Where are there instructions on how exactly to extract LSA from morning glory seeds?

A VERY brief overview of the extraction process: Grind Ipomoea seeds. Soak grounds in nonpolar solution. Filter out (then throw out) bulk of liquid, evaporate remainder. Soak in polar solution (ethanol), throw out grounds, evaporate ethanol, and you have your product.

Found this on a google search. There is a million ways listed, all involve alcohol, (ethanol).
