		<description>what exactly are you up to ?  trying to make your own energy drink?  If so, this is a dangerous thing.  too much of these chemicals can kill you.  And if you don&#039;t know what your doing you could injure yourself in the extraction process.

that said, follow the instructions here
http://www.erowid.org/chemicals/dmt/dmt_chemistry1.shtml

**** update ****
you didn&#039;t read the link did you?  You added ground up coffee beans to a polar solvent.   That won&#039;t work.  the alkaloids are in non polar forms.

follow these steps...
1) grind up material
2) add acidified water
3) let it sit
4) seperate the solids from the liquid via a coffee filter
5) repeat if you want
6) add basified water (NaOH + water) to pH 11 or so
7) cool
8) add nonpolar solvent.  Shake well
9) seperate the layers.  the alkaloid is in the non polar layer
10) repeat steps 8 and 9 if you want better yield
11) evaporate the non polar solvent
12) the residue is your alkaloids.

*** update 2 ***
vinegar is 5% acetic acid + flavorings.  acetic acid is a weak acid and the flavorings will be difficult to remove later.   It would probably work but I would suspect your yield will be low.  

both muriatic acid (hydrochloric acid) and sodium or potassium hydroxide should available in pure form at either a pool supply house or a store that sells water treatment chemicals.</description>

		<description>Alkaloids are more water soluble in acid so ethanol or isopropanol acidified with HCl should do the job</description>
