Boiling kratom makes it luminescent, apparently!

I had a very watered down decant of kratom with some plant matter impurities that I decided to heat to evaporate quicker for dosing. Prior to this, it was a very light orangey-red and when shined on with a UV light, it was dark green. After the simmer, it turned very dark brown and looks like one of them glow in the dark dinosaur wall stickers under UV light.

This means that under heat, one of the chemicals in kratom are activated- and it stays activated too, as far as I can see. What does this mean for the other alkaloids? Is it worth it to boil before decanting? Let me know!
