#1

Anyone have experience or advice with CBG extraction. Best methods solvents. Generally SOP.

Avoid heat as much as you can. It converts to other compounds really easily

Appreciate it. It seems to be a very finicky cannabinoid. And everything needs to Ben done quickly with it

i wonder what my rosin has become then… Not enough to bother with testing, this was just some squished nug. Any data on the possible compouds created by heat?

I’ve been working with CBG for a long time. Despite what people fear I have never seen any evidence that CBG converts to other Cannabinoids during normal extraction, distillation and isolation. This is an enzymatic assisted conversion in the plant. I have done hours-long open atmosphere decarb/residual solvent removal and run serial distillations using the same material going as high as 180C (100mTORR) and never seen CBG convert to other Cannabinoids. Without a serious pH shift or something even less common during extraction I wouldn’t worry about converting CBG.

The biggest challenges you’ll face will be its tendency to crystallize at all stages of processing. This can cause issues in a rotovap or FFE among other things.
You may need to make some small tweaks to the recrystallization process if you do that.
Otherwise it’s a very similar process to CBD. If you run it like it’s CBD and keep in mind what I said above, you should have no trouble producing pure CBG. I’m available for consults should you want a more in-person run through.

Decarboxylation sure, but not converting to other Cannabinoids.
