Is it possible to extract Hydroxy alpha sanshool from szechuan pepper and if so how?
Doesn't have to be particularly pure, I'd just like to be able to have a better concentration of it for cooking than you typically get from the peppers themselves.

Could I just soak some ground peppers in alcohol or lighter fluid, strain it then allow it to evaporate?

I think it's oil soluble. So you could powder the peppercorn, then put it in hot oil for a few minutes, filter it, then heat again with more peppercorn. I think that would work, but I'm not sure.

Or The molecule looks like it would be more water-soluble in acidic conditions. So you could add a bit of vinegar to water, then boil the shit out of the pepper.

Make sure you're using the whole berries, not the powder (which tends to have way less numbing).

The powder is the whole berries, that's the thing. I need it in a non-fatty solution, I'll try vinegar. Thanks.

The powder is nowhere near as potent. It loses the numbing qualities. Get some of the dried whole spice. It's more expensive, but way more potent. That's the shit that makes your mouth numb and tingly.

Also, I'm not 100% sure about the vinegar. The molecular does look very hydrophobic, even when protonated.

If the water doesn't work, then try some rubbing alcohol (obviously evaporate it before using).

I mean the powder is literally just the whole spice that's been ground up. I did it myself. You're right that it doesn't have the same effect when eaten but I don't understand why that would cause there to be any less of the active chemical. I was just doing it to make the extraction more effective with the higher surface area.

Oh, gotcha. I was talking about the store-bought powder that's been sitting around for months. It barely has the numbing effect at all, it's just the flavour.

Nah I'm 90% sure the store bought stuff is just as strong. There's a significant difference in the tongue-numbing effects before and after grinding. Could be something to do with where the chemical is on the pod so it's there when you bite it but not if it's "diluted" by being mixed in with the rest of the pod, that's my only theory.

Do the bitterants evaporate with the rubbing alcohol? I can't get everclear or anything like that in this country.

I swear I replied to this before, but I guess I didn't.

I don't think there's bitterants in IPA (rubbing alc). i could be wrong, but I just don't think that's a thing in the US. In your country? I also doubt it's a thing. Drinking IPA is a last, last resort. The gov doesn't need to make it bitter to discourage it.

Also, you could definitely try an extraction with plain vodka. Try to get a high proof (surely your country has 50% vodka?!)

I'll probably try this as the other options are mad rare or expensive. Thanks all.
