Hello!
I'm happy for joining you.
SWIM wants to learn much about discarding gramine from yield. Sources of dmt in where SWIM lives are phalaris species and arundo donax. So he's got a problem: gramine. There are some informations about gramine on web, but most of all is not comfirmed. And people needs guide for getting gramine free yield and swim wants help for work.

Thank you all! And sorry for not good english.

I'm also interested in this. I've read that gramine is not soluble in naphtha but as you said, it's not confirmed...
