The Ephedra plant was dried and ground into powder, then extracted with anhydrous acetone. It was left at room temperature for two hours, filtered through a coffee filter, and left to sit for another 2–3 hours. A white precipitate formed at the bottom. What do you think this could be?

Is it liquid or solid? Looks like an emulsion.

Should I sprinkle starch on top? I don't understand.

SenWhat is the top layer?

 

[AKINCI]

acetone

ADraw the bottom white layer with a syringe then dry it

Hello, I recommend you to use Ephedrine extraction from plants second method with EtOH and naphta.

 

[AKINCI]

There is no naphtha in my country, teacher. Do you have any other suggestions? Thank you very much for your attention and response.

 

[G.Patton]

Petroleum ether, White spirit. You can google alternatives in your country.

Powdered ephedra plant Teacher, I will add white isporta to a 4-liter glass jar until it covers the top. Then, I will heat it to 32°C for 10 minutes, let it cool for 15-20 minutes, and filter it through a coffee filter. After that, I will wait for 12 hours for the sediment to settle. Is this correct?

Thank you for your answer.

And I will do the same process with ethanol, but I will not heat the ethanol and will let it sit for 3 days before filtering it. Then, I will combine these two solutions.

I am truly grateful for your interest—I'm so glad you exist!

Dry the ephedra, grind, add water and a few drops of HCL, cook for an hour, let cool and freeze. cook for another hour, filter through a cloth Boil the liquid so that it has as little volume as possible. Add non-polar solvent. The extract must be warm and add sodium hydroxide, mix carefully, extract the solvent and filter. Add a lot of water and HCl to the solvent, shake well, evaporate the water and hooray I have ephedrine

 

[AKINCI]

At what temperature should it boil?

 

[G.Patton]

Dude, what is boiling temperature? (answer: The temperature, when the mixture is boiling.)

 

[G.Patton]

It's about the same I posted. Acid-base extraction.
