Looking for an efficient route to IPA extraction from fresh material

[blig-blug]

I have a decent amount of cactus material (but not necessarily of actives) and want an IPA-extracted full spectrum resin (following @doubledog's tek) as the end result.

So far, I've been boiling the cacti, evaporating the liquid until resin combining several boils (with freeze-thaw cycles for the cacti), and cleaning that crude resin with IPA.

This works well, however it is extremely time consuming, as the cacti stay noticeably bitter in their greener surface areas even after four or five boils. So I'm looking for more efficient ways.

An option that I have thought of is squeezing the fresh cacti and collecting their dry juice, and then evaporating it intto a very crude resin that would be cleaned with IPA. I would also let the pulp dry (it should be much faster after it having been squeezed, and can maybe heat it up in a hot water bath) and extract that with IPA too.

Anyone has done anything similar, or has any comments or ideas?

Water and cactus is always lot of work. Do not bother.
I would extract dried cactus powder with ipa/water solution. Or alkaline alcohol.

Not that you have a soxhlet but I did a bunch of reading and stumbled across this gem Mescaline quantification in live cacti using TLC from An1cca which has a PDF attachment. In the attachment the first half covers mescaline quantification via TLC and in the second he does an alkaline ethanol extract via soxhlet.

That came to mind when doubledog mentioned alkaline alcohol.

Soxhlet would be great, but even without it, extraction using alkaline alcohol is quite easy. It's especially usefull for processing lot of weak cactus.

As there is a pH change, it's a question if we could still call it full spectrum.

That extract I linked I feel was worthy of a share but don't want to redirect the thread. I have a soxhlet and ran into it after searching here on the Nexus. Mine is 1000ml and I don't have a thimble yet but I've estimated you can process ~100-125g of dry powder as a reference point which doesn't scale massively to but can swap thimbles out which An1cca mentions.

I'm following along and interested on the discussion. I was following along in the Defatting/Purifying San Pedro Resin thread but admittedly started to get lost in regard to broad stroke implications of some of the modifications resulting in the subsequent affect.
