Open this PDF (2.14MB) Chilled acetone extraction.pdf This extraction method reduces the amount of waxy compounds extracted from the leaf yielding a much purer extract. Simple refinement methods are explained using naphtha and 99% isopropanol to dilute and if desired completely remove waxy lipids from the extract at increasing cost to yield for higher purities. Over 50 photographs showing the process of extracting leaf and refining the extract. Last edit 02 April, 2006. | |
