Alkaloids and corresponding solvents.

Migrated topic.
It's well known that harmalas are soluble in hot saline solutions.And insoluble in the cold saline solutions. Question is what is the minimum concentration of salt in water at which harmalas would stay insoluble. One know that 10%saline is fine, but can one go lower say 5 or even 1% solution ?
 
I can see this being a very useful list indeed! ill help out if there are any experiments that need filling in and add to it where-ever I can :)
 
LSA SOLUBILITY

SWIM's first crude LSA extraction used isopropyl alcohol and it was highly successful.

You can extract LSA from the seeds using the following solvents that SWIM tested:

Water
Isopropyl Alcohol
Ethyl Alcohol
Acetone
Methyl Ethyl Ketone

You can NOT extract LSA from the seeds using these solvents:

Naphtha (that includes V&P Naphtha, charcoal lighter fluid, etc.)
DCM (Dichloromethane)
Xylene
Heptane
Toulene

The LSA is present in the seeds in water soluble salt form. When in freebase form it is soluble in the following solvents that SWIM tests:

Water
Isopropyl Alcohol
Ethyl Alcohol
Acetone
Methyl Ethyl Ketone
DCM

On a related note: what solvents are these substances completely INSOLUBLE in?

For example: say SWIM patiently grew some large beautiful freebase crystals over a week and wants to encase one in a liquid for preservation and admiration. Would something like propylene glycol work?
