Extraction 1: San Pedro Alkaloid Extraction For Dummies – Erowid
https://www.erowid.org/plants/cacti/cacti_chemistry2.shtml
Cactus: approx. 18” of 13cm diameter fresh Peruvian Torch.
Aqueous extraction with acidic water. Distilled white vinegar (what was on hand) to bring the ph down to about 4.
Then xylene to de-fat. I never noticed any fat layer in these steps except a few tiny drops of oil between layers, but the layers separated well other than that.
Basification with sodium hydroxide to a ph of around 10.
Extracted the free bases with xylene, then distilled white vinegar straight, to hopefully form some sort of alkaloid salts.
Used a little vinegar at a time but still went a bit overboard and the end result seemed to have too much vinegar because the ph was around 4. The vinegar was quite cloudy though so it seemed encouraging.
Evaporated in pyrex dish next to a fan. Ended up with nice clear crystals floating on a orange tinted oil (result of unsuccessful de-fatting?). I may have been able to get those crystals off the top before that oil dried. But, the whole thing ended up being scraped and mixed and dried thoroughly in a food dehydrator.
Ended up with a strange looking substance with nice crystals mixed with a waxy resin like san pedro tar.
Edible?
The pic quality isn't great, sry. The flash was washing it out then the ambient light wasn't great, tried a flashlight.

Cactus: what was left over from my previous two “tea” attempts, dried to powder. I should have weighed it at that stage, I know now. But using this stuff was kind of a practice run, and to see if perhaps the soaking in lye with xylene wold get any goodies left in there.
I do know it was around 9 lbs. altogether when it was fresh San Pedro. What that works out to in dried after being boiled once previously...
Using vinegar again to form salts, thinking vinegar is so weak, I went overboard and ended up with a slightly acidic cloudy solution.
Here's where I when awol on the directions though and tried adding a little baking soda to neutralize the ph.
I know, never toss together anything super dangerous that you don't fully understand. But, a little baking soda to neutralize vinegar water seemed harmless. I didn't make sodium acetate though did I?
When about neutral, it was into the pyrex pan for a day or so to fully evaporate. Ended up with a beautiful pan of sparkly crystals that were clear as ice in some places and sort of whitish in others, plus the yield was a lot more than expected at a just over 12 grams.
So, what got created here, anyone? Crystals have a ph of about 5 or 4.. They don't taste salty, maybe a tiny bit sour and bitter. What are they?
Edible?
P.S. Just so you guys know, I don't plan on doing this weird a/b extraction stuff with vinegar again. Next time I would get Citric or HCL I think. But, I'm even more leaning towards the food safe methods and the oil extraction method I just learned about here. Thanks for any input on my current experiments though. :thumb_up:
