yes. Tryptophan and tryptamine, as well as several of its derivatives, absorb strongly @ 280 nm, it is the wavelength of max. abs. observed in UV spectroscopy. These were samples in hexanes, 365 nm. benzyme attached the following image(s):  600327904.323076public.JPG (27kb) downloaded 147 time(s). 57888796377__6022D7B7-7363-43AF-B0BB-76221514DDDB.JPG (2,450kb) downloaded 142 time(s)."Nothing is true, everything is permitted." ~ hassan i sabbah

5-MeO, also in hexanes benzyme attached the following image(s): 600327908.760647public.JPG (42kb) downloaded 135 time(s)."Nothing is true, everything is permitted." ~ hassan i sabbah

What is the look of those liquids under normal light? Fully transparent or milky?
I guess it will work equally well for dissolved DMT salts in acid?
Can an ordinary ghetto chemist use a UV light to get a clue about DMT concentration?
Does the UV light destroy a small portion of the DMT?

No I meant the same hexane DMT solution under non-UV light. they appeared clear under normal light. if they were cloudy white, they would glow more intensely under UV; so as you inferred, some observations regarding concentration can be extrapolated from the intensity of the fluorescence.
