Fluorescent Chicken Eggs, the Next Step

Fluorescent Chicken Eggs, the Next Step.
Some have posted pictures of Chicken Eggs in UVA Induced Visible Fluorescence.
Here is a example of what I have seen taking things a bit further.

The fluorescent component is protoporphyrin IX (and maybe some other porphyrins). You can extract it from the broken shells using vinegar, isopropyl alcohol and a little bit of salt.

This experiment also inspires my students again and again. A real highlight ;)
We also like the yellow fluorescence of parietin from Xanthoria parietina (also available "Down Under") and the blue/blue-green fluorescence of Fraxin and Esculin. But I don't know whether you have the corresponding trees (Fraxinus excelsior and Aesculus).
Here are a few ideas for further experimentation. Unfortunately it's in German, but the pictures and names speak for themselves.

I hope this is something new for you too ...

Very interesting, Col.

I have been wanting to try some floral pigment extractions for a long time. But never enough time!
