General Methods of Extraction and Isolation of Alkaloids

07/07/2012  (a) Soxhlet Extraction Process: The soxhlet assembly is a continuous extractor which is generally suitable for the extraction of alkaloids from powdered plant materials with the help of organic solvents. In this instance, the powdered drug is usually moistened with dilute ammonia solution and then packed loosely in the thimble of the Soxhlet apparatus; and the organic solvent affords a deep penetration of the moist drug thereby allowing the greatest possible extraction

Extracting Essential Oils in the Lab Phytochemia

04/08/2014  After typically 2 h of extraction (calculated from the first condensed drop), we can measure the volume of oil recovered and calculate the yield from the mass of plant introduced. This technique has the advantage of allowing us to recover the hydrosol. It also allows us to perform extractions on larger quantities of plants. For example, in the picture above, we are extracting 1.25 kg of cow parsnip stems
