I didn't want to hi-jack anyone's threads, but this relates to the thread about the van urk solution, as well as possibly being useful/related to the ergot thread if there were ever an interest in trying to find a strain of it with high alkaloid productions.
I'd like to see as many different tests for alkaloids, and summaries such as the van urks reagant, etc.

* Classification of Alkaloidal precipitating agents:
1- Reagents that form double salts:
a- Mayer’s Reagent: Potassium Mercuric Iodide.
b- Dragendorff’s Reagents: Potassium Iodobismethate.
c- Gold Chloride.
2- Reagents Containing Halogens:
a- Wagner’s Reagent: Iodine/ Potassium Iodide.
3-Organic Acids:
a- Hager’s Reagent: Picric Acid
b- Tannic Acid.
4- Oxygenated High Molecular Weight Acids:
a- Phosphomolybdic acid
b- Phosphotungestic acid
c- Silicotungestic Acid
* Colour Reagents:
1- Froehd’s Reagent: Phosphomolybdic acid
2- Marqui’s Reagent: Formaldehyde/ Conc. H2SO4

I/we will need to add how to make, use and expect for these reagents.
This could also come in very useful when it came to finding a magic mushroom that contained higher alkaloids then general via the testing the mycelium of various strains.
