I find when doing the tek the "citric EA" jug will crash out a little more over a few days as does the based harmala jug. (only a small amount)

I usually decant the citric EA and use the harmala citrate goo for the next run. As for the FB harmala that crashes over a few days in the left over base jug, instead of being a nice white-grey harmala it too is a almost black crude harmala. I have no idea how much of it would be usable (could be worth a LC-MS). I always figured it was mostly impurities?

The reason I wrote up the tek to be as quick as it is, is because the end result is very decent purity and color (IMO) and can be done quick with very decent yields. One can always do repeat runs on spent material as well for a better yield. I guess I'm just impatient. The other reason for the quick tek as well, is, if you live in a country where harmala is illegal you can do it in a couple hours rather than having 'manufacturing evidence' sitting around for weeks.

I always figured it was just impurities in the base jug that crashed out when left for a few days or a week. At the very least it looks impure by color. I guess ammonia wash could clean it up and more harmala could be recovered?
