Hi Endlessness,
Thanks for your response.

On the flipside you can dilute the dmt sample a bit, it works fine as-is but ideally you want somewhat smaller spots to make sure that a too concentrated spot isnt hiding another spot nearby. Im sure thats not the case there, but i say this so to help for the future in getting the ideal concentrations for visualization. Also what you can do is try to use some ehrlich on the mangium columns at the same height as the dmt spot even if you dont see anything, because sometimes the spot cant be seen but with the reagent you might see a slight reaction.
Noted, I'll tell my friend to do this on the next TLC experiment. WRT concentrating the Mangium sample a bit more, he had problems getting it to dissolve in the solution. He's going to try and clean it up a bit (via a re ex or maybe some kind of mini A/B). This might remove more of the non active compounds and leave a substance that is easier to test.

Good stuff, I'll take a look.

Could you explain to me how you know this? I don't doubt you, but I'd just like to know how you can figure this out?

Unfortunately, that isn't going to be possible for a while. My friend managed to harvest this bark whilst we were on holiday in Thailand. I don't know when we'll be there again. Just so everyone knows, the bark samples were taken during the 'winter' season. The tree was not flowering nor were any seed pods growing.
He's thinking of trying some Phalaris extracts next, as they grow everywhere around here. It would be really awesome to find a local plant that contains spice :-)
endlessness wrote:By the way, thank you so much for sharing this, that is exactly what i was dreaming about when i started developing the tlc kits. Hopefully you find a plant with dmt there but in the meanwhile , a negative result is very positive in terms of knowledge gained.
No problem. Like I said, we've gotten so much from the posts here and we just wanted to give something back.
endlessness wrote:As for the spots present in the mangium, not sure what they could be, I will help you out gettimg this gc-ms tested , just give me some time since im quite busy and not at home. In the meanwhile you can gather more interesting samples and.tlc testing them and then we can gc-ms test the most promissing ones (or the ones with repeated unknown spots that will be useful to know what it is)
Be well!
That's great, thanks. If you think it's really worth looking into this further, just get in touch when you're ready to take this forward. No rush from my perspective.
Thanks again for all the assistance :-)
