Raf-
what about THC?
Lacks nitrogen and is a terpenoid, like salvinorin A, and definitely gives a blue to purple colormetric reaction to the Marquis reagent (per SWIM's friendly neighborhood LEO).
Is there another test available to do research on?
SWIM thinks SWIM will mix up some Marquis and purify some salvinorin A xtals and find out for SWIMself, then report back.
Maybe that would make up for the crosspost...
