Correct me if I'm wrong, but it seems I read somewhere that the 25 comes from the fact that the inventor, Albert Hofmann, tried 25 extractions before coming up with pure LSD.
Um for cluster headaches a form of LSD was invented that doesn't induce tripping. Is that LSD-6? But I think the 25 extractions idea sounds more plausible.
Pretty sure it wasn't invented for that. I think it was just pulled out of what was known about LSD. There's 4 sterioisomers of LSD. Only one of them is psychoactive. There's a host of other lysergemides too, both developed by hoffman or by others. There where no 25 extractions, and nobody needs to guess about it's plausibility. LSD-25 was the original name for the 25th lysergemide that hoffman worked with. You don't extract LSD from anything, you start with ergotamine tartarate or lysergic acid, and work through a complex series of chemical reactions. (or, one of quite a few different complex series of chemical reactions)
^Okay I'll first start off by saying I'm a retard when it comes to science But I thought L.sD was synthesized and extracted from the fungus of rye ergot (sp?) From one of the chromosomesm, so isn't the 25th extraction theory possible?
Only some of LSD's make up is extracted from ergot, not LSD itself. What is extracted from ergot still must be reacted with other chemicals to make LSD.
No. LSD, again, is the product of a complex synthesis that starts with lysergic acid. There is no difference in the extraction of lysergic acid for that versus for another of hoffmans chemicals, and I highly doubt he was extracting it himself, though I could be incorrect. I expect by that point a lab worker was doing this. http://en.wikipedia.org/wiki/Lysergic_acid_diethylamide#Chemistry_and_structure Anyway, it's the 25th successful unique synthesis he undertook with ergot derivatives. It's nothing special about how you get your lysergic acid, it's what you do afterwards.
Dood... . here's the whole book. http://www.psychedelic-library.org/child.htm The true story, from THEE man responsible, in easy to grasp language. Now that he's gone, the foremost expert on LSD is Dr. David Nichols.
yes. (bromo is the short name) and yes! "extract" means to pull out something from inside something else. you could extract THC from cannabis, or psilocin from mushrooms, but you don't extract LSD from anything (at least that we know of), because we haven't found it to exist in nature (yet?) one "synthesizes" LSD, which is reacting chemical A with chemical B to make chemical C. different from extracting.
Not exactly. LSD-25 was the 25th synthesis in a whole long line of synthesis. It was the 25th synth he did to try and isolate a certain chemical from ergotamine. I believe he was trying to help discover something to stimulate blood flow. Regardless, the 25 means it was the 25th synthesis. There would be a 6 but it wouldn't be LSD, it would be a different Lysergic acid derivative....
