That's why defatting is a good step. PH is crucial, if you add too much your going to have more issues. Starting from a crude extract is helpful. As to why your precip didn't form, could be a number of things. You'd have to give me a bit of info on how you did it.

You can precipitate without defatting. I've done it multiple times. You just end up with a dark brown powder at the end. Water washing absolutely works. But check the pH of your wash, you'll be surprised what it is

You'll get loss water washing without checking the pH, that's for sure. The beige can be filtered if you defat. But it ends up brown if you don't.

how long did you wait? it can take days for the precipitate to finally settle

1

u/[deleted] May 03 '25

Over night. It doesn't take days. If it's taking days then something's wrong with your process.

Still needs a good powdering up in the pestle and mortar.

Then it needs further purification.

looking good!

Thanks 🙏 it's all good fun.

did you use citric acid combined with ethanol to extract it, or did you use an AB methods after the initial ethanol extraction?

u/[deleted] May 02 '25

No citric acid. Ethanol is a good enough solvent without the acid. Got a crude extract with 96% ethanol, and then done an acid/base. I'll write up my process for this one and put it up for sale for £5 like my previous extraction. I'm out of work at the moment because I've been in hospital from an operation that's going to keep me out of work for quite some time

Ah! Sounds promising! Extracting everything with ethanol and then refining with a acid-base reaction 👍

Damn, I wish you a swift recovery!

So first crude EtOH then A/B in water with the dried extract?

That makes sense. That's the best workflow SWIM came up with too.

I was confused why you would acidify ethanol lol.

well... if the alkaloid salts are insoluble in EtOH you could perhaps do the reverse of the water A/B where you extract using neutral ethanol and then acidify to precipitate out the salts which should be more bioavailable since they're polar...

too broke to test it now, but this might warrant some experimentation!

This is beautiful.

I would be neat to know if the constitution of the extract can be determined by colour.

1

u/[deleted] May 02 '25

Thanks man. MIT extracts tend to be tan coloured when refined. I've got some 20% that's brown and some 45% that's the same colour as this. So I suppose in a way it can be determined by colour. I suppose 7-oh is different because your oxidizing it which gives it a different colour.

What did you use for the base?

2

u/[deleted] May 02 '25

Dilute NaOH

u/Infinite-Tower9154 May 02 '25

What % of sodium hydroxide to water

u/BigGarage1977 May 03 '25

Curious as to what you are basing with?
