like blue.magic said, base that vinegar with lye and extract with a non polar solvent preferably naphtha so you can freeze-precipitate the DMT...
now if after scraping you are left with some DMT that you can't scrape, dissolve it in hot ethanol/iso and add to a bit of leaf, let it dry and and enjoy

good luck

"Is this the end of our adventure? Nothing has an end. We came in search of the secret of immortality, to be like gods, and here we are... mortals, more human than ever. If we have not obtained immortality, at least we have obtained reality. We began in a fairytale and we came to life! But is this life reality? We are images, dreams, photographs. We must not stay here! Prisoners! We shall break the illusion. This is Maya. Goodbye to the holy mountain. Real life awaits us." ~ Alejandro Jodorowsky
