I’ve just been informed that literally every sample a lab has tested for a-toco acetate has come up positive in different concentrations. The lab managers’ opinion is that it’s naturally produced by the plant.
Anyone have any further information on this?
All I can seem to find is evidence that it’s in hemp seed oils. That at least tells me the plant is capable of making it, no surprise really.
Anyone had any of their oils tested for it?
Hey ExTek90
It’s not my source material, but NBC did a testing review of 18 cartridges and found that the 3 they had sourced legally contained 0.0% Vit E acetate. The article was relatively recent and should be a short google search away.
Now, I haven’t seen any raw numbers, and I hate their experimental design (who gets 18 carts and divides that as 15 black market and 3 legal, who the fuck designed this) but it at least lends some evidence you might enjoy
I’m thinking there’s a chance that hydrocarbons aren’t very good at grabbing it based off some stuff I’ve been reading.
I would also like to point out there there are 8 different isoforms of Vit E and only some of them have been found to produce negative reactions in asthma patients, while other isoforms have been found to IMPROVE asthma. Whichever version the plant is theoretically producing is important to know.
a-tocopherol and ß-tocopherol are both derived from terpenes. If I’m not mistaken they’re caratenoids that are also considered terpenoids (?) But they are derived from plant terpene pathways.
my guess is they were trying to be as cheap as possible and based it off petty cash funds. if i recall correctly, 10 of the black market cartridges were all the same strain from the same vendor and to no surprise, they all failed for myclo because they were all the same. “10/10 black market cartridges contained hydrogen cyanide” makes for a much more enticing headline though. if they did 10 different cartridge black market brands and all 10 failed, then yeah there’s a pretty big problem.
they may have only tested for alpha-tocopheryl acetate, not alpha-tocopherol. not sure if that holds any significance though.
After some more digging, I’ve found several studies measuring the tocopherol content in cannabis.
Isoforms is a term used for proteins if I’m not mistaken.
In regular chemistry, the different conformations here are referred to as stereoisomers and yes Tocopherol acetate has 8. Not only is the individual isomer important but also the mixture of isomers present
Not saying it’s correct, but most papers I’ve read on the topic do use isoforms, like:
Can you link to them here? And is it acetate or just tocopherol?

Thank you very much for the nomenclature help, I studied proteins for years and am definitely more of a biologist than a chemist 
Interesting, only ever seen it used for large proteins. Small molecules were always isomers. Learn something everyday
Real quick if you look at those journals, they are biology journals. Different branches of science call the same thing different names.
Same molecular formula, different connectivity is a constitutional isomer in chemistry.
The different firms of vitamin E have one functional group in a different location. I’d call that a regioisomer.
Thanks, yea I was referring to just tocopheryl acetate. I see now they are more than one homologue of it that are being referred to as isoforms
