOH to your vinegar after pulling from Limonene, just add Ammonia and let it dry. Or like in SWIMs TEK, pour throught cloth which will absorb the oily parts, dry and extract in ETOH, use for changa or let that dry. Shouldn't that give an good smokable product?
But, if Gramine is indeed not soluble in Limonene, we SWIM could just follow the TEK above and have a more complete Phalaris extract, since with the PE you get very clear crystals.
Good Luck and inform us of results!
