You're welcome. I figure if we can spare the mess and the filtering difficulties of having powdered seeds - it would make this process much easier.

The upper yield with Syrian Rue extraction is around 6% with crushed/powdered seeds.

My yield of 5.4% is 80% of a 6% yield. (I believe i may have lost some yield during the first filter fiasco)

So either the acid boils penetrate far enough to get 80%+ of the alkaloids from whole seeds.

OR

80%+ of the alkaloids are in the coating/shell of the seed.

Lets stop with the mess and just use whole seeds!
