taurine extraction?
i want to know if there is a precedure to remove pure taurine from taurine supplement pills i believe each one is 500 mg of taurine so it wouldnt take
many to get a decent quantity but i want it to test its properties and to add to my colection of compounds found in energy drinks

Well I guess you would have to find out what other compounds are used as 'fillers' in the pills, and possibly find a solvent that would only dissolve
Taurine and not the other substances. Taurine is soluble in water.

wtf why would it say free from taurine but supposed to be a taurine pill? I hope its not homeopathic
Taurine contains both an acid and base so extraction sounds difficult

well if you have a scale weigh the pill, if it weighs .5 g then it is probably pure taurine

Ah ok I see
You want to get rid of the cellulose first. You cant use water since it will turn into goop. Maybe some sort of solvent like acetone that is capable
of dissolving taurine.

i was thinking about using the scale idea but i do not have an accurate enough scale and the cellulose is part of the cell and the shell can be pulled
apart quite easily

Why not just weigh 10, or 100 pills and divide by X amount of pills, etc, to find out the mass of the none taurine ingredients.

I believe taurine would be soluble in water over a large range of pH.
You could dissolve the pill in water, lower the ph to about ~1 if any ppt form, filter. Increase the pH to about 10 or 11, if anything ppts out,
filter. . .
Otherwise - you state the shell can come off quite easily. . . Its free form, no other ingredients, and you can take the capsule off. What else do you
want ?

According to this information sheet: http://www.chemicalbook.com/ChemicalProductProperty_EN_CB274... , taurine is quite soluble in water (5-10 g per 100 mL at 23.5 C). Because of the
sulfur atom and the squishiness of its electron cloud, it should be soluble in methylene chloride, chloroform, and DMSO due to London dispersion
forces. The amine group should allow it to dissolve especially well in chloroform. Using MeCl2 or chloroform would be nice because they are easily
evaporated.

If it does in fact dissolve well in DCM, I would extract with DCM first, then extract the taurine from the DCM with aqueous HCl.
