Harmine and harmaline hydrochloride crystals

Harmala alkaloids extracted from Peganum harmala (syrian rue) seeds, further purified by crystallization from brine.
These alkaloids are MAO inhibitors.
I further separate harmine and harmaline (DHH, dihydroharmine), the latter is further reduced to tetrahydroharmine (THH, leptaflorine) which is a weak SSRI with interesting benefits for central nervous system (could promote neuroplasticity).

I love that an extract from a plant called "rue" can be made into a weak SSRI. Funny. ;) Though from what I understand, plants usually get "rue" in their common name because they cause hayfever, not because they make people sad. Two different meanings of "rue," I guess.

Molybdenum heteropolyacids are my long-time favorites

Is it really blue? It looks white to me. Can you put it near a white background to make a contrast?

Playing with EDTA. Many complexes only seem to exist in solution. The copper-sodium complex retains its deep blue colour when the liquor evaporated, forming a glassy substance.

The lithium salt of the copper complex has the same deep blue colour in solution, but crystalises in a cyan-like variant of blue in tiny dull crystals.

The potassium salt of course has the same colour in solution, but separated into two phases on evaporation of the solution. A dark blue one, and one with the same colour as the lithium salt.
