afer a dit:
toxic alkaloids such as vasicine and vasicinone.
Wow that's something new to me, could you please provide some links on it?
well you should quote me completely.. the 'possibly' was important there
here's words from jonathan ott:
Syrian rue seeds also contain significant levels of the uterotonic quinazoline alkaloids vasicine (peganine) and vasicinone, accounting for ethnomedicinal use of these seeds as an abortifacient.(5,17,22) Since these alkaloids are much less soluble in water than are the B-carbolines, once again making an aqueous infusion will effect a separation, leaving the bulk of the quinazoline alkaloids behind in the seed residue, amounting to lower toxicity, especially significant for women, particularly if they are pregnant.

but im not sure about the part that says a water extraction will get rid of them.. I do know however, that different people have made chemical analysis of manske-extracted harmalas (if im not mistaken one was shulgin, the other a member of the Nexus), and they were completely clean of these 'other' alkaloids.
But dont get too worried about it, its more of a recomendation to women and in special pregnant women.. If you google vasicine/vasicinone you also see that they have certain medicinal properties too...
In any case, anecdotal evidence seems to suggest that extracting the harmalas diminishes nausea and other negative somatic effects, and not to mention the fact one can make a food safe extraction of harmalas (only need salt, water, vinegar and sodium carbonate which can be made by putting sodium bicarbonate in the oven).
The biggest problem of this extraction is the filtering, which is a pain. But one should not filter until the very last part..
How to extract harmalas from rue:
Grind harmalas, boil 3x vinegar, separate liquid throwing solids out. Decant in the fridge, throwing bottom sediments and keeping liquid. Saturate with salt (around 30g salt per liter water).. dont worry too much wont hurt, it will be eliminated afterwards.
Then decant again in the fridge overnight. Then this time whatever decants/precipitates is the alkaloids (in hcl salt form) and salt and oils and other 'contamination' (no prob). Throw out as much of the liquid as possible, and then add more fresh warm water to redissolve the harmala salts... Decant overnight again (throwing away the bottom solids if theres any) . Repeat the salt-saturating step.. Do this total of 3x..
Then, in the last part one redissolves the harmala hcl that precipitated out of the salt saturated solution, and instead of saturating with salt, this time one adds the base until the whole thing changes colour, and then add a bit more just to make sure (dont worry one doesnt need to be exact, as long as all the colour changed). This time it will be freebase harmalas precipitating. Decant overnight in fridge again, throw out liquid, and only filter the very last part, keepign whatever stays on top of your filter.
enjoy, its a beautiful process with the colours changing and all
if one is so inclined its possible even to separate harmine and harmaline this way. The ph at which they become freebase is slightly different (dont know the numbers off the top of my head now), so one can slowly add sodium carbonate to a desired pH, let precipitate and filter one of them, then add more sodium carbonate and get the other one out. If you guys are interested I can check out the exact info (or you can find it yourselves)
