Hello, I've come across information online that suggests that L-ephedrine and D-pseudoephedrine are the primary alkaloids found in ephedra, along with some other trace alkaloids. I think I’ve figured how to extract hydrochloride ephedrine and hydrochloride pseudoephedrine from ephedra and separating the two.
Could you please advise if I were to proceed with further meth synthesis, using methods like iodine/red phosphorus, should I use hydrochloride L-ephedrine, hydrochloride D-pseudoephedrine, or a mixture of both? Does the L/D have an impact on meth synthesis? Thank you.
I've encountered difficulty in distinguishing these concepts: ephedrine and pseudoephedrine, chiral L/D, optical rotation l/d, and I'm not sure how much they affect meth synthesis.
I used 15 grams of powder, each gram needs 1.656 ml, so 15 grams is 24.84 ml, but pouring ethanol and naphtha into the powder turned into mud. Excuse me, Great God, how can I filter it? There is no liquid at all, it's all mud.
There is a simplified method, which has been tested. Where does the powder obtained after heating with ethanol for 10 minutes in the first step go? Is it reserved for the second part? But in the second part, there is ethanol to soak for 3 days and naphtha to soak for 2 days, and then the two filtered liquids are fused. After fusion, a black substance with a lot of oil is obtained. I don't see powdery white.
Moreover, grinding grass into powder and soaking it in ethanol or naphtha is a dark green liquid. I filtered it with suction filtration for 4-5 times and the color is still dark green.
It was extracted step by step, but the final product was not white powder. I used a simplified version, and every step was done according to the above. After soaking in the solvent, the two solvents were combined, and after drying, a black one was obtained, no. It is a dark green liquid.
In theory, your ephedrine is there. You just need to extract it. There are also other substances. You need to completely evaporate liquid and crystallize ephedrine. Probably, flash chromatography is necessary here.
According to what you said above, I put it on the cake plate, but I haven't seen any white powder yet after evaporating the liquid. Is it a mistake in my operation? But I made it according to your above method.
I learned this method from one of my friends from Afghanistan. He said that they extract ephedrine with this method, but I haven't tried it yet because I'm looking for sulfuric acid.

In coming months I will attempt an extraction and post results.
