rue extraction ~ help
    #19230262 - 12/05/13 07:57 AM (10 years, 1 month ago)

I did something without thinking. I added extra water just prior to straining the solids in order to make the straining process quicker, without realizing that now it wouldn't conform to the measurements for the subsequent steps. I'm doing the RHF Manske extraction (see below). The next step calls for salt. I estimate that I'm working with 2.5 times as much as I should be. So, do I compensate by adding 2.5 times as much salt? Remember, the original solution is 60% vinegar and 40% water whereas the arbitrary additive was just water. And no matter how much I diluted the solution, it still contains the same amount of alkaloids.

This is extremely efficient and I understand is the technique used in the field to test for harmaline.

From "The Alkaloids" Vol II (p393), Mankse:

"The crushed seeds of Peganum Harmala are covered with three times their weight of water containing 30 g of acetic acid per liter of water [white vinegar is about 50g / l or 5 %]. The seeds swell as they absorb the liquid and form a thick dough which is pressed after 2-3 days. The pressed seeds are once more treated as above with twice their weight of dilute acetic acid and, after maceration, the liquid is again pressed out. To the combined liquors, sodium chloride [that's table salt, man] (100g. / liter of liquid) is added to transform the acetates of harmine and harmaline into the hydrochlorides which are insoluble in cold sodium chloride solutions and are precipitated during cooling. The supernatant liquid is siphoned off, the crystalline residue filtered with suction and redissolved in hot water.

Acetic acid is a weak acid... And after a few days probably isn't the same concentration you started with anyway...  So the pH probably didn't change that much unless you diluted it a lot... I would continue on, and if you used 2.5 times their suggested amount if seeds / acidic water, the  use 2.5 times the salt

Do you know how much water you added?

Worse comes to worse, you start over... Rue is pretty cheap

OK, just realized I could measure this. The liquid in the original soak was 84 ml and the water addition was about 91 ml. So, to recap, soaked ground seeds in water + vinegar; added water (which I was not supposed to do) to aid in straining solids from liquid; and now I have a liquid that needs the salt treatment.
