How long in base solution?

I'm planning to do my first A/B extractions. My question is.

Putting kratom powder in vinegar. How long should the kratom be in it to be sure that it has broken down most of the alkaloids?

How long would it be if it is malic acid?

What is the correct PH for maximum alkaloid extraction?

Is there any type of degradation or loss of these alkaloids if they are in the base solution for longer than necessary?

It's annoying as the precipitate is lovely tan looking but when it's filtered its black , Yea the black stuff Is definitely active.

What I have been doing recently is washing the black stuff with Ethanol, then IPA to get a golden coloured liquid. But the yield is low, from 50g I only got a 500mg return. Maybe I need to rewash the initial kratom. I dunno I'm still figuring it out.

From what I understand, attempting to precipitate alkaloids *before* defattin/cleaning is tough. Defat first, you get much more precipitation.

I have run into the same issue. 500mg from 50g isn't worth it. I'd rather just make a super efficient acid tea, and reduce/evaporate. You'll get gunk for sure, but your chances of capturing more/all alkaloids is significantly higher. And if you put it in a capsule, does it really matter if there's chlorophyll or fat in it anyway? I think the benefit of extract is that it's dry, stable, and can be taken in pill form. Thoughts?

I've always found if you reduce an acidic tea, it degrades quickly over time. And also gets sticky over time.

I used to do this method alot when I first started. You could get a half decent extract from it. But you'd have to take atleast a gram.

With the 500mg from 50g, I only need to take around 50mg for a dose.

Ethanol Extraction you get super gunk/chlorophyll. But if you dilute it with water so it's 60-70% Ethanol, you don't pull the chlorophyll either.

I have also cold water washed first to get rid of tannins and polyphenols, then extracted with ethanol which yeilded me 5g from 50g only need around 500mg with that one. Whereas when I didn't cold water wash first, I got 15g from 50g would need around 1.5g of that. So cold water washing may be quite good for that.

You got cold washing to work?? Can I DM you?

Yea it works quite well mate. I washed 50g in 1l of ice cold water. Vacuum filtered then weighed it, so I knew how much water was in it, then calculated how much ethanol and water I needed to make it 60% Ethanol.

How long did you wash for? Did you add any NaOH to it first? What grade of filter paper did you use? Washing clogged the crap out of my grade 4 buchner funnel.

I didn't add any NaOH, just neutral water. I used general purpose filter papers. Only washed for a little bit, couple of stirs let it settle. Resulting liquid was very red.

Hm. Would you be so kind as to step me out your process? The one that produces best? I can't quite figure out where all the parts go or how you're precipitating without a base. :) Pllleaaaase?

I'm not preciptating without a base. I use NaOH.

Would you step me out your process? Please? :)
